![]() I bought a real one
![]() ![]() I know this doesn't answer your question, just thought I'd share that my plan all along was to use a M80 ballast or HQI if you will, with the Radium. If you don't get the answers your looking for, send a PM to Paul Erik (lighting Guru) Reef Central. |

![]() Share what you find out on here. I was curious about this too when I saw the lumatek for sale at Progressive Reef.

![]() I highly doubt that the Select-a-Watt ballasts are true M80s.
Firstly, they're marketed as "electronic". An M80 is a magnetic ballast. Secondly, have you ever picked up an M80? It weighs a freakin' ton because of the huge transformer. The listed shipping weight of a Select-a-Watt is 6 lbs - much lighter. That said, I haven't seen any performance numbers, but I strongly suspect that it will behave like any other electronic ballast meaning that you'll draw a true amount of wattage and it will underdrive HQI-spec'd bulbs like the Radium (i.e. lower PAR). Radiums on electronics also tend to appear far more blue than they do while driven by a true M80. |
