   The world's best 12V. light bulb?

   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)
