One of them had a little problem.. Should be repairable..

But the specs (on the two good ones) aren't what I expected..

They said..

* Voltage: DC 8-30V
* Power Consumption: 3 Watt

So, I was thinking maybe 1.5 watts at 13 volts.?.

Nope. At 13v, the flow is 66 ma.. 0.066A x 13v = 0.86 watt..

So there shouldn't be a problem if I forget to turn one of these off at night..

Maybe if I use a full 30v, the flow would kick up to 3w.. As the lifespan heads down hill..

Even at less than a watt, they feel warm. About 90 deg F in a cool basement..

I used a fuse holder to test them one at a time.
Later, I'll cut off the car lamp adapters and wire them all in parallel
and see how much light they can provide (as a group) in a dark room.

Maybe I can get near 3 watts! (Using all three lamps)!

I'm not too encouraged, since my cheapo 3AAA LED flashlights make these things look really weak..
