Query: Very short life

Like most of my experience so far with florescent lamp bulbs, the life span is too short to make up the extra cost compared to an incandescent bulb. This one lasted a few months, but but more importantly, I received a small fraction of its' advertised hours of life (6000) -- I got about 400 before it died. I read somewhere that you get better life out of fluorescent lamp bulbs if they are not cycled frequently, and let run longer (e.g. not good for a quick bathroom break), but this particular lamp was cycle maybe 2 times per day, and usually left on for 1 hour minumum.I'll continue to buy these types of bulbs, mainly for the reduced heat, but I won't be buying this one again.
