Super Bright - Great for illumination!

Reviewer: A viewer from GARFIELD, NJ USA

These LED bulbs are intended for illumination, so they are extremely bright and cast light over a very wide angle.
One caution though. They don't have current limiting circuitry included so DO NOT connect them directly to a power supply or battery. Will be using these bulbs and a few other parts from all electronics to make a homemade solar powered shed light.

Current noted

Reviewer: A viewer from OR USA

I put a 50-ohm resistor in series with the -248 and got a current of 200mA at 14vdc. With the same resistor, I put 2 of the -248s in series and got a current of 160mA. All seemed to produce the same brightness- a lot.
