I bought a few of these super bright LEDs off Ebay from China. $18 for 30. They are 0.5Watt, 55,000 MCD, 100ma 140 degree viewing angle. 6 of these LEDs are brighter then my 3watt flashlight with the cap off and one can light up a room enough to be a night light..

I would put it in the SANYO Envelope Battery contest but it is not a AA, AAA, C, or D.

hey thanks!<br /> <br /> good one,<br /> <br /> can you please post or upload the circuit diagram Rough one will do,<br /> <br /> on how did u connected the 3 -resistance with the LED's<br /> <br /> as i assume these are superflux/piranha LED's<br /> <br /> and are 4-pins, 2 anode and 2 cathode.<br /> <br /> Please post the diagram,<br /> <br /> Thanks.<br />
I made one with 12 regular leds... about as bright as that, if I can judge from the pictures, but I might be wrong.<br />
oh that so easy to make. i have assembled .5watts leds arrays for my old flashlights for more than 10 times!!!
so these run off 5v? or is it 3.4-3.6 like every other LED ive seen. I say 5v because the amperage is 0.1A and 0.1A x 5v = 0.5 watts, yada yada yada etc<br/>
They call them .5 watt. They are 3.2-3.6V
Okay, thx
use a 4xAA battery pack with 9v clip.
