They do , in Tennessee and Michigan . QB 288 unfortunately is a branding name used across many chinese board clones. I would suggest hardwire solder to pad.not a single person said its HLG. Besides that, their Boards are also made in China, who knows, maybe the same factory. Theyre using more expensive 660nm solutions. I dont even know, if they ever had LM281B+ boards. Total cost of this lamp is less than 250eu.
edit: they assemble in USA, but i dont think they print the PCBs on their own.
Tin the lead of your strand wire like youre supposed to. No longer a strand wire.never use standard wire? Im using AWG 19 copper cable. Its many fine copper strings, that makes it difficult to apply force. what wire should i use? I think ill just secure every connecting with a tip of transparent silikon. Probably not the only good reason. Still wondering what im doing wrong.
yeah i had that in mind as well. But couldnt find my soldering stuff and hardwarestore was about to close, so i bought 2m of a thick cable with 3 solid wires in it.Tin the lead of your strand wire like youre supposed to. No longer a strand wire.
I call BS.not a single person said its HLG. Besides that, their Boards are also made in China, who knows, maybe the same factory. Theyre using more expensive 660nm solutions. I dont even know, if they ever had LM281B+ boards. Total cost of this lamp is less than 250eu.

edit2: hope im not telling BS here XD
Well they're the ones with the Quantum Board patent.theres no data on this LM281B+ boards, is there? I mean complete board, not just the Lm281B* SE rank datasheet.
edit: yeah i was wrong with HLG but i didnt want to edit my comment or delete it, would have looked cowardish.
But HLG wasnt the first to have the idea to put some LEDS on a board instaed of a strip?
Do you have any evidence that someone came up with the QB288 idea before HLG did, or is this just some speculation on your part?theres no data on this LM281B+ boards, is there? I mean complete board, not just the Lm281B* SE rank datasheet.

165 lumens /watt, not counting driver losstheres no data on this LM281B+ boards, is there? I mean complete board, not just the Lm281B* SE rank datasheet.
