i feel youre losing out on that size with bulbs
Day 1 and Day 15 under 80w led panel.
Only complaint is lack of stretch, lol. But they do promote a thick canopy with little effort. Kept the lights 18" above during the first 10 days, didnt seem to matter much. Dropped back down to 12" last night, will be at 6" by weekend.

Looks cool if not a little overengineered.
Any particular reason you didn't screw those cleat sockets into a piece of wood?

ALSO, real cheap, 7 dollar 50 W full spectrum LED but it needs a US to EU converter because it's 220V driver on chip.
http://www.ebay.com/itm/50W-170-265...r-380NM-840NM-Full-Spectrum-LED-/262703085255
$6.65
if you don't have or find a good general converter/transformer this 100W one is 10 dollars (the 50w ones are cheaper but it's right at the line and so sine i don't understand the nuance there, this ones 100W)
http://www.ebay.com/itm/100W-Power-...V-240V-Up-Down-Volt-Transformer-/231169110709
$9.99
so that would be $16.64 for 50W which is pretty good.
supplementing or visa versa, with those lights and/or cree 100W(18W) 5000K could be great.
if heatsink srews are unavailable, mixing atomized copper powder with jb weld in the right ratio, like 1:1 is said to be a good LED heatsink adhesive. i did it but i didn't get the exact measurements, beause i alsorolled in some arctic silver with copper and heatsink silione adhesive which failed and gummeup on me quick, then i redisolved it in paint thiner, decanted and mixed with the jb weld and copper and just a bit of cetone to get it gummy like cake batter, and squeezed it out in lines on the heatsink and quickly (it turns out i didn't need to rush) set all the LEDs
(set off the heatsink in waiting ar the approximate spaings in rows, with the + - in the same directions)
on and left two nice big textbooks on them for 2.5 days

You cant ground wood, water with no safety return = potentially dangerous just like exposed barbs and terminals there is a lot i want to fix still but i like it

Those are pretty cool with the driver built in like that. Shame it is 220V, but still pretty cool. They are technically OTS LEDs, not too far off topic IMO.

I actually have the 110 versions ordered, in 4 color temps. I can't wait to measure their actual pull from the wall.
