I've got a Mitsubishi WS-55909 and noticed that maybe other model Mitsubishi light bulbs would fit mine. And if anyone knows, can someone refer a link or a model of the bulb please?

Your set does not use "bulbs." It uses CRTs, red, green, and blue. Are the CRTs what you are referring to? What is your problem and why are you asking the question?

How long do these last exactly?

 

[lcaillo]

I would expect over 10 years with average use. CRTs begin aging when put into service and gradually get weaker over time. They will likely need alignment at some point to balance the output but can last many years with reasonable use. Again, what is the reason for the question?

 

[nouseforaname]

Just curious. I'm sure the convergence has nothing to do with the crt's then but once in a while I'd have to realign some of the points for a clear view.

Convergence has little to do with the aging of the CRTs, but everything drifts with age.
