Interesting...I would rather have something lay flat than mounted though, is it ok for the fixture? If not Im fine with mounted.
I'm also unfamiliar with external ballast systems, do they take up much room? This is going to be on a dresser.
If you havent noticed Im all about space...
One thing though, theres only one switch for the 2 bulb fixtures so is it still safe to run without a bulb?
