Joe Luxo Fluorescent KFM Magnifier to LED Conversion posted 02/11/2019 I wanted to let you know that the Super Luxo (my name for the LED upgrade) is still going strong since your conversion in January 2018. It hasn't so much as flickered. Your LED kit has really taken the standard fluorescent Luxo to the next level. The dimmer function is especially nice. I usually leave it on about half way as that is plenty bright enough for use with my PC. The light stays on a average of 16-20 hours a day, as I kind of use it as a night light for that room also. Thanks.
