This 3K-Red bulb has been tuned to deliver beneficial UV as well as red and far red light to stimulate metabolic activity for prolific flowering, while maintaining substantial blue light output for healthy and vigorous growth. 


Experience 5 years of high performance from these bulbs when driven by our low frequency square wave ballasts.


Eye protection is recommended for working under any grow light, but especially CMH lamps as they are known to produce UV light that is harmful to growers! Please consider UV when selecting attire for working under CMH lamps.

630W DE CMH 3000K-Red Bulb

SKU: 0004
  • This bulb is compatible with standard DE reflectors. You may upgrade your current bulb to CMH without purchasing a new DE reflector if desired.


    Although this bulb can be powered by many high frequency (HF) sine wave ballasts, it is NOT compatible with all high frequency ballasts! As we cannot guarantee compatibility with high frequency ballasts, we do NOT recommend this bulb for growers without a LFSW or other CMH compatible ballast. If you are not sure about compatibility, please contact us before purchasing.


    Some growers have reported catastrophic bulb failure with incompatible ballasts including bulb popping! If you absolutely insist on running a CMH lamp on a high frequency ballast, please do not do so without installing a glass lamp shield, and understand that you do so against our safety suggestions.
