Best 1000 Watt Hps Grow Light for Bulbs and Systems
A strong 1000-watt HPS grow light should match your fixture and ballast while delivering the spectrum and output your plants need; this selection suits indoor growers choosing a replacement bulb or a complete HID system. The GRUOTVSZAK HPS 1000W E39 2-Pack leads for its stated 1,950 μmol/s output, 136,000 lumens and claimed 24,000-hour lamp life. Other options span double-ended lamps, single-ended E39 bulbs, a seven-pack and a dimmable system with wattage settings from 600 to 1,150 watts.
Those formats are not interchangeable: check your fixture, ballast and operating voltage before choosing. The listed output figures also use different measures, so compare like with like rather than treating lumens and PPF as equivalent.
Our ranking weighs stated specifications and use-case fit, not independent testing.
The GRUOTVSZAK HPS 1000W E39 2-Pack is the leading pick because it combines a stated 1,950 μmol/s PPF, 136,000 lumens, an E39 base and two bulbs per listing. Its claimed 24,000-hour total life and 90% output maintenance for 5,000 hours add useful longevity details absent from many listings. Confirm that your fixture and ballast support a 1000-watt, single-ended E39 HPS lamp before buying; the listing says full brightness takes five minutes.

Detailed Reviews: Best 1000 Watt Hps Grow Light

#1 · Best Overall
1. GRUOTVSZAK HPS 1000W E39
- Wattage: 1000 W
- Light Source Wattage: 1000 W
- Material Type: Glass
Best for: Red-focused flowering bulb pair.
Why it ranks #1: Lists 1,950 μmol/s PPF, 136,000 lumens, an E39 base and a claimed 24,000-hour life; the two-pack also supplies a spare.
A stated 60% increase in PAR focused on red gives this 1000-watt E39 HPS pair a clear flowering-stage emphasis. GRUOTVSZAK lists 1,950 μmol/s PPF and 136,000 lumens, figures that help growers compare its output while planning a bloom-focused setup.
The red-focused PAR is intended to improve light utilization for photosynthesis during flowering, making the spectrum the central reason to choose this bulb. Its 1000-watt rating and E39 base identify the lamp and fitting type for a compatible fixture. The listing gives a 5-minute warm-up to full brightness, so growers should allow that interval after startup. A stated 24,000-hour total life and 90% output maintenance through 5,000 hours also provide reference points for planning replacements.
- 60% more PAR focused on red, per listing
- 1,950 μmol/s PPF stated
- 136,000 lumens stated
- Two E39 1000-watt bulbs included in the listing
- Requires a compatible E39 HPS fixture and ballast, which are not listed as included.
Skip it if you need a complete lighting system rather than two bulbs; the UltraGrow Classic 1000W DE system includes a dimmable ballast and HID bulb.
Choose this pair if your compatible E39 HPS fixture needs bulbs with a stated red-heavy flowering spectrum. The two-bulb listing suits growers planning replacements or a pair installation; allow five minutes for full brightness and verify fixture compatibility.

2. iGrowtek 1000W DE HPS
- Wattage: 1000 W
- Light Source Wattage: 1000 W
- Material Type: Quartz Glass
Best for: High-lumen double-ended bulb.
Why it ranks #2: Its double-ended format is paired with stated 155,000 lumens, 2,000K color temperature and 220-volt operation for compatible fixtures.
A stated 155,000 lumens and 2,000K color temperature make the iGrowtek 1000W double-ended HPS bulb a high-output, red-and-yellow option for compatible DE fixtures. Its quartz-glass construction and 220-volt specification give buyers concrete details for checking lamp and system fit.
The double-ended format identifies the fixture style this lamp is intended to pair with, while its 1000-watt rating and 220-volt specification help buyers check electrical compatibility. The stated 155,000 lumens provides an output figure for comparison, and the 2,000K color temperature with red and yellow light describes its spectrum. The listing names one bulb, not a ballast or fixture. iGrowtek also advises wearing protective lenses when operating near an HPS lamp.
- 155,000 lumens stated
- 2,000K color temperature
- Double-ended HPS format
- 220-volt specification provided
- The 220-volt specification requires a compatible electrical setup.
Skip it if you want an E39 single-ended bulb; the Growlite HPS 1000W Real Red Grow Lamp lists an E39 mogul base.
The iGrowtek bulb suits growers with a compatible 220-volt double-ended fixture who want a stated 155,000-lumen HPS lamp. Treat the electrical specification and DE format as essential fit checks, and follow the listed protective-lens advice near operation.

