Which 500 watt CMH bulb is right for me?

Since CMH is a full spectrum lighting technology, you don't need to overthink which bulb you want too much. If you are using it for specifically veg, you'll want a high color temp (kelvin rating), somewhere around 4,000-4,200K. If you are just using it for flower, consider a lower kelvin rating, somewhere between 3,000-3200K. We also offer a 500w CMH bulb rated at 10,000K.

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