Today I decided it was time to change my bulb in my LG CF-181D 120hz HDTV Projector I purchased a few years ago. The projector was starting to get dim and movies were getting hard to watch with all the lights on in the room even with my Screen Innovations Black Diamond 1.4 gain screen. After replacing the bulb with the free spare I received when I purchased the projector the results were dramatic. The brightness feels like twice as much as it was before which was more then I was expecting and on top of that the colors are much more vibrant (wasn’t expecting this).
Update
———–
I just realized that the bulb is supposed to last 3000 hours according to LG so I replaced it ~400 hours before it was supposed to die, that being said the brightness lost was pretty bad so even though LG and I’m sure other projector companies tell you a bulb will last for a period of time expect it only to be at optimal brightness for 2/3rd’s of that time since I noticed the brightness going down over the last few months.
One of the most surprising new 1080p models coming to market this year is the LG CF181D. At an official street price of $2,499, it is the least expensive LCoS 1080p projector to come to market in 2009. It is also, hands down, the brightest home theater projector we’ve ever seen when calibrated for optimal video performance. It is scheduled to commence shipments toward the end of the month, but we’ve had a chance to see a late edition pre-production unit. LG has come out of the blue to challenge Epson, Mitsubishi, and Sony with a formidable offering of their own in the mid-$2,000 price range.
Overview
Brightness. This may be hard to believe, but after calibration, we measured the modified Cinema mode on the CF181D at a whopping 1219 ANSI lumens, with lamp on high and lens at wide angle. We normally think of 800 lumens as being the bright end of Cinema modes in home theater projectors, so this is an astounding number.
For dark theater viewing at screen sizes of 120″ to 150″ diagonal, 1200 lumens is way too bright. In order to cut brightness, you can go to low lamp mode, which dropped our Cinema mode to 887 lumens. For most users, that is still too bright. Lumen output can be cut further by setting the projector farther back from the screen and using the long throw end of the zoom. If you set its 1.8x zoom lens all the way back to its maximum long throw position, brightness is curtailed by another 26%, down to 656 lumens. That’s not much loss for a zoom lens of this range-normally we’d expect to lose about 35% on a 1.8x zoom lens.
