Check the differences in prices for dual-arc bulbs and standard bulbs...$$$$

If using a digital ballast?...you must use bulbs that are compatible with that ballast...and that's the tricky part.
Dutch Pimp Reviewed by Dutch Pimp on . Dual Vs. Single spectrum? Okay so i have been away for a while an have to change my op plans. So i am wondering has anyone use them dual spectrum lights." Runs a HPS light and a MH in the same hood" Cause i am not sure if i should go with a 800w dual spec., Or should i just go with like A 6oow Hps light and get a 600w MH conversion bulb? I am just courious if the Dual one is a better way to go. As more watts and all. But the other way its getting 200 more watts in each area.? Not to sure what to do/go with so Rating: 5
