That’s a pretty good thread, and also reveals that there is an existing single-component solution for the scheduled dimmer potentiometer, from the aquarium sphere, which I hadn’t thought of at all. A hundred bucks is a bit more than I was hoping to see, since you still probably need one for each room, but at the very least it simplifies things for the early adopters.
I thought the strips seemed pretty attractive for people making their own setups, since they can passively cool and are already somewhat diffuse. I do think the intensity is plenty high enough (20,000lm in a 56x26cm board), but these Bridgelux COBs the fellow mentions are 10-15% as expensive per lumen as the Optisolis strips, and outperform them too, at least according to their own measurements. As he says, it’s not much more complicated electrically to set them up, but you do have to fasten them to a heatsink with thermal paste, and possibly mount a reflector, which makes things somewhat more tedious. Overall though, even with the expensive controller, a 20000lm device is probably still coming in under 200 USD for materials (not including however you mount it in the space), which is pretty similar to what you get out of the Hue bulbs.
Yeah, that’s useful. Agree on the assessment, I want to give it a shot with one of those Bridgelux Vesta Thrive thing, it sounds like a good hobby project I would like to try. If that happens, I would do a post about it here.
