those things are beasts

however - please note that these are not covered by warranty (per HLG)

was news to me, i need to update the page.

Apparently (unlike the phosphor chips we are used to), if wired backwards, all the samsung reds blow out

so please be careful when wiring - no room for error

Even though I bought a bunch of the 648 boards before HLG said no warranties, something tells me that they would still help this old person out if I have any issues (after wiring them correctly and under normal use, of course). I think it's silly not to consult the HLG website and the people here to triple check before saying, "Hold on to your butts" and hitting the surge protector switch for the first time(I had to do it, for Samuel L. Jackson's glory).

It's pretty awesome you stock them man, they look mighty fine and my peppers are loving it! Thanks for the awesome service, shipped same day and got here in one piece.

Get the 4.85 wide, it's actually cheaper than the 3.5 and has the disapation capacity you need. I built a light with a 40" slab of this running 6 Cree 2530 @ 40 watts each and it worked fine If I remember correctly heat at temp at the heatsink was 90F

I need some advice, do you think the 3.500" heatsink usa profile at 48" would be good for 5 1212's at 50w. ?

yes i accept bitcoin, by arrangement.

we need to agree on a rate and I have to know when its coming so i can turn it into cash as soon as it transfers. Its too volatile and in the past i would have people buy stuff on one of bitcoins erratic pumps and lose 10% or more by the time i could cash it out
