I'm new to this and haven't built a project yet, but I'm thinking about building one with a 575 watt metal halide bulb... that sounds like it would cost a lot of electricity. What are the real electrical costs of a setup like this? How does the power consumption compare with a regular CRT tv set?
no you dont...
compared to a crt set, the projector will use a tiny bit more power. not a WHOLE lot. but about as much as a rear projection set. not a real big concern. when i had mine, and had my whole stereo running, ALL day, my electrical bill went up like $5 or so a month. its pretty small. it definately not a factor to consider if you are planning on building it... the cost of $5 is so much less than the cost of building the unit...

I was going to say the same sort of thing....
If you need to worry about the cost of running a lightbulb...the cost of building a projector will seem ASTRONOMICAL and cost prohibitive.

The fact that you have to turn off your lights and darken the room is going to save a lot of that electricity- probably enough to make this more efficient than a CRT.
Also, the blackout curtains will give your windows extra insulation in the winter, and will block out heat in the summer.
In addition, in the winter, if you are using non-heatpump electric heat, your projector (and a regular TV) will produce about the same amount of heat per watt as your heater- so any extra electricity used by your setup will prevent your heater from burning that same amount.
