Ordered one last night on amazon

Popped it in the middle of 4 single ended phillips bulb and I'll say she is bright as fuck about the same heat and looks to throw the light quite a bit more than the growers choice and sun system hoods I currently have.

Has anyone done a GC bulbs vs phillips side by side?

Philips is the largest,most advanced lighting manufacturer in the world,they invented the 315.
Growers choice is a small import co using Chinese manufacturers and selling to the Canna industry only.
I'm not knocking growers choice,more power to them but comparing the two is really not fair,millions of sq ft of manufacturing and R and D facilities all over the world run by the best scientists in the industry vs a 4000 sq ft warehouse with a dude on a forklift that distributes knock offs?Philips would control everything but for the fact that they want nothing to do with the Canna industry.
