AC vs DC
 
Hi Folks.
I have a question more regarding an LED product as opposed to a computer question but figured if people who would know the answer sit on this board.

Ok so a few weeks back I bought an LED tape (a 16' long strip of LED's) that is set up for 12 dc power. I used it in my work truck to illuminate the cab and cap/tool boxes. This got me thinking. Why can't I use something like this with a transformer in a residential application as an accent light. I know my idea will work and I have a transformer but it's 12v AC. Will alternating current work on an LED set up for DC?

Thanks!

Simple answer is NO.

I by no means want to sound like a jerk but could you explain why? Now that I'm thinking about it, I have used LEDs on my boiler system to show me the zone valves were activate and that's 24v AC. Bought the components from radio shack.

Thanks

The main thing is the difference between ac and dc, and not all leds are for 12v dc. There is different leds for different applications.

Actually, I think it would work. But the LEDs would be turning on and off 60 x per second. But you could just as easily buy a 12 VDC adapter that gives you filtered 12 volts DC. If you plan on putting this in your house, even better would be to post the question in the Electrical forum so you can be sure you are doing all this safely. Besides just doing it safely, I would be converned of ensuring that you do not burn out the LED's.
