The projector's temperature will be higher. And the fan will work harder than beginning. It will make a louder noise. So we give the noise and temperature result after 2 hours continuous working.

The Truth about Lumen. Why Lux and not lumen? First of all we have to define Lux and Lumen. Lumen is the value that states the total optical power of a bulb or LED, in other words the light that is emitted in ALL directions. That means, if a LED has 1000 lumen then this LED is beaming the 1000 lumen in ALL directions, therefore 360° degrees. 950 lumens is slightly less bright than the output of a 100 watt incandescent bulb. (100 watts = 1160 lumens, 60 watts = 630 lumens)

Lumen and Lux. The lumen is a significant entity: it measures the total amount of visible light emitted by a given source. Transition from watts to lumens. It does make any sense to evaluate the amount of light according to the watt consumption of the lamp.

The lux (symbol: lx) is the SI derived unit of illuminance, measuring luminous flux per unit area. It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface.What projector should I use with MotionMagix.

Since lumens are the measure of light over a certain area, the lux of specific spots on a projector screen must be measured and then averaged out over the screen's area. A common photographer's light meter is sufficient for measuring the brightness of a projector with a fair degree of accuracy.

I think a helpful way to understand this is to look at measured lux divided by lumens to look at how efficient the light source is at projecting light for the given level of output. (Note I think the HIDs are cheating a bit in these measurements, as a 3200 lumen HID should be 35w, 40+ watts as measured will increase output beyond 3200 lumens ...
