Awhile back, I posted a question about making fluorescent undercabinet lights touch-activated, but got no response. However, I did stumble across the Touch-n-Glow touch activation adapter for fluorescent fixtures, that promised to do just what I wanted.
Well, I tried it, and after a few days, it stopped working and is stuck on the "on" setting. Up until now, it also occasionally would turn off by itself.
At least for now, I couldn't recommend the product.
