Our 4200K lamps have been tuned to offer a superior spectrum of light for vegetative growth, with abundant blue light to promote tight internodal spacing during the vegetative cycle.
Experience 5 years of high performance from these bulbs when driven by our low frequency square wave ballasts under normal conditions.
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 4200K Bulb
This bulb is compatible with standard DE reflectors. You may upgrade your current bulb to CMH without purchasing a new DE reflector if desired.
These bulbs are intended for use with low frequency square wave ballasts. Although this bulb can be powered by some 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.
