Elite Lighting 1000W DE Dual Spectrum Lamp - Double-Ended Lamp for 400V Fixtures
Best for: growers running a double-ended 1000W fixture who need a dual-spectrum replacement lamp for veg and flower.
Our thoughts
This is a double-ended lamp, not an LED fixture, so make sure your ballast and reflector are DE-rated for 1000W at 400V before you buy. Once fitted correctly, DE lamps run hotter and brighter than single-ended equivalents and spread light more evenly across the canopy, which is the whole point of stepping up to a double-ended setup. Dual spectrum means one lamp covers both veg and flower, so you're not swapping bulbs between stages.
The Elite Lighting 1000W DE Dual Spectrum Lamp is a double-ended (DE) grow lamp built for use in 400V DE fixtures. Double-ended lamps run current through both ends of the bulb rather than one, which spreads the arc and light output more evenly than a single-ended lamp of the same wattage, and typically runs more efficiently as a result. The dual-spectrum formulation is designed to support both the vegetative and flowering stages from the one lamp, so you don't need to switch bulbs when your plants move into flower.
Fitting it correctly matters: DE lamps need a DE-specific double-ended fixture and a matching 400V DE ballast. It won't work in a standard single-ended (mogul base) reflector or ballast.
How it compares
DE lamps are the step up from single-ended HPS and CDM setups, and this sits in that established category.
- Like well-known DE lamps from Lumatek and Eye Hortilux, it's built for the more even, higher-output light spread that double-ended fixtures are chosen for over single-ended kit.
- Fixtures such as the Gavita Pro 1000e DE run a similar double-ended format, so this lamp is a straightforward drop-in for anyone with a compatible DE ballast and reflector already in place.
- Being dual spectrum, it saves the cost and hassle of buying separate veg and bloom lamps that some single-spectrum DE options require.
You're getting the double-ended format and dual-spectrum coverage that pricier branded DE lamps offer, at a more accessible price point.
Usage guidance
Getting the fixture right matters more with DE lamps than with standard single-ended bulbs.
Fixture compatibility
Only fit this lamp into a double-ended fixture and ballast rated for 1000W at 400V. Do not attempt to run it in a single-ended reflector or ballast.
Handling
Avoid touching the glass with bare fingers, oils from skin can cause hot spots and shorten lamp life. Handle by the base or use a clean cloth.
Hanging height
Start higher in the canopy than you would with a single-ended lamp of the same wattage, given the increased output, and adjust down gradually while watching for heat stress on the top leaves.
Lamp life
Like all HPS-type lamps, output gradually drops over its working life. Most growers replace DE lamps annually or after roughly 10 to 12 months of regular use to maintain yield.

Our take
If your fixture and ballast are already DE-rated, this lamp gives you the double-ended output and dual-spectrum coverage that setup was built for, without paying premium-brand prices for it.
Worth picking up if you want dependable double-ended lighting without the flagship-brand mark-up, just double-check your ballast and reflector are 400V DE-rated first.
