congrats captain. look forward to the other grows.
Just read the entire thread and now my gears r churning. Thnx for inspiration CM! Since those Crees send out a lot of side lighting I'm wondering about a vertical set up. Now I might not get those Area 51s. Hmmmm
Well I went out and bought 4 5000k A19 Crees and absolutely hate the side reflection. Feels almost as bad as CFLs. I think ideal uses would be reflectors and/or hung vertically inbetween plants so no light is wasted. I would love to supplement the Area 51s with these bulbs. Huge potential there. +1 on the reptile bulbs CM.Do the math. Unless you are doing a small closet grow (< 2 x3), the A51 is a bargain when you factor in all aspects, including warranty. But you can DIY an inexpensive glow/clone set up, and save the bucks for a superior flowering panel. Still, no one is a bigger fan of what cap has done than I
Yeah.Sorry for being a complete idiot, but has anyone removed the glass domes from these things?
Voids the ten year warranty, possibility of damage to LED and/or phosphor upon disassembly.I assume everyone should do this? Any reason NOT to?

Actually removing the bulb does not necessarily void your warranty since the bulbs have a tendency to get hot and the adhesive then breaks down. Basically people who've mounted them upside down have had the globes slip off. CREE knows about it and says all you have to do is bring it into any Home Depot for a replacement. I'll be exchanging one I fried recently, (shorted it against my ghetto reflector), pretty soon. So just hold on to your globes and if you ever mess one up just crack a globe and take it back, though of course you do need to mind the diodes when removing the globe.Voids the ten year warranty.....

That page and teardowns on youtube show what look like XT-E LEDs, but mine are half as many LEDs and are square. Do you know which ones they are? Also the circuit board is different.
It looks like it might be these?

or possibly the G version. I wonder how these compare to the older version.
