I love me cmh fer sure...but I do like the hps and predominantly cmh mix for flowering thoughCmh rocks. Hps blows donkeys. I would go with cmh and or led over hps any day. Leds produce heat above the panels. Hid produce heat below lights into the canopy. Hps causes light bleaching the most. Been trying to sell my 1000w for a while. No one wants a 1000w.
If you talk to Thomas you get good service and unbeatable pricing ...well I deo anyways...lol...he's advanced's owner...lighting supply in Michigan has a good deal on them as wellwith the 330's only mh mag, get them here

advanced tech has good info but they are truly idiots and don't really have a clue and have the worst customer service. It will take a month for your bulb to show up.
growers house has cheap hydrofarm ballasts. the largest wings too. the 330 has a quartz crystal coating so its rated to be in an open reflector .
Op, 600w HPS is pretty hard to beat, $225 with ballast and reflector. Add some deep blue LED and you will get incredible buds.
PetFlora. I have been using a household LED bulb to grow some Aloe. I shattered the globe to try and increase the lumens. It worked great and would work even better on yours since they are frosted glass.
I wouldn't bet the farm on them yet! Every thing I have read from many manufactures shows real promise but there not quite there yet. Even this link states that if the color yellow isn't a problem to still go with HPS. For the price right now I will stay with HPS...but it looks like, for not much longer.all the info in in that link...you can use either an hps or mh mag coil ballast with them...best spectrum available period
Those are the old bulbs not designed for horti which I use and IME blows all hps away. Here's info on the new lamps. Which are developed for horticulture.I wouldn't bet the farm on them yet!
