Yes, the Sunshine Systems GlowPanel 45's do work well. I still like them too, and they seem to grow plants as well as the LED Grow-Master LGM 540's that I also use, but which are much more expensive.
These LED lights are great for gently acclimating recently deflasked tissue-culture plants, and for growing during the winter when other plants are in dormancy, getting an early start on the next season with seedlings or tissue-culture babies.
