Well the f564bs came in today. They’re not as nice as the influx strips. Composite PCB instead of aluminum. I wish I could find some strips with the 301b chips in them instead of the 561b+, simply because the 301s break 200 lm/w and the 561s don’t. Still, the 561s are a long way from sucking, and will put out more light than the cobs I’m replacing with them.
My boards and strips from Atreum have 301b chips in them but their stuff is custom. They either special order their strips on 1/8” aluminum with 301s in them or they print and assemble in house. I have not been able to find a single strip on DigiKey with 301b chips. I think Samsung mostly puts them in TV backlights. Besides, these F564 strips are way cheaper than the ones from Atreum, even after buying heatsinks.
I’ve seen a few threads on here from people that have built with these f-series strips and they seem to work really well. I’ve mostly seen people build with B24Bs instead of 564Bs. I think having 4 B24Bs on an 8” heatsink would be an awesome inexpensive large scale lighting module.
Anyway the heatsinks are coming in tomorrow but I’m not going to do anything with them until the weekend. I’m not comfortable attaching a composite PCB with self tappers like I did with the influx strips. That means doing it right — drill, tap, and machine screw. Not the same self tappers that I use for heavy gauge steel framing. Last thing I built using those screws was a SCIF for a company that makes satellite control software. 18 gauge steel studs, deck to deck all the way around. Two layers of 5/8” rock over the whole damn thing. By far the most tedious project I’ve ever done and by far the most secure thing I’ve ever built. A bank vault is more secure but not by much.
