The lighting on Santosha was all G4 halogen bulbs between 10w and 20w. I ordered 2 batches of 10 LED replacements from a China supplier on ebay with an individual bulb cost of about $7 USD. The 6 SMD are 1.5w and fit in the small round overhead fixtures nicely. The 8 SMD are 1.8w. All are 2700k color temperature which is warm white. Care needs to be taken not to break the leads loose from their printed circuit boards, this happened to several that I was a little rough with but I was able to super glue them back in place with no problem. I used some dielectric grease on the leads to prevent corrosion.
I am very pleased with the new lights and the color they produce. They do not get hot and save about 35AH per day in normal use.
