We have a 12 volt PV system in our house that operates our yard lights
plus a few lamps and outlets inside. We have been using 12-watt (40
watt incandescent equiv) CFL's, with pretty good results. I recently
splurged on a 12-volt LED lamp just as a test.
There is one lamp that hangs between our easy chairs that we use for
reading every evening. We have always ran two of those 12-watt CFL's
with a Wye adapter. So when our new LED lamp arrived, I replaced one of
those CFL's, planning to run a long-term side-by-side test.
You could feel the difference in efficiency by simply feeling the lamps!
The CFL was distinctly warm while the LED was only slightly above
ambient temperature. The comparison test was quickly abandoned because
the combination of the LED and the CFL was too bright! So now we have
one LED bulb that is producing definitely more light than the two CFL's
together. (Yes, our CFL's may have been a bit tired)
This is the light bulb we bought:E27-NW12W-G-12V We selected the
Natural White color temperature, but it's a bit on the harsh side. Next
time we will try the warm white.

Does anyone else have any similar recommendations? Anything out there
cheaper?
(We have no connection to that particular company save having made that
one order from them)