#3 · Double-Ended Pick
3. YauldSun DE HPS 1000W
- Wattage: 1000 W
- Light Source Wattage: 1000 W
- Material Type: Glass
Best for: Double-ended flowering bulb.
Why it ranks #3: This 2100K double-ended lamp lists 151,000 lumens and 210 volts, offering a clearly specified option for compatible DE systems.
YauldSun’s double-ended construction is paired with a stated 151,000 lumens and 2,100K red-and-orange spectrum in this 1000-watt HPS bulb. The combination gives indoor growers a flowering-focused lamp with a clearly specified format and output to assess against their compatible setup.
The listing says the double-ended system delivers light evenly and without obstruction, which is the practical distinction for growers selecting a DE fixture rather than a single-ended socket. Its 2,100K red-and-orange spectrum is described as supporting abundant harvests, while the 151,000-lumen figure offers an output reference. The specifications list 210 volts, so buyers should check their system’s electrical requirements before installation. This listing is for one bulb, not a complete fixture.
- Double-ended lamp format
- 151,000 lumens stated
- 2,100K red-and-orange spectrum
- 210-volt specification provided
- Its 210-volt specification limits it to systems that support that voltage.
Skip it if you need a standard E39 bulb; the Growlite HPS 1000W Real Red lamp lists an E39 mogul base.
Choose this YauldSun bulb if you have a compatible double-ended fixture and want a stated red-and-orange 2,100K spectrum for indoor cultivation. Its 210-volt specification is a key fit check, and the single-bulb listing does not include a fixture.

#4 · Complete Grow System
4. UltraGrow Classic 1000W DE System
- Wattage: 1000 W
- Light Source Wattage: 1150 W
- Material Type: Aluminum
Best for: Dimmable DE system for growers.
Why it ranks #4: Unlike bulb-only listings, it includes a dimmable ballast and bulb, with selectable settings from 600 to 1,150 watts and ETL listing.
Five selectable wattage settings, from 600 to 1,150 watts, make the UltraGrow Classic a system for growers who want output control rather than a fixed-output bulb. Its included HID bulb, dimmable ballast, and 95% reflective hammertone reflector define the bundled setup.
The wattage control steps—600, 750, 825, 1,000, and 1,150—let growers select among listed operating levels as their setup requires. Input voltage options of 120V, 208V, and 240V broaden the system’s stated electrical choices, while the included 10-foot power cord and 240V adapter support installation planning. The reflector is specified as 95% reflective hammertone aluminum. At 22 pounds and 26 by 10 by 5 inches, this complete system needs space and secure mounting.
- Dimmable settings from 600 to 1,150 watts
- 120V, 208V, and 240V input options listed
- 95% reflective hammertone reflector
- 10-foot power cord and 240V adapter included
- The 22-pound system is heavier to handle and mount than a replacement bulb.
Skip it if you only need a replacement lamp; the Ushio US5002442 Bulb Pro Plus HPS 1000W Double Ended is listed as a bulb.
This system fits growers who want a dimmable DE setup with a ballast, bulb, and reflector together. Its 22-pound weight and listed dimensions matter when planning mounting, while the selectable input voltages help guide electrical setup decisions.

