I am running two evergrow A4's and a reefbrite XHO blue over my 150 and enjoying them so far. might even add more down the road.
My experience with Chinese products in general is that they most of the time of better value than the competition and also of a lesser quality and durability.
Since these types of lights are supposed to work for a very long time and there are no long time owners I'd think it over very carefully before choosing them over the US or European counterparts.
Well if the bulb breaks, then buy another. @ $35 its a little more expensive then an MH bulb but without the equipment required to run an MH (ballast, chiller etc). Either way you save, even if you have to keep a few laying around.
I am using PAR 38 bulbs so far I only have 20K+440nm. My monties have been growing great under these. My monti cap put on roughly 3/4" of growth in one month.
Ordered some 15k+20k+440nm bulbs not too long ago, still waiting for them to get here.
$35 .ea for 12chip bulbs
$25 for my 15chip 6500k bulb
