Hello!
I have two Silma 250S projectors, one with a 12V 100W halogen lamp and the other with 12V 100W FCR lamp (with built-in mirror). I don't see any remarcable differences in picture image, but is there an advantage of one of the two types, or other diffences one should know of (lifetime,...)?
Thanks!!

The EFP (A1/231) with its own reflector has the advantage that when you replace the lamp you also get a new reflector.
With the FCR (A1/215) when you replace the lamp you will still be using the projector's own reflector once again. But, if you are lucky, the reflector should, in fact, last a long time. But there's always an if!

Thank you, Maurice!
Is it possible to clean the mirror in the projector or better not touch it? Thanks! [Wink]

The mirror being in the same draught from the fan as the lamp should not really need cleaning. It must never be touched with bare hands/fingers.
The careful use of a blower brush might be acceptable, but really should not be necessary.
The silvering of a mirror doesn't always last and may eventually begin to crack. If this happens, do not touch it anyway as it will make it worse.
