      That moment when you realize you could power half a display case of lighting off a USB port. The efficiency of modern LEDs is impressive.

      504 LEDs @ 500mA total, in strings of 2 (~8V) ≈ 2 USB ports worth of power with voltage to spare.pic.twitter.com/s58ckZkxzF

      Nice setup, but I'm a bit leery of the colour temperature there.

      And this is why the LEDs are bicolor (warm/cool) and thus allow for color temp adjustment. I just need to make a controller :)

      Oh, clever. Best thing, though, is there's no UV like you get with flouros, so no dye breakdown.

      Yup. Also I have them broken out into 24 channels so I can individually adjust angle of lighting per shelf too.

      Nice. Got any photos of how you've got it all set up or similar?

      There are some photos on @marcan42x but writing up a proper explanation is on my TODO list (got some making of photos stashed)
