Smaller LED 12 Volt Chip For DIY ?
On the surface this thing looks like a cutie. Available in (3) color temps, reasonable wattage to make rational heat-sinking area a reality, and it's the latest technology from CREE. I have big hea...

Fixed link. Tempting gizmo.
If (or when) the $40 lamp on my $10 thrift store 8mm movie projector dies, I might see about cobbling something together based on this or something rather similar. It might even end up being brighter overall.
That little "pea shooter" isn't enough light to get an image to show on a 8mm projector..
I used this 50W LED..

And that still is not as bright as the original 80W incadenscent light.. And when you get into high power LEDs like the one I showed you BETTER have a massive heatsink and decent fan to keep it cool..
I have to take a few photos of my super 8mm projector LED conversion, pretty cool..
As an additional note, the CRI on these high power LEDS is awful, I found specialized lighting gel filters which are designed for LEDs which get the CRI under control for your eyes.. But cameras are not fooled, have to really play with the white balance..
The big drawback of the LED I used is it needs to see at least 30V DC just to get a glow and to get to full brightness it must have 36V DC..
Mexs version should work on 12V though, I also have a smaller 10W version which does work on 12V, makes about 800 lumens.. Still needs a heatsink though..
