Based on the fact the the seller is aware of this thread and he knows that you're the op, I'm pretty certain you'll get those c diodes.Now let's see if that's what I really get.
Haha! He's crapping himself. I reckon he's got a whole pile of those "LM561C S6 Bin" boards with B chips in them he wants to flog off to unsuspecting hobby growers - which he's probably already done - but has been caught out and realised that word of mouth spreads far and wide on the internet . . . Far and wide enough to affect his future business.Got an email from Jeff. New boards will ship in the next few days. He attached a picture of the new boards. Like that means anything. But here they are. I'm going to build another 4x4 light to place on the other side of the 4x8 tent. I'll post PPFD results from both sides.

i'm not sure, i know you can have boards custom built on order but he probably also does have some boards prebuilt as they sell them on their website too. either that, or he just has a pile of lm561b diodesAre the boards from Jeff build to order though?
is that an e-mail you received from jeff or something? are you saying he doesn't have any LM561C?old mother sativa

"You have some of these coming? Good thing we have this place to police what he's selling."
>i am still waiting for actual 561 c's...they had to be ordered last month and will here early jan
i expect them to be 561 c..and apparently they never have them in stock
>mine are built to order and new designed pcb
BUT..you are correct..about this forum..good thing..

i guess cobkit will be comparing to a QB with top bin 561c, that will be interesting
>>>yes..thanks to him and everyone here
have you tried those particular boards with a different driver to test that's faulty? or maybe the 2 boards with a different board each to try determining which one it is?Also, I have eight of these boards running on four Meanwell drivers. So every two boards have one driver. I have one set of lights that turn off after about five minutes. Doesn't matter if I run them hard or turn them down. Any suggestions?
Also, after having these on for a few hours on full. Boards don't get hotter than 115F without a heatsink.
Haven't tried that. Spent so much time getting them just right I don't have the energy to undo things right now. Heading out of town tomorrow morning and will, for the most part, be gone until after the new year so this project will have to be on hold for a bit. If it turns out I have a bad board I may have to keep the board I had reserved for @CobKits.have you tried those particular boards with a different driver to test that's faulty? or maybe the 2 boards with a different board each to try determining which one it is?
