How long before they make these in 600w?Yes, they can only be used in a magnetic hps ballast. 400 watt is as large as they make at this time.
Dont know if they ever will. They are not marketed as an agricultural bulb. 600 watts is not common place in commercial lighting. The 400 is one bright light! Sunglasses for sure.How long before they make these in 600w?
i just read the page of the link it seems great bulb,but one thing i don't understand is it says the temperature is 4k,i don't know what this means is that hotter than a sodium bulb bcos i heard halide bulbs are too hot,any thoughts?You should look into the new CMH. Heres a link: http://www.growlightexpress.com/ceramic-metal-halide-bulbs-9/mastercolor-ceramic-metal-halide-400-watt-79.html the color spectrum is amazing. One bulb start to finish. And very affordable.
