cheap LED sources
I've been looking for a good source for cheap LEDs for a project I'm working on. I want to replace 14 different 60W halogen bulbs with home-built LED lights. The reason for home-built is that the halogens burn out like crazy, but the light fixture looks nice, and isn't going to be replaced. The halogens put out an estimated 500-700 lumens (from the google research I did)
I'm looking for the best deal for white leds per lumen. the best deal I've found so far is:
at .021cents/lumen from the brightness calculator http://led.linear1.org/lumen.wiz
but considering the quantity I want.... there's not even enough room to fit those LEDs on the fixture (due to the large case size)
or if I buy 1000 of them (about the quantity I'm looking for) I'd be getting a slightly better deal, but still coming in at $120, not to mention they still don't fit.
The physical space for the leds is a cylinder with a diameter of about 30mm and a height of about 70mm.
Any Ideas/suggestions for cheap white LEDs?
