Rich, I replaced all the recessed light fixtures on MYSTY with LED's that I made, using the cleaned-up carcasses of the original fluorescents, some very bright double-wide LED strips, and buck voltage converters. I used buck converters (that's really what they're called) that I found on eBay. They serve the same function as the devices your link describes. I bought 5 at a time, and paid approximately US$10 for all, including shipping from China. I then, using an adjustable DC power supply, connected the completed converted lights and set the converters. I set the converter output to 12 volts when the input voltage is 15.0. The net result is slightly less light output at voltages lower than 15.0, but the LEDs are protected should the voltage go that high. Only one issue to be aware of. The converters DO NOT tolerate being connected with "+" and "-" inputs reversed. Don't ask how I know.... Bill MYSTY Landfall 39 In a message dated 6/28/2013 7:31:03 A.M.
