is anyone familiar with the LED boards for cars like this one : This product is no longer available. ?
I bought one of these from ebay for a few bucks hoping to use it over a small aquarium. This this is total overkill for my purpose, it is super bright. Its hard to compare it to flashlights with reflectors but i bet this thing is putting out 500 lumens. My question is I was going to salvage an old 12v adapter to run the bulb but how do I know how many amps the adapter should supply? Will the bulb only draw what it needs or does the adapter need to supply the correct amperage? I have no idea what the correct amperage would be but supposedly these bulbs only draw 3 watts. Thanks for any advice.
BTW the one I bought has 24 5630 LEDs.
