Hard to say - I would swap in a known good bulb from elsewhere in the string and see if it has the same problem.


If so, then could be bad wiring at or to that bulb (which would be dangerous because the dimness would be because the wiring flaw is pulling a lot of the juice that the bulb should be getting, which would cause heating at the flaw.


Other likely cause - and probably most likely, is if the string (sounds like a track light or series of recessed ceiling lights), it may have individual transformers at each fixture instead of one serving them all. if the transformer is going bad, could cause dim (or overly bright) bulb. Would require a new transformer (or in many cases intire head unit) if that is the case.


Either way, a volt-ohm meter check on voltage at the fixture would answer it - clearly not for you to do since you asked a question about it, but an electrician or electrical-handy handyman could check it out.


Or, depending on what a new head costs (if user-replaceable type rather than built-in), might well be cheaper to just replace the head if it is not a problem with the bulb itself. This assumes it is the type with a transformer on each head.


Footnote - I have been hearing, and reading recall notices, on a LOT of this type of low-voltage fixture. A LOT of the junk coming from Asia is just plain dangerous and grossly under-designed orpoorly made - personally I recommend against using any type of low-voltage lighting system except for outdoor landscape lighting where the low voltage is a significant safety consideration - way too many of them are just a fire hazard waiting to break out.
