Hi all. I'm trying to build a home brew LED lighting system for a converted bus (ie, school bus to motorhome conversion. FYI, they're a very cool way to roll. ) and one of the questions I have is this. The power system aboard is all 12v, both for the starter battery, and the onboard solar charged 12v "house" power. (they're identical to allow me to switch back and forth between the two if needed) Anyhow, the lights I want to hack into the power system are 6v 1.5w LED "pucks". I know that if I apply 12v, all I'll end up with is blown lights, and quite possibly a house fire. However, I also know that you can wire in line a few diodes and get a proper voltage reduction. The problem is, I'm not familiar enough with diode ratings to know for certain how many olms of diode I need to reduce it from 12 to exactly 6v. I've looked at the diode calculators on the web, but what they tell me makes about as much sense as brick dust in a birthday cake. I do think from a mechanical mindset, and have lots of hands on experience with electricity, but when it comes to things like this, I'm lost. Can you guys help me figure this out? I'd really appreciate it. Thanks.
