Okay, now you're just screwing with me. =p+1 on the bucket, and put only the light head in the bucket (of water), batteries don't take to kindly to water.

Those black flecks aren't on the bulb, they're on the inside of the tube that encases the bulb, and they're not a problem. You can remove the tube (it simply pulls off over a couple of o-rings that hold it in place) and clean out the inside of the tube with a q-tip. Blow some air in there afterward to remove any flecks of cotton from the q-tip or you'll end up with more black flecks. Push the cover back on and replace the hood and you're good to go.Anything else I should look for to make sure it's in good shape? Are they any specific red flags? I had a look at the light last night and noticed little black flecks in the bulb (might have just been in the lamp cover). Is that normal? Also because the can cap is transparent I could see that a couple of the little screws in the cap have small amounts of rust at their tips. Is that anything to be concerned about?
Hmm, how does one arrange a burn test before a sale? According to the seller she used to get 3.5+ hrs on a charge, and that it's been lightly used. Any way to test this, short of hanging out at her house for a few hours while it's on?

I've owned one of these lights for almost 10 years now ... since Barry (the former owner or Salvo) first came out with the 21W version. Mine also has the clear cover. It's an amazingly durable light ... I have probably 2000 dives on mine. It just went back to Light Monkey for service because I flooded it on a dive trip ... but I tend to use my equipment hard. It's on its second battery and second bulb ... and probably its fourth cable. But it takes a licking and keeps on ticking.
Typical burn test consists of turning on the light and dropping the light head into a bucket of water, then timing how long it takes for the light to go out.

Points taken. The problem with not knowing what you don't know is that when you know you don't know what you don't know then you might assume that there's much more to know than there is.
