I tried the 400w radiums,helios and ushio 14k SE's on Galaxy's but still went back to reeflux 12k,the others were to dim but your colors look awesome-maybe it's the bluewave's??
I am not a big fan of eballasts, if you are going to do it, do it big
Besides, radiums are a true HQI bulb as well as aquaconnects. They will work on e-ballasts, but they will be bluer and dimmer. On a true HQI ballast, they are a crisp white with a tint of blue.
The darn thing with coralvue bulbs is their inconsistencies of darn chinese bulbs. The quality control department in non existent.
