True, it is old but the amazing thing is there is not a whole bunch of discussions around it online. Sanjay Joshi seems to be the only one that has done any extensive research, he has published some really good articles. If you check other forums, there is mention of it but they don't go anywhere. I guess it's not as cool as the new LED trend, but overdriving MH bulbs with magnetic ballasts is interesting nonetheless.
