In your lighting tips somewhere, you suggest using T8 in order to avoid the old problems with less-updated flouescent light sources such as hum, flicker, etc. But what about the T4 & T5? Do they also eliminate the fum & flicker?

T4 and T5 fixtures also do not hum and flicker. I use T4s in my house as over cabinet lighting and pantry lighting and they are fantastic! Highly recommend!
