rogerpete posted:Chris, I just ebay search "5m led roll", and a giant selection comes up. That's what I use on all my buildings and cars, the warm white LEDs.
I've purchased buck converters off the bay before, but was wondering if GRJ had a better unit that he was using.
The GRJ convertors are current regulators. They are a great product.
LED intensity is best adjusted with a current regulator. A nice smooth range of adjustment and very stable. With some of these buck convertors which are voltage adjustable, the proper voltage is very touchy and can change easily over time giving a very different intensity other than what was desired.
