[AT] LED lights

I just replaced the 5 40 Watt lamps in the ceiling fan in my living room with
5 7 Watt led bulbs. That drops the consumption from 200 watts to 35 watts.
That alone will pay for the conversion in a pretty short time. The only down
side is that it takes about a minute for the led lamps to reach full brightness
and they were made in China. But then so were the lamps they replaced. :o(
Since you are looking at using them in a barn running on a 12V supply, there
will be some losses in the AC-DC conversion, but line losses shoule be minimal
if you use the appropriate gauge wire for the required current. I have a chart
I can scan and send you if needed.

The cost of 110-volt LED's is still pretty high and there doesn't seem to be 
much available on high-output, at least that I could find.

I know they use 12-volt lights on boats and vehicles but am wondering why I 
could not do the same in our barn.

There are quite a few 110v power supplies that output 12-volts DC.   saw one 
that might work on Amazon...

LED's draw about 3 watts each, so they really don't take a lot to power 
them.

Has anyone done this?  I am not sure how much line loss there is with DC

Thank you.
