CMH and Agro quick question

Can I use any kind of Philips cmh or does it have to be a specific model. I was thinking something like the mogul screw in 400w master color ceramic metal halide hps retro white. If I can't find the right cmh then I was going to look into agros. And as stated above does any model agro work? And is Phillips 430w agro son a good choice? And buying online isnt out of the question but I'm trying to be steathy so in store would be ideal

The agro elite(315w cmh) is hard to find and big $$$$$$$$, have to buy the whole system together(ballast/reflector/bulb/lamp cord) as of now. only runs on dedicated 220v line

philips master color is being discontinued , get the all-start 330w cmh

Can buy them at any electrical supply house (cash) or online http://alldaylighting.com/product-category/hid-light-lamps/ceramic-metal-halide-lamps/philips-ceramic-metal-halide-lamps/philips-cdm-allstart-lamps/ get the clear obviously, very good bulb for the price...ONLY WORKS WITH A 400w MH MAGNETIC BALLAST

happy shopping
