Looks dangerous lol, like a virus capsid. There's a ton of 23W bulbs out there...i like this one: http://www.extremetech.com/electronics/128669-philips-new-100w-equivalent-led-bulb-runs-on-just-23w. I use these: http://www.amazon.com/Philips-100w-Engergy-Saver-Flourescent/dp/B0055OCN8I.
Pretty sweet shit if you realize how much 100Watts of power actually is. -80W per bulb is a massive savings, especially on a large scale.
Yeah, was about to say the same thing. Got a LOT of hits on eBay when looking for bulk high power UV LEDs this week (blacklight is NEVER overated)
And plugging a bunch of serial groups of 10 groups of 3 LEDs in serial on 12v is the same as 1 group of 30... on 120V. The difference is that the bunch of groups will run a lot hotter (more current, that is what cause heat).
