SF 9AN Bulb life?

[2hotford]

Hey guys,

How long on average do the bulbs in the SF 9AN last? In other words, if the light is used daily for 30 munutes or so, how many spare bulbs should a person have around?

Thanks
Tim

Now how many spares to keep? At least one..I like to have 2 so when I use one I have time to replace it. I have gotten 25+ hours and over 38 (just a little over) this was "hard duty" not just thirty minutes a day. Just my thoughts on this.

I read 30-50 hours somewhere for std SF bulbs

When Silverfox offered a B90 replacement pack I was given the chance to "test" a protopack. That involved repeated charging and running the pack in my 9AN many many times over weeks. I have not guessed at my numbers nor read them somewhere I really do have a 9AN and ran the tar out of it checking the protopack Tom sent me. I do recall reading (I think on the SF website) the standard P60/P61 were rated at 25 hours I am sure some of mine have more hours on them. I do not recall reading any thing as to the lifetime of the standard N90 lamp.
