Hi Martin,
I think looking at the specs that the Philips should work. The Philips is slightly warmer in colour temperature and was probably designed for use in dental equipment and yes I suspect the light output will be lower especially given the 500hrs compared to the 50hrs of the Osram lamp.

There is also the 500 hours version 64620 of the osram bulb, which is rated for 500 hours?
First of all Thanks Maurice for welcoming me back to the forum. It's been a long time.
Back to the lamps. Yes reduced light output will probably have a positive impact on longevity of films but I think it will be extremely negligible unless you're thinking of showing the same film hundreds of time. To be quite honest I would get as much light through your films onto the screen and enjoy the experience. With low light on the screen you will not show the vibrancy of colour or the contrast of b/w film.
