After watching a couple of movies tonight, I thought I'd meaure the actual lumens the projector was pushing out. Manufacturers figures are often inflated, and sometimes by as much as 40%, so I thought I'd see what mine was doing with over 60hrs on the lamp - this pj is rated at 900 lumens in high lamp, and around 700 in eco mode. Here are my readings (my meter reads lux): 199 lux in high lamp mode = 510 lumens 152 lux in low lamp mode = 389.3 lumens. So it seems the 40% rule isn't far out, and don't forget to factor the lamp dimming over time, so these numbers will reduce. While I'm at it, I'll mention the contrast ratio - this is advertised as 3500:1, where as I measured it at 2300:1 out of the box, and managed to tweak 2600:1 by using colour correction filters to achieve D65 calibration. Adding the filters also dims the image, but I'm still getting over 13ft lamberts from my 1.2 gain screen which is how I like it. As the lamp dims over time, I can swap two filters for a single multi-coated equivalent and gain some light back and keep the ft lamberts up. Gary.
