Where I go to school the progectors there are on for about 8 hours every day and none have had any bulbs replaced. In fact, progectors don't have bulbs to my knowledge, probably ultra-bright LEDs or somthing/
Nope - bright TV projectors still use halogen or similar bulbs - and they aren't cheap. The brighter the projector - the more esoteric and expensive the bulbs are. Whilst LEDs are being used for direct view screens (where their light is concentrated over a small area of less than 1cm2 - I don't think they are used as projection sources where their light is spread across screens more than 1m2)

Just had a thought. If those new screens are projected, won't they cost a lot to run / not be that practical?
Projectors always seem to require new bulbs on a regular basis and I always assumed they shouldn't be used for long periods of time.

Don't forget that the best way to shorten a light bulb's lifetime is switching on and off (heating and cooling quite simply), as well as moving them when they're hot (OH such a bad idea!). So keeping them on for long periods might actually pay dividends lifetime wise.
