The Adjust-A-Wings Hellion 630W 4200K DE CMH Lamp is a professional double-ended ceramic metal halide lamp delivering approximately 1210µmol/s of broad-spectrum plant light with a high CRI of approximately 97.
Developed specifically for high-performance plant lighting, the 4200K version produces a broad, daylight-style spectrum with a substantial blue component alongside useful red and far-red wavelengths. This makes it particularly well suited to propagation, vegetative development, mother plants and mixed-spectrum lighting installations.
Unlike conventional HPS lighting, CMH technology produces a much broader spectral distribution. Adjust-A-Wings developed its DE-CMH lamps using Japanese ceramic arc-tube technology to provide high output, excellent colour quality and a spectrum designed specifically around plant development.
This is a 630W double-ended CMH lamp and requires a compatible 630W DE-CMH fixture and suitable low-frequency electronic control gear. It is not interchangeable with standard HPS, metal halide or E40 lamps simply because they share a similar wattage.

4200K broad-spectrum CMH lighting
The 4200K version of the Adjust-A-Wings 630W DE-CMH is designed around a cooler, daylight-style spectrum with considerably more blue light than a conventional HPS lamp.
This makes it particularly useful during propagation and vegetative development, where strong blue-spectrum availability can support compact, controlled plant structure and vigorous foliage development.
The output is not limited to blue wavelengths. CMH technology provides a broad spectral distribution extending across the visible spectrum and into useful UV and far-red regions, producing a much more balanced light profile than conventional sodium lighting.
Approximately 1210µmol/s photon output
The 4200K Adjust-A-Wings 630W DE-CMH produces approximately 1210µmol/s of photosynthetic photon flux, equivalent to an efficacy of approximately 1.92µmol/J.
PPF measures the total quantity of photosynthetically active photons produced by the lamp each second. For plant lighting, this provides a more meaningful indication of output than lumens, which are weighted according to human vision.
The amount of light ultimately reaching the crop as PPFD will depend on the reflector, fixture geometry, mounting height, spacing and overall lighting layout.
High CRI broad-spectrum output
With a colour rendering index of approximately CRI 97, the 4200K DE-CMH provides a much broader visible spectrum than traditional HPS lighting.
Plants under the lamp therefore appear considerably more natural in colour, making visual inspection easier while also reflecting the broader spectral distribution produced by the ceramic metal halide arc tube.
CRI itself is a human-vision measurement rather than a measure of plant-light efficiency, so it should be considered alongside PPF, spectrum and crop requirements rather than used as a standalone horticultural performance figure.
Ideal for mixed-spectrum lighting
Adjust-A-Wings specifically positions its 4200K DE-CMH technology as a strong partner for DE-HPS lighting in mixed-spectrum installations.
HPS provides powerful yellow, orange and red output, while the 4200K CMH contributes substantially more blue alongside its broader spectrum. Combining the technologies can therefore create a more balanced overall spectral profile than either source provides alone.
The lamp can also be used independently where its cooler broad-spectrum output is appropriate for the crop and lighting strategy.
Requires dedicated 630W DE-CMH control gear
The Adjust-A-Wings 630W DE-CMH is a specialist discharge lamp and must be operated with compatible 630W DE-CMH control gear.
Adjust-A-Wings developed dedicated low-frequency square-wave electronic control gear for its 630W CMH system. Correct ballast matching is important for lamp starting, stable operation, spectral performance and service life.
Do not connect the lamp directly to the mains and do not assume that a 600W, 630W or adjustable HPS ballast is suitable. Only use control gear specifically approved for the lamp type.
Lamp life & output maintenance
Adjust-A-Wings recommends replacing its 630W DE-CMH lamps according to accumulated operating time and lighting performance rather than waiting for complete lamp failure.
For installations operating around 18 hours per day, the manufacturer recommends replacement approximately every 12-18 months. Lamp output gradually declines with operating hours even though the lamp may continue to illuminate normally.
When commissioning a new lamp, Adjust-A-Wings recommends operating it at full rated power for its first 24 hours to season the lamp before using any compatible dimming function.
Installation & handling
- Use only in a compatible 630W double-ended CMH fixture.
- Use correctly matched CMH electronic control gear.
- Disconnect the complete lighting system before installing or removing the lamp.
- Allow the lamp and fixture to cool fully before handling.
- Do not touch or operate a lamp with damaged outer glass or electrical contacts.
- Ensure both ends of the lamp are correctly seated in the fixture before operation.
- Maintain appropriate ventilation and clearance around the fixture.
- Keep electrical components protected from irrigation water and excessive moisture.

Adjust-A-Wings 630W 4200K DE-CMH FAQs
What is the difference between CMH and HPS lighting?
CMH produces a much broader spectrum with substantially more blue light and excellent colour rendering. HPS is more heavily weighted towards yellow, orange and red wavelengths. Both technologies can be useful independently or together depending on the lighting strategy.
What does 4200K mean?
4200K describes the lamp's colour temperature. It produces a cooler, daylight-style appearance with a strong blue component, making this version particularly useful for vegetative development and supplementary lighting.
What is the PPF of the 630W 4200K lamp?
The 4200K version produces approximately 1210µmol/s of photosynthetic photon flux at its rated 630W output.
Can the 4200K CMH lamp be used for flowering?
Yes. Its broad spectrum can support full-cycle plant development, although the 4200K version has a stronger blue component and is particularly well suited to vegetative or mixed-spectrum applications.
Can it be combined with HPS lighting?
Yes. Adjust-A-Wings specifically promotes combining DE-CMH and DE-HPS systems where a broader mixed spectrum is required. The CMH contributes blue and broad-spectrum light while HPS provides strong yellow, orange and red output.
Does this lamp use an E40 screw fitting?
No. This is the 630W double-ended version and requires a compatible DE-CMH fixture. It should not be confused with single-ended CMH lamps that use an E40-style base.
Can I use a standard HPS ballast?
No. The lamp requires compatible control gear specifically designed for 630W DE-CMH operation. Correct ballast matching is essential for reliable lamp operation and lifespan.
Why does the lamp have such a high CRI?
CMH technology produces a broad visible spectrum, giving the 4200K lamp a CRI of approximately 97. This produces a more natural-looking light than conventional HPS and makes visual crop inspection easier.
How often should a 630W DE-CMH lamp be replaced?
Adjust-A-Wings recommends changing its CMH and DE-CMH lamps approximately every 12-18 months when operated for around 18 hours per day. Replacement timing should also take measured light output and operating hours into account.
Should a new CMH lamp be run at full power first?
Yes. Adjust-A-Wings recommends running a new lamp at its full rated output for the first 24 hours to season it before using compatible dimming settings.
Is this lamp suitable as a direct replacement for a 600W HPS lamp?
Not as a simple lamp swap. The 630W DE-CMH requires its own compatible fixture and CMH control gear, so ballast and lamp-holder compatibility must be checked before changing lighting technology.
How should a used CMH lamp be disposed of?
Discharge lamps should be handled through an appropriate lamp recycling or WEEE waste route rather than being placed in general waste.
