5MM ULTRABRIGHT BLUE LED, BLUE OFF-STATE

I recieved my order in 2 days, which is super fast. These LEDS are really, really bright. Much brighter than the $.75 I got from my local radio shack. So bright I wouldnt look directly into them.
Unfortunatly there was no voltage listing on the package. I used 2.5 Volts.

small blue glass globe, size of a baseball. Led deffective,base unit uses 1.5v AA with solar panel, and special ckt to power led. Took a chance on this led,but this led is working out great !!

People, you MUST use a limiting resistor in series with any LED. It is NOT a voltage device. You cannot willy-nilly apply a voltage and expect it to work. It is NOT a light bulb. If you push too much current through it (more than 50 mA) it will cook the diode. They really want 20 mA or less. E = IR. Do the math, and use a dropping resistor in series to limit the current. EDITORS NOTE: In our spec sheet section is an LED HOOK-UP Guide to help figure current limiting resistors. The link is http://www.allelectronics.com/spec/LED_Hook_Up_Guide.pdf

Can anyone tell me why mine is not working. I have tried 3 and 6 volts. None work. WHY!!!!! Editors note: Remember, LED's have polarity. Are the plus and minus correct?

For a detailed look into figuring how much current a certain value resistor has, check out my post under LED-110.
