Omega 1000w DE Metal Halide Grow Lamp - Full-Spectrum 1000W CMH Lamp for Veg and Bloom
Best for: growers who want a full-spectrum, closer-to-daylight light source for a 1000W 400V DE fixture, especially through the vegetative stage.
Our thoughts
To be clear, this is a ceramic metal halide (CMH) lamp, not an LED - it's a bulb that goes in a compatible 1000W 400V DE fixture, and it earns its place because the spectrum genuinely looks and behaves differently to a standard HPS. The blue-leaning full spectrum makes for tighter, denser growth in veg, and it's a straightforward way to add that spectrum to an existing DE setup at a low price.
The Omega 1000w DE Metal Halide Grow Lamp is a double-ended ceramic metal halide bulb rated at 1000W and 400V, designed to fit any compatible 1000W 400V DE fixture. It runs a 6400K colour temperature, sitting high on the blue end of the spectrum, which tends to encourage shorter, denser vegetative growth compared to the red-heavy output of a standard HPS lamp. The result is a light spectrum that's noticeably closer to natural daylight than typical high-pressure sodium lighting.
Inside, it uses two ceramic arc tubes designed to keep light output consistent over the lamp's life, with air purification chambers built in to improve PAR output and reduce the striations and hot spots you sometimes get with cheaper metal halide bulbs. It carries a CE mark and a minimum one-year guarantee.
How it compares
CMH/metal halide lamps sit alongside HPS and LED as one of the three main lighting types used in DE fixtures, each with a different spectrum trade-off.
- Compared to a standard Omega 600w Dual Spectrum HPS lamp, this CMH bulb runs a bluer, more daylight-like spectrum better suited to veg and structure
- Against premium ceramic metal halide bulbs from brands like Philips or Sylvania, this is priced well below what you'd typically pay for a 1000W CMH lamp
- Compared to LED fixtures of similar wattage, CMH lamps produce more radiant heat but many growers still prefer the spectrum quality for certain growth stages
If you want a genuine full-spectrum CMH option for a DE fixture without paying premium-brand prices, this delivers the spectrum benefit at a fraction of the cost.
Usage guidance
Compatibility check
This lamp only works in a 1000W 400V DE fixture with a matching digital ballast - it is not interchangeable with single-ended (SE) HPS or CMH fittings.
When to run it
Many growers run this lamp through veg for the tighter, bushier growth the 6400K spectrum encourages, then switch to an HPS lamp for flower - though it can be run through the full cycle if you prefer a consistent spectrum.
Handling
Let the lamp cool fully before handling or removing it, and always switch the ballast off first - like all HID lamps, it runs at high temperature.
Technical specifications

Who this is for
- Growers running a 1000W DE setup who want a full-spectrum alternative to HPS
- Anyone chasing denser, more compact vegetative growth before switching to flower
- Growers who want CMH-quality spectrum without paying premium-brand lamp prices
Best suited to growers who already have a compatible 1000W 400V DE fixture and want to experiment with spectrum.
Our take
This is a genuine full-spectrum CMH lamp, not a re-badged HPS bulb, and the twin ceramic tube design and air purification chambers are real engineering rather than marketing fluff. For the price, it's an easy way to add proper daylight-spectrum lighting to a DE rig.
Does exactly what it should, day in, day out - a solid, low-cost way into CMH lighting if you're already set up for 1000W DE.
