Is anyone here familiar with overdriving NO fluorescent tubes?

I met a DIYer today that does this to his lamps.

Apparently you replace the balast with a higher output Electronic
ballast
(About $10 from home depot) and it can double even triple the output of
the
bulb. It operates at a higher frequency and does not shorten the life
of
the bulb much at all. He's had a setup with a twin 30w 36" fixture that
with this balast is doing130watts after 1 year.

Anyone have experience with this?

Just a little FYI... I tried doing this tonight, I had everything set up.
The stupid lamp holders take 18GA wire. I was so ticked! I went with
14GA
which was too big. =|

Oh well, I'll try again tomorrow if I get time...
