  • Good Led

    posted by Franzel0815

    Cheap! Low power consumption Relatively easy to install (soldering skills required). Offers flexibility in terms of how/ where you wish to use it as it does not come mounted on a star. Good quality only one of the 50 is dead after a month at normal use in a living room lamp.
    A constant current source and a heat sink is required, otherwise you will fries your emitter
    If you know how to handle these type of Led, i can recommend these one (fifty)
  • Great value for the price!

    Great piezzo buzzers that are offered for a very reasonable price!
    Great for use with the arduino or other prototyping electronic boards
    I used them with my arduino. Unfortunately, there is no piezzo buzzer example included, but with a quick google search you will easily find one that works.
  • Great product for great price

  • Best Bang For The Buck

    posted by thebigkahuna

    Pros on this bulb would be that they are MUCH brighter than the typical "Ebay" bulb found which looks to be the same bulb as this one. Main difference is this one looks like it's built a little heavier duty to take the heat better. In my opinion this is the only way to go as regular led boards tend to burn out when run without a resitor (while car is on). This can take the heat and possibly be overdriven without problems.
    Nice, I can leave my lights on for extended periods of time without fearing drowning my battery (as much). These ARE the same effect as taking a cree flashlight at 75 lumens and illuminating your car with it. Don't delay, these things are GREAT!
    Can not be beaten by anything on ebay for the 31mm size. The LED boards you will see CAN beat the output but with these I see no need for a resistor to be placed in-line for fear of overheating and blowing led's.
  • Very good instrumentbulb.

    the picture i am posting from these bulbs installed in my maininstrument of my 2000modell Volvo C70 are going to speak for it self. very nice light, and reliable.
    might be tricky to get into the hole for bulbs as the LED bulbs on each bulb sticks out a little.
    VERY nice buy! greate price, supernice lighteffect.wouldn't thought White LED would give out perfectly dimmed "blue-ich" light from my standard Main instrument on my 2000modell Volvo C70.se pictures i have added! :)
