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.
