Yeah philips cmh bulbs are really tough bulbs/ ah those in the link(850w) are the energy advantage bulbs(very good) I use the 330w/205w versions of that, they ONLY run on MH magnetic ballasts but are better than their hps versions due to more lm/w(higher CRI) and less electrical draw with a longer useable life.....I buy mine at the local electrical supply store for $58 for the 315w bulb but you can buy them here if you want
http://advancedtechlighting.com/cdmallstart.htm great info on these.....and they blow away the hortilux blue for half the price....oh and it's open fixture rated unlike the horti and most mh bulbs/ even GE cmh need to be in closed fixture, robbing you 15% output.
the new 315w agro elite is a different beast.......uses a digital ballast/can be dimmed/ less draw than the older ^^versions but puts out way more red/less yellow and green (which we want
)
Cycloptics technology makes advanced vert reflectors and makes a complete package(all bright) with the new philips cmh bulb/ballast/reflector.....not yet for sale for consumers(sucks)
www.gel.usa.....which makes the ceramatek ballast packages, includes the bulb/ballast and lamp adapter(too fit standard mogul bases)....no reflector( can go bare bulb if you want) and no mogulbase/cord to plug into the ballast ( I think, you need to contact them for specifics).....which should be for sale any day now/ ill know more when I get a reply to my email.....
Pinball wizard's cmh grow was not a specific thread(that's why I guessed his strain) but rather he posted pics of it and small info in the huge cmh thread at ic@mg around pg 285-286........
....ha I still have this pic on my phone when my PSU grow buddies called me a liar about an MH version of the philips cmh existing.....I mass texted this to the pricks
this is the 205w version that outperformed our horti blue 400w mh(we love new tech/experimenting with it lol).........wow long reply, bored in FLA till the bars fill up.......good luck and hopefully ill get some pussy down here