5. Vegelumax 1000W E39 HPS
- Wattage: 1000 W
- Light Source Wattage: 1000 W
- Material Type: Glass, Tungsten
Best for: High-output E39 hydroponic bulb.
Why it ranks #5: A single-ended E39 bulb with 140,000 stated lumens, 2100K color temperature and listed compatibility with electronic and magnetic ballasts.
Vegelumax pairs a stated 140,000-lumen output with a 2,100K red-and-orange spectrum in this 1000-watt E39 HPS bulb. That combination gives hydroponic growers a clear flowering-oriented lamp specification to weigh when selecting a replacement for a compatible ballast and fixture.
The 2,100K color temperature and red-and-orange spectrum are described as supporting flower growth, fruiting, and harvests, so the lamp is aimed at cultivation rather than general room lighting. Its E39 base identifies the required socket, while the listing states compatibility with electronic and magnetic ballasts. That compatibility can help buyers checking an existing setup, but it does not remove the need for a matching 1000-watt fixture. The listing specifies one bulb.
- 140,000 lumens stated
- 2,100K red-and-orange spectrum
- E39 base
- Listed as compatible with electronic and magnetic ballasts
- The listing is for one bulb, not a complete fixture or lighting system.
Skip it if you want a bundled dimmable system; the UltraGrow Classic 1000W DE system includes its HID bulb and ballast.
This Vegelumax bulb suits growers with a compatible E39 fixture who want a listed red-and-orange 2,100K lamp for hydroponic flowering and fruiting. It is a replacement bulb, so plan separately for the fixture and ballast required to operate it.

#6 · Enhanced Spectrum
6. Hortilux Super HPS 1000W
- Wattage: 1000 W
- Material Type: Metal
Best for: Enhanced-spectrum Hortilux lamp.
Why it ranks #6: Its description says it provides 25% more energy in violet, blue and green spectrum than standard HPS, a distinct spectral emphasis.
Hortilux specifies 25% more energy in violet, blue, and green spectra than standard HPS, distinguishing this 1000-watt Super HPS lamp from a red-focused option. That added spectral emphasis gives growers considering broader plant-stage coverage a specific point to compare against their existing lighting plan.
The stated increase in violet, blue, and green energy provides a concrete spectral distinction for growers evaluating a Super HPS lamp. Hortilux also says combining Super HPS with its Metal Ace conversion lamp provides optimum spectral energy levels through all plant-growth stages. That makes this lamp relevant to a setup planned around that combination, rather than a standalone claim of full-stage coverage. The supplied specifications identify 1000 watts and a brass base; check the fixture requirements before installation.
- 25% more violet, blue, and green energy than standard HPS, per description
- 1000-watt rating
- Brass base material stated
- Super HPS and Metal Ace combination described for all growth stages
- All-stage spectral coverage is described for use with the Metal Ace conversion lamp, not this lamp alone.
Skip it if you need a complete system with ballast and reflector; the UltraGrow Classic 1000W DE system lists those system components.
Consider this Hortilux lamp if its violet, blue, and green spectral emphasis fits your cultivation plan, especially alongside the named Metal Ace conversion lamp. It is a 1000-watt lamp, so confirm your fixture supports its base and operating requirements.

7. Growlite Real Red HPS 1000W
- Wattage: 1000 W
- Light Source Wattage: 1000 W
Best for: E39 red-spectrum flowering lamp.
Why it ranks #7: The single-ended E39 lamp lists 1,400 μmol/s PPF, 2000K and ANSI S52 compatibility, with a flowering-oriented red and far-red spectrum.
Growlite specifies 1,400 μmol/s PPF and a 2,000K deep-red spectrum for this 1000-watt E39 HPS lamp, giving flowering-focused growers two concrete selection details. Its ANSI S52 compatibility and 250-volt, 4.7-amp operating specifications further clarify the intended system fit.
The strong red and far-red output is described as supporting flowering and fruiting, aligning the lamp’s spectrum with those stages. Its E39 mogul base suits compatible screw-in fixtures, while ANSI S52 compatibility and the 250V, 4.7A specifications give growers system details to check before installation. Growlite also notes that single-ended HPS lamps run cooler than double-ended lamps, making this format relevant where reducing heat is a consideration. This listing is a lamp, not a full system.
- 1,400 μmol/s PPF stated
- 2,000K red and far-red spectrum
- E39 mogul base
- ANSI S52 compatibility specified
- Its 250-volt, 4.7-amp operating specification requires a matching setup.
Skip it if you need a bulb with a stated 155,000-lumen output; the iGrowtek 1000W Double Ended HPS Grow Light Bulb lists that figure.
Choose this Growlite lamp if you need an E39 single-ended option for an ANSI S52-compatible setup and prioritize a deep-red flowering spectrum. Check the stated 250V and 4.7A requirements against your system before installing the 1000-watt bulb.

