any experience on life of CF lighting
 

Today I installed an ahsupply 1 x 55 kit. Cool beans. Other than my own
stupidity of trying to install the ballast the first time in a location
where it couldn't possibly fit, all went well. So, how frequently do these
bulbs get changed? Surely not once every 6 months.. I hope.

It depends on the bulb. I kept my 96-W Panasonic bulb for almost 2 years
before replacing it. But the replacement bulb, which was a cheap generic,
only lasted 4 months before the glass cracked. On top of that, the generic
was not very bright to begin with and it lost more light intensity during
the 4 months than the Panasonic during the 2 years. So stick with brand name
bulbs. I believe AH Supplies carries them. They should last at least one
year, but then again, it depends on how much light you're willing to lose.

CF bulbs lose some intensity during the first month of use and then
they don't lose much at all. I know people who've been using the same
CF bulbs for 3+ years w/ no problems.

While I've been one of the strongest proponents of changing bulbs
every 6 months it's been pointed out to me that if you have a graph
of the decay in luminous flux over time and find that, say, a bulb
goes to 50% in one year but doesn't decay much afetr that, then
the thing to do is use twice the number of bulbs and leave them
till they go black.
