I wanted a 12 volt lightbulb For my home RE system that looked and functioned like a normal light, brightness etc. But one that didnt use a lot of power. I found these at LOWES for under $10 and decided it was time to hack:)
Well here it is, bunches of LED's. First thing you probably want to do is measure where the power is being delivered to the board. In my case it was 30VDC. BE CAREFUL not to look at the lights when lit. Also take a voltage reading across ONE LED while its powered on.
