            Comments about RadioShack 10mm Ultra-High Brightness White LED:

            About John from CT's review, assuming he is not trolling the site and legitimately was trying to get some LEDs working, I'll give a reminder about light.

            Firstly, humans can see neither ultraviolet nor infrared light. Those LEDs were worthless to him if he was genuinely trying to illuminate something.

            Secondly, it sounds like he put too much current on the LED and blew it out almost instantly, which is hardly the fault of the part.

            This little LED is definitely more than bright enough to blind you for a few moments, but bear in mind it has an INCREDIBLY small viewing angle. If you need a miniature spotlight, this is what you need. If you need a miniature flood light, look for the small square LED instead.

                  Comments about RadioShack 10mm Ultra-High Brightness White LED:

                  Used as Fender lights on My Can Am Spyder. Operated off 13.8 Volts dropping 10.6 volts (( R = E/I where R= resistance in ohms, E= volts to be dropped across the resister, and I= current in Amps) to get the 3.2 Volts at 30 MA or 0.03 A ) comes to 353.333 ohms so use the next higher standard value resister 360 or 370 ohms. the wattage is calculated by (E X I) or 10.6V X 0.03A = 0.318 watts so use a half watt or higher! its simple to calculate anything using OHMs LAW.. also LEDs are Diodes and must have the proper polarity applied. sorry for the length of this but from some of the other reviews some people need help with making LEDs work. These are great LEDs!

                      this is a good led with proper voltage and install fixture will work for many years. got my leds back in 2009 still going strong . on all night every night.

                      these require 3-4 volts dc to work. also you must use a resistor to limit surge current. a 3 volt flashlight set up will not work. you must have 6 volts or more so the droping surge resistor limits current flow and drops voltage across the led to 3-4 volts. I used 12 volt supply then installed a droping resistor of 470-530 ohms this works great ..

                      I love this LED. It was used for my first Arduino 'blink' program. I just had to hook it up with a resistor and plug it in.
                      I'm planning to use it to shine light on the ground between two photoresistors for a line-following robot.

                      Note that looking at it head-on HURTS!

                        There is nothing wrong with this LED. Don't think about this for illumination because the viewing angle is so small even though it has an outstanding mcd rating. Nothing else needs to be said. Get this if for some reason you need to brightly light up a little area with a circle of light. (You could use this in a flashlight, but still take in the low viewing angle)

                          Nice bright (painful if viewed straight on at full rated current) focused spot. Using as an indicator but would be great as the bulb of a home-brew flashlight.

                                Judging by the photo of the 276-005 White LED, the stated 10mm diameter looks correct, however this would be a T-3-1/4 bulb, not a T-1 bulb as stated by Radio Shack. Also, I note the viewing angle is only 10 degrees. Although the 28,500 mcd rating looks impressive, this does not translate to a really impressive lumens rating, since the viewing angle is so low.