8. Ushio Pro Plus HPS 1000W DE
- Wattage: 1000 W
- Light Source Wattage: 1000 W
- Material Type: Glass
Best for: Ushio professional DE bulb.
Why it ranks #8: A professional-grade double-ended lamp with stated 1000-watt output and a full-line horticulture-lamp description, but fewer decision specs are listed.
Ushio identifies this 1000-watt Pro Plus lamp as a double-ended Hi-LUX GRO horticulture bulb, with super high output technology cited for vegetative growth. That product-line positioning gives growers seeking a named professional-grade DE lamp a specific option to assess for their compatible fixture.
The double-ended construction is the key fixture-format detail, while the 1000-watt rating helps buyers match the bulb to an appropriately specified system. Ushio describes its Hi-LUX GRO line as professional-grade horticulture lamps using super high output technology for vegetative growth. The listing also specifies 120 volts, a glass body, and a 16.75-inch height, which can inform electrical and space checks. It is a bulb listing, so the supplied facts do not describe a bundled ballast or fixture.
- Double-ended lamp format
- 1000-watt rating
- Hi-LUX GRO horticulture lamp line
- 120-volt specification and 16.75-inch height stated
- Its listed 120-volt specification must match the intended DE system.
Skip it if you need a complete dimmable lighting system; the UltraGrow Classic 1000W DE system lists a ballast, bulb, and reflector.
This Ushio bulb suits growers looking for a named Hi-LUX GRO double-ended horticulture lamp and whose fixture matches its 1000-watt and 120-volt specifications. Check physical clearance for its listed 16.75-inch height; the listing is for the lamp alone.

9. Hortilux Super HPS 7-Pack
- Wattage: 1000 W
- Light Source Wattage: 1000 W
- Material Type: Glass
Best for: Seven-bulb Hortilux supply.
Why it ranks #9: The seven-pack supplies multiple 1000-watt Super HPS bulbs, but the listing provides limited performance detail and fits bulk replacement needs best.
A seven-bulb pack is the defining practical feature of this 1000-watt EYE Hortilux Super HPS listing. It gives growers sourcing multiple replacement lamps a single pack to consider, while the Digital Ready title and yellow HPS light identify the product’s stated lamp category.
The seven-pack format can simplify purchasing when several compatible lamp positions need replacement at once. Each listed lamp is rated at 1000 watts, and the specifications identify a yellow light color and R25 bulb shape size. The title calls the lamps Digital Ready, a useful detail for buyers comparing them with a digital-ballast setup, though the supplied facts do not specify ballast compatibility beyond that wording. This is a bulb pack, so plan for suitable fixtures and operating equipment separately.
- Seven lamps in the listed pack
- 1000-watt rating
- Digital Ready wording in the title
- R25 bulb shape size stated
- A seven-bulb pack is more than needed when replacing only one lamp.
Skip it if you need just one replacement bulb; the iGrowtek 1000W Double Ended HPS Grow Light Bulb is listed as a single lamp.
This pack fits growers replacing several 1000-watt Super HPS lamps or keeping compatible spares on hand. Its seven-bulb quantity is the main buying consideration; check that your fixtures accept the specified R25 lamps and suit the Digital Ready designation.

