Electronic select-a-watt HQI setting same as M80?
Just wondering if what makes an M80 ballast an M80 ballast is the wattage outputted? Or is there more to it?
These new electronic ballasts by SLS and Lumatek have HQI dials but does that mean they drive an HQI bulb (like the 250W Radiums I want) to spec (M80) or am I better off with a real M80 ballast? |
