Who's using a Magnetic MH Ballast?

I'm just curious, let me hear how you fell. How long have you used it for? any problems? how louds the hum? annoying? any or all comments?
If your using a electronic blaast now but had a magnetic in the past, why the change. Thanks

 

I had a cheap one I don't remember where from the thing hummed and got hot enough to cook a egg. electronic would be what I get if i ever get another one.

 

I've been using the icecap 250w electronic. Gonna go M80 magnetic to use the radium bulb when I setup my next aquarium. Other than that bulb I would stick with electronic.

 

I use both.

Hamilton Tech 2 x 250W Magnetic
PFO 1 x 250W Electronic (2 of these)

SPS 14K bulbs on all 4 fixtures

The magnetic does run warm, but I wouldn't say it is a lot warmer than the electronic.
It does hum, but not as loud as my powerheads. It is about 5 feet from tank, can't hear it over the skimmer.

The magnetic does take longer to get to full power, but the coloring is better IMO. It just seems to be a much "fuller" light. The blue is a tad bit bluer, but noticeable.

Personally, I will get another magnetic when the PFOs go out.

 

I compared both PAR and color of magnetic and IC electronic ballasts on my tank.

I actually get better light and more PAR with the electronic ballasts, plus they draw less electricity, are smaller and weigh less allowing me to mount them wherever I want.
