I have taken my own measurements for Brightness and Power for each of the projectors. I will incorporate this data into the respective review pages, but wanted to talk about it here in more detail since it is the first time I’ve done this.
Methods
Setup
1. Remove battery from projector (if it has one)
2. Set to maximum brightness
3. Connect to computer and show a blank (100% white) PowerPoint slide
4. Minimize light (all lights off, window blacked out)
Power Measurement
Take a reading from my Kill-A-Watt. This is set for US 110 volts and I did the reading in watts.
Brightness
Take reading from around the screen. I used a light meter, set to Lux. The screen was 39.37 inches (1 meter), measured diagonally.
Here is the key:
T=Top
B=Bottom
L=Left
R=Right
C=Center
Q=Quarter

This data begs for a chart or graph of some kind, so here is one I did in Excel for the MPro120. To make it smooth, I had to generate the data myself for any blank cells. I did this by simple taking the average of the two adjoining cells.
