I have been looking into the dimmable
mh lights tonight. so far all i have found that is promising is this link
Sfiligoi s.r.l. - aquarium technologies. They claim they have a controller (ACLS) that can dim
HQI MH fro 0-100%. I have read that the 400W icecap
mh ballast is dimmable to 50% but haven't found any other info. In the podcast the Coravue and Blueline
HD were mentioned but i haven't found any info on them. Please post if anyone has anymore info on dimmable
mh. thanks
