My old lighting store sold a brand that also worked very well. They were available in a multitude of light colors/temps. I will look online and/or contact them once they open and ask what the brand was.

I did not use them unless they were specified by the customer, because they were expensive.

"Dimmable" fluorescent lamps are relatively new technology, so there are going to be some growing pains for a while. There is a system the alternates the current On/Off at an incredibly high rate of speed. This allows for a "dimmer" effect, but these are mostly for large commercial areas.
