If you grow with 100w Ceramic metal halide (CMH) lights, you'll eventually need a replacement 1000 watt CMH bulb.

Which 1000 watt CMH bulb is right for me?

Here at Hydrobuilder, we offer top of the line 1000w CMH bulbs from the most reputable companies, such as NanoLux and Grower Choice. CMH is a full spectrum lighting technology, so you don't need to overthink which bulb you use. If you are using it for specifically veg, you'll want a high color temp (kelvin rating), somewhere around 4,200K. If you are just using it for flower, consider a lower kelvin rating, somewhere between 3,000-3200K.

Looking for a different wattage? You can shop all CMH bulbs, as we have them ranging from 315-1000w.
