Dudes trying to get me to sell their qb light kits. Offered me a price that won’t have me setting up shop any time soon, but he definitely ensured my next order is with him. But I kind of feel guilty. Like should I at least try to share the discount offered to me? Like 240w for 120, 320 for 175, and 480w for 236. But I’d pay shipping and that makes it not worth it fr. But damn, what would you do?
Yeah? For me shipping was a bitch. $80 for 2 240w 288 kits. But from the time I bought my lights a few months ago til now the prices dropped as far as what dude sent me, but his mini site surely increased lol right when hlg dropped the rspecs lol
LM301H isn't any more efficient you're just paying for die stability via an enhanced silicone die covering. Meaning it is more stable to lumen maintenance and moisture with foreign chemicals which could be as simple as finger oils or rubber you've touched. A lens would fix all that or a conformal coating. I think Samsung was targeting Fluence and HLG with LM301H
Oh yeah def cool and can't hurt to have it but as long as you take care of your exposed boards there's no rush to upgrade to them.
have u seen these? Invisible Sun R Strip they in the UK though and kinda expensive imo. Also they have far red in there idk lol
No but I just checked them out. They look pretty cool. I like the mounting holes on the side. I probably would have done like a 5:1 DR to FR based on white papers I've read but I'm guessing they did a 2:1 because they are power dense chips and wanted to balance the board output.
Upgrading from blurple, I could use an LED expert to help me get the most bang for the buck choosing between those options. This will be going over a 4x4 no-till bed inside a 6.5x6.5 tent. I was going to fill with a few cxb3590 and exotic mix (uv/ir) or just grab 2 from this list. About the lm301h, is there really no added efficacy or just a few marginal percent like the difference between lm301b and lm561c? edit: added lm301b 3500k+CREE XPE 660nm $437 to list
I've been trying all night to get any data from Kingbrite to compare those models and so far all I've received is PPFD chart showing two distances and nothing else (including which product it was actually referring to...)
I'd stay away from IR/UV if you're going back for your buck. I looked up the Epistar chip and can't any information on efficiency. I think this is the chip based on 660nm and being of any power significance. https://www.epistar.com/Upload/Led/all_product_caty01466564788.pdf So I can't tell you whether to go Cree or Epistar. I will say Epistar is not that bad and you're fine having it in your products but what I can't say is if on such a specialty color they have the same efficiency.
I would also second niemiled.com, they have great lights and I personally use their 260w LM301H quantum board