10. InterLux Extreme HPS 1000W
- Wattage: 1000 W
- Light Source Wattage: 1000 W
Best for: Red-spectrum flowering bulb.
Why it ranks #10: It is a 1000-watt HPS bulb described for flowering and electronic ballasts, but provides few measurable output or compatibility details.
The InterLux Extreme HPS is described as a 1000-watt lamp with a spectrum shifted toward red, giving indoor growers a clear flowering-stage focus. Its description also states that it was developed to work with electronic ballasts, a useful compatibility detail for buyers checking their existing setup.
The red-shifted HPS spectrum is specifically associated in the description with flowering stages, making that the clearest use case for this lamp. Electronic-ballast operation is also explicitly stated, which helps narrow compatibility checks when selecting a replacement. The supplied specifications identify a 1000-watt rating and red light color. No lumen or PPF figure is provided in the supplied product facts, so buyers focused on those output measures will not have one here for comparison.
- 1000-watt rating
- Red light color specified
- Red-shifted spectrum described for flowering
- Developed to work with electronic ballasts
- The supplied product details give no lumen or PPF output figure.
Skip it if you require a stated PPF figure; the Growlite HPS 1000W Real Red Grow Lamp lists 1,400 μmol/s PPF.
This InterLux lamp fits indoor growers seeking a 1000-watt, red-shifted HPS bulb for flowering and an electronic-ballast setup. Its supplied details do not state lumen or PPF output, so buyers who compare by those measures should account for that limit.

