Not really. IF you overdrive by 4..you get about 2-2.5X the wattage...and about
half the life..IE 2 years instead of 4...but if your changing them every six
months like the plant people reccomend..that really doesnt make a
difference....

Wow, that IS impressive! Is is safe to assume all the rating changes are
proportional? In other words, if you overdrive a bulb by two you doulble
the wattage and decrease it's life by 50%? Thanks for the suggestion.

Have you researched overdriving Normal Output Fluorescent lamps? Pretty
easy, affordable, and effective.
I just finished a project myself. There are some before and after photos
in
alt.binaries.aquaria if you're curious to see the difference.
