Gotta agree here. I was lured by the $7.00 price and bought three.
They were completely burned out after 2 years.

Gotta agree, again. My tritons burned out after less than a year
(yeah I know I'm supposed to replace after 6 months) and the Vita
Lites didn't last much longer. The LOA ballasts start the bulbs
instantly, blasting them with an electric charge that's accompanied
by groaning from the entire fixture.

My LunaPro light meter matches neither of my Nikons. It's almost
a full F stop off. The Nikons agree within 1/2 F stop of each other,
but the whole thing is confusing. I'm using 8 bulbs just to be
sure I've got enough light!
