How can I optimise the lifetime of a Nikon speedlight?

Question

I have an SB-800. It's the newest Nikon strobe that will work with my F5. My F5 will probably outlast me (it probably has another 100,000 shutter actuations in it and I use less than 10 rolls a year, but I likely won't live another 278 years...).

What is my optimal strategy for making sure the SB-800 lives as long as possible?

Certainly storage advice suggests that if you don't use your speedlight much, you should take it out of storage every month or three, put batteries in and fire it a couple of times. But, my interpretation of this advice is that not to use the flash at all will shorten its life. I understand that. But what if I can choose to use the flash regularly, or not? Let's say I have two SB-800 stobes, A and B, and I store A in this way, taking it out and firing it monthly. Strobe B, on the other hand, I use every day or two (and carry with me).

Barring accidental damage, which strobe is likely to last longest, A or B? Why?

My question is essentially motivated by the fact that I could keep using my SB-800, or buy an SB-910 and mostly use that (effectively reserving the SB-800 for use with the F5).

Answer 1

Depends if you need CLS or not. (Don't even know if the F5 has CLS).

I'd keep the SB-800, and use it until it dies. The Strobist folks snap up all the good used Nikon strobes, but they are still tons cheaper than the SB-910 (and the Canon equivalent).

I consider strobes to be like tires on my car. Good to have good ones, but they are normal wear items, don't expect it to last decades.

That said, I have a 1970s vintage Vivitar 285 that still works, and it works fine on my Nikon F. But its voltage is too high for modern digital cameras.
