      Comments about RadioShack 5mm 880 MCD Blinking LED:

      I use these for making pseudo car alarm warning systems. Start with a RS 2-cell AA battery box, drill a small hole (about 3/32") in the top end of the battery box and add a dropping resistor. Remember, from your physics class V=IR...with V being the two AA cells (3.0 volts); I being 35 milliamps (0.035 amps) and R being the value of the dropping resistor (86 ohms...I used 100 ohms). Get the polarity right or it won't work. Secure resistor and wires inside the top of the battery box with silicone adhesive. Be sure the box isn't sealed so you can add new batteries (they last over a year) Mount to the inside of car with Velcro and it's portable!

      Comments about RadioShack 5mm 880 MCD Blinking LED:

      Use on model railroads for strobe light. The duty cycle is about 25% on. To increse view angle: Take a fine file and file off the dome on top. Careful, don't go down too far. You will now have about 130 degree view angle. Want more? file around the outside, just enough to frost the plastic and you get about 230 degree view. This works on most LED's

      Good Blinking LED

      By Dan / ABØRE

      from Marshall, MN

      Verified Reviewer

      Comments about RadioShack 5mm 880 MCD Blinking LED:

      The previous reviewer mentioned this LED is 3.0V typical, 3.8V max. I'd like to add it is rated at 35mA max current and 880mcd brightness. (Radio Shack offers another blinking LED, p/n 276-036, but that one is a bit of a power hog with an 80mA rating.) This LED has a viewing angle of 20 degrees (meaning it is half as bright at 20 degrees off the direct viewing angle).

      I used one of these LEDs to make a simulated security alarm for my car, using a 330ohm dropping resistor to protect the LED. Despite the somewhat limited viewing angle of the LED I've found this LED is relatively bright in all directions and works well for my application. The LED blinks ~1x/second, give or take, which is just right. I found the actual current consumed in my application jumps between 19.5mA and 27.5mA, which is not nearly enough to run my car battery down.

      To determine the appropriate sized dropping resistor for your application, take Supply Voltage minus LED Voltage divided by LED current. So in my case (14.4V - 3.0V) / .035A = 325ohms, rounded up to next highest value of 330ohms (I'm using a 1/2W resistor). Note: there are 1000 milliamps in an amp, so 35mA is entered as .035A.

      Overall this LED is a great value for the price paid. Using this LED is much easier than designing and building an outboard circuit to control the flashing. Having the LED stocked at my local Radio Shack was the icing on the cake. This is one of Radio Shacks better products and I hope it stays in their product line permanently.
