We have a lot of track lighting that was using MR 16 metal halide 12 v mostly 20w and some 50w. I had replaced them about a year ago with some Chinese LED 3 w super white. The lighting is amazing and about the same lumins as the 20 w they replaced. Of the 20 pcs I had purchased 2 had quit. Oh well I suspected they may not last. I still intend to buy a bunch more for some other fixtures. I like the super white lighting. Most of our lighting in the house is the 12v MR-16 powered by some large format batteries that are waiting for solar PV install. For now they are charged via a high end charger powered by the grid. Running the calculations it will take 20 years for the lights ROI. But that is at todays dollar. The next time we have an increase in the cost of energy that ROI time will shorten. Just hope they will stand the test of time.
