Canon LV-8310

Noise (7.41)

The LV-8310 is a reasonably quiet projector: we measured the noise level at an average of 46 decibels in the standard mode, which is somewhat quieter than most others. This is, in part, due to the large size of the projector body. A larger size provides more area inside for the heat to be exchanged with the circulating air, so quieter fans can be used. If you don’t mind loosing some brightness, the Quiet Lamp mode cuts the noise level down even further to about 41 decibels.

Heat

In all of the image modes that the LV-8310 offers, we measured the temperature of the air exiting the projector body at a toasty 87 degrees Fahrenheit higher than the air going in. The air was no cooler with the projector in Quiet Lamp mode, but the noise of the fan was much lower, so it is presumably using a lower fan speed and a lower volume of air to cool the projector.

Power Consumption (6.99)

The LV-8310 sucks down quite a lot of power when working; we found that it used an average of about 307 watts when running in most modes, which would cost about $60 a year if you used the projector an average of 5 hours a day. This can be reduced somewhat by using the Quiet Lamp mode: this lower brightness mode uses about 235 watts, for a typical yearly running cost of about $45.90.

We found no significant difference between most of the modes on this projector: they all used about the same amount of energy.

Mode	Average Watts	Cost per Year
Standard	308	$60.14
Presentation	307	$60.08
Cinema	307	60.08
Presentation (Quiet Lamp)	235	45.89

Lamp Life

Canon claims that the LV-LP31 lamp that this projector uses has a lifespan of 4000 hours in normal mode, or 5000 in Quiet Lamp mode.
