I have seen them on ebay I get mine local in portland oregon for under $6.00. I go through one every 50 hrs or so.

I buy at least 6 at a time so I dont have to worry.

It is a great flashlight.

I saw one of the new lithium that stream light came out with and it is very good but I will wait untill they have on that is just a little bit more powerful.

I have had a switch go out and had the lens replaced once due to scratches.
