Looking for bulb!!

I am trying to find a 4.5 Volt 2.2 watt krypton bulb. It is similar to the type of bulb that fits a Streamlight Topspot.I have the Streamlight 5.2 Volt 2.2 watt krypton bulb but need the I believe is 4.5. Its powered by 3aaa if this is wrong voltage I am needing please let me know. If some one could tell me the type of bulb it is such as T3 or what ever the base is I can google it. Any help would be greatly appreciated.

Thanks!

It would help if you could tell us which light you need it for. Make and model.

Kinda embarassed to say cause you guys have such fantastic lights, but it is a Winchester light aluminum with rear clickie with 3aaa carrier. I got it with a knife set and basically it is a good tool box light. The bulb looks sorta like this one http://www.lightbulbwarehouse.com/lightbulbs/mini.html T.175. I cant find pic of it anywhere on the web and I know its just a rebranded light thats probably not worth the price of a couple of bulbs.But I did put in a bulb for a Streamlight Top Spot and it made a great improvement. The Top Spot is a 5.2 volt 2.2. So I know i am not pushing enough volts. I have reoringed evreything including the lens. Made a pretty good light out of what it was.

Sorry if this was more than you needed to know. Thanks for your reply

Your light is a Winchester Tacti-light made be Gerber. I think it uses these bulbs.

Exactly the bulb! Thanks a million DUQ! Thats the bulb but my flashlight doesnt look anything like the Gerber Tacti light. Will have to post a pic of it if I get a chance. Mine is a straight cylinder aluminum. It maybe a strange bird. Will try to post pic. Thanks again!
