how much power does 3D projector and 3D TV take?

[kevotinh]

I have a 55" LG 3D TV. I want to get a bigger screen. Not sure if I want a projector or a TV. I heard projector takes alot more power than tv. Anyone knows how much power does a projector takes and how much power does a TV takes in general?

What? Projectors do not suck up electricity. I don't know where you heard that from. I've owned quite a few projector setups along side larger LED/Plasma screens and I haven't noticed a spike in consumption (on my bills).

And why do you think that is? It's because "power consumption" has been so blown our of proportion when applied to consumer TVs and projectors. Why people would even consider something so minor when deciding what to buy is simply beyond comprehension, and makes me give a huge . In most cases, you are looking at far less than $100/year difference between the "best" and "worst" displays. With projectors it's a fraction of that.

Not directing my ire toward you, only expanding upon your comments.

I know that projectors do take more power to run it. But I am not sure of how much when come to pay your bill. A LED takes about 50w to 100w. But projector takes about 200w to 400w. It does take up twice power. But I just not sure how much of that translate into dollar bills. If you would have your projector runs about 10 hours a day. How much will your bill going to be for a projector.

And thanks for your answer, I will keep that in mind when deciding which one should i get.

10 hours a day?

Okay, we'll use that number. Assume $0.085 per KWh, which is what my electric rates are (approximately). Assume an Optoma HD20 @ ~300W. Doing the math, you'll consume 1,095 KWh, or $93.08 +tax per year.

I am curious of how did you do the math. with all the numbers i am confused. how did you get 1,095 kwh. when a projector is consume 300w. is that 300w per hour??

Projector consumption per hour: 300W
Daily usage: 10 hrs
Annual usage: 365*10=3650 hrs
Annual power consumption: 3650hrs * 300W/hr = 1,095,000W
1000W=1kW: 1,095,000W / 1000 = 1095kW
Assumed cost per kWh: $0.085
Total annual cost: 1095kW * $0.085/kWh = $93.075

thank you very much. Now i'll look more into projector for my next purchase.