View on AmazonAvoid the ballast and base mismatch
Check the lamp base, ballast type and operating voltage together before ordering; a 1000-watt label alone does not establish compatibility. GRUOTVSZAK HPS 1000W E39 and Vegelumax 1000W E39 HPS specify E39 bases, while Vegelumax explicitly lists compatibility with electronic and magnetic ballasts. Growlite Real Red HPS 1000W names ANSI S52 and 250 volts, and YauldSun DE HPS 1000W lists 210 volts.
Those details point to meaningfully different setups, not universal replacements. Double-ended lamps such as iGrowtek 1000W DE HPS and the YauldSun model require a fixture designed for that format; an E39 screw base will not substitute.
The UltraGrow system lists input voltage options of 120V, 208V and 240V. Match the lamp and ballast manuals to your actual fixture and supply, and do not infer compatibility from wattage or brand alone.
Interpret lamp output claims carefully
Do not compare lumen and PPF figures as though they were the same measurement. GRUOTVSZAK HPS 1000W E39 reports both 1,950 μmol/s PPF and 136,000 lumens, while iGrowtek 1000W DE HPS lists 155,000 lumens and Growlite Real Red HPS 1000W lists 1,400 μmol/s PPF. These figures describe different aspects of light, and the listings do not provide a common test method or equivalent coverage area.
A higher number in one unit therefore does not establish that one lamp will outperform another in your grow space. Also note that the GRUOTVSZAK listing says to allow five minutes for full brightness, so an immediate visual check can be misleading.
Use comparable measures where available, and treat claimed output and lifespan as listing specifications rather than independently verified results.
How to Choose a 1000-Watt HPS Grow Light
Single-ended or double-ended format
Choose a lamp format your fixture is built to accept; base and socket design are not interchangeable. GRUOTVSZAK HPS 1000W E39 and Vegelumax 1000W E39 HPS specify E39 bases, while Growlite Real Red HPS 1000W also identifies an E39 mogul base. YauldSun DE HPS 1000W and iGrowtek 1000W DE HPS are double-ended, and the UltraGrow Classic 1000W DE System is a DE system.
Buyers replacing a screw-in mogul bulb should focus on the single-ended E39 options. Growers who already own a compatible double-ended fixture can consider the DE lamps; confirm the socket and ballast requirements before ordering rather than relying on wattage alone.
Output and spectrum priorities
Compare output using the same measurement and choose a spectrum suited to your intended growth stage. Listed lumen figures range from 136,000 for GRUOTVSZAK HPS 1000W E39 to 155,000 for iGrowtek 1000W DE HPS; YauldSun DE HPS 1000W states 151,000 lumens. PPF claims include 1,950 μmol/s for GRUOTVSZAK HPS 1000W E39 and 1,400 μmol/s for Growlite Real Red HPS 1000W.
Vegelumax 1000W E39 HPS lists 140,000 lumens and a 2100K spectrum, while Hortilux Super HPS 1000W emphasizes extra violet, blue and green energy. Buyers prioritizing stated lumen output may prefer the iGrowtek; flowering-focused buyers may favor red-spectrum descriptions, while treating claims as specifications, not comparative test results.
Bulb-only purchase or complete system
Decide whether you need a replacement lamp or the supporting fixture and ballast too. Most entries here are bulbs, including GRUOTVSZAK HPS 1000W E39, which lists two lamps, and the single-bulb Vegelumax and YauldSun options. The UltraGrow Classic 1000W DE System is the clear system listing: it includes an HID bulb and dimmable ballast, offers settings from 600 to 1,150 watts, and lists 120V, 208V and 240V input options.
Existing growers with a verified compatible ballast can choose a bulb-only product and avoid buying a system they do not need. Someone assembling a setup may find the included ballast and bulb useful, but should still verify voltage, fixture format and installation requirements.
Which 1000-Watt HPS Grow Light Should You Choose?
Choose GRUOTVSZAK HPS 1000W E39 if you need a single-ended E39 lamp and value its stated 1,950 μmol/s PPF, claimed lifespan and two-bulb listing. For a compatible double-ended fixture, iGrowtek 1000W DE HPS lists the highest lumen figure here at 155,000; YauldSun DE HPS 1000W is another DE option with 151,000 stated lumens. If you need a ballast and bulb together, choose UltraGrow Classic 1000W DE System for its dimmable 600-to-1,150-watt settings, after checking its input-voltage options against your setup.
Growlite Real Red HPS 1000W suits shoppers seeking a stated 1,400 μmol/s PPF and ANSI S52 specification. Whatever the pick, verify fixture format, ballast and electrical compatibility before ordering.
Frequently Asked Questions
How can I tell whether my ballast and fixture support a single-ended or double-ended HPS lamp?
Check the fixture and ballast labels or manuals for the supported lamp format, wattage, base, and electrical requirements. Single-ended E39 lamps and double-ended lamps are different formats; do not assume one fits or works with the other. If the documentation is unclear, confirm compatibility with the fixture or ballast manufacturer before buying.
How much distance should I leave between a 1000-watt HPS lamp and the plant canopy?
There is no single distance supported for every setup here. Follow the lamp and fixture manufacturers’ guidance, then assess how plants respond and adjust cautiously. Account for the fixture, ventilation, and canopy conditions, and avoid letting foliage contact the lamp or fixture.
If guidance is unavailable, ask the manufacturer rather than guessing.
How should I manage heat and ventilation with a 1000-watt HPS grow light?
Plan for heat management before installing the light: follow the fixture manufacturer’s ventilation and clearance instructions, keep the area unobstructed, and monitor the growing space and plants during operation. Do not rely on wattage alone to predict room conditions. If temperatures remain unsuitable, adjust the setup or seek qualified guidance before continuing.
Can I use a double-ended HPS lamp in a single-ended E39 fixture?
Do not treat the formats as interchangeable. A double-ended lamp requires a fixture and ballast that explicitly support that format, while an E39 lamp is single-ended. Check the product and equipment documentation for compatibility before ordering.
The listed double-ended options are not substitutes for an E39 lamp unless your equipment supports them.
Should I choose a bulb or a complete ballast-and-bulb system?
Choose a bulb when you already have a compatible ballast and fixture; choose a complete system if you need both components together. The UltraGrow Classic listing includes a ballast and bulb, with dimmable settings from 600 to 1,150 watts. Check its input-voltage options and confirm compatibility with your setup before deciding.
Final Words
For a compatible single-ended E39 setup, the GRUOTVSZAK two-pack is the leading pick, with stated 1,950 μmol/s PPF and useful longevity claims. Choose iGrowtek or YauldSun if your fixture supports double-ended lamps, or the UltraGrow system if you need a ballast and bulb together. Growlite is an option for its stated PPF and ANSI S52 specification.
Confirm format, ballast, and electrical compatibility before ordering.
