Well i guess I'll start by saying that this is my first able, so be gentle (; lol. I always seemed to have a problem with my halogen security lights burning out. I wanted a simple, cheap, permanent solution. Led's seemed to be the way to go. Im fairly new to 120V electronics and am learning quickly, but I've been customizing 12V for years.
Step 1: The problem
The first picture shows what has been happening to my halogens. Not just one or two but all seven. Not once or twice a year, but every few weeks. At about $6usd it can become an unnecessary headache. The second picture shows my personal choice for a solution. A 10w led:) The original halogen could produce over 3000 lumens, and this led produces around 950 so it's not quite equivalent. Having said that I chose the 10w led for several reasons. Mainly cost, and no heatsink fan needed at 10w. any higher and you would probably need a fan, which i couldn't get to fit tidily into the housing. 10w produces more than enough power for my application anyhow. The pictures are vague for lower light output, but i can see clearly in front of these lights for over 20 yards, or read a book easily at about 20 feet.
