Due to the bright bulb, the 3M 2000 overhead projector can use a substantial amount of power and is not, unfortunately, Energy Star rated.
A good projector will have 2000 or more lumens, but an LED projector will have much less.
about £100 to £2000
It depends. Some don't cost that much it all really depends on ehat kind of features that are wanted in a overhead projector. They can be hard to find though.
The Cost of a projector depends on the type, brand, store and type of projector bought. The price can range from $50-$300+.
The 2000 model did not have a 350 in it.

There are many websites that provide DIY projector plans, But none offer a way to repair a Projector Lens. I would look into how much it is to replace the Lens or the projector all together.
No projector requires a screen, but all will look much better than being projected on a wall.

The power rating is printed on the lamp holder, expressed in watts. As power describes the rate of energy consumption, you need to convert the number of watts into kilowatts (divide by 1000) and multiply this figure by the time for which the lamp is in use (expressed in hours) -this will tell you the number of kilowatt hours of energy used.
