Yes my tank is lite-up by Giesemann bulbs.
About 9 months ago I talked to @Chris@CoralVue about the new Giesemann bulbs and we went over the color graphics for a bit, after 20 min I was convinced so Chris did send me all colors available for my 8 bulb unit.
Since two weeks I've changed the 4 bulbs I run the longest even my par was still good.
I must say I'm more than a happy camper with these bulbs.
