| What is the Brightest 1080P Projector for Home Theater?
I'm still using my Studio Experience 20HD (Sanyo PLV-70) in my home theater, which has a fair amount of ambient light I cannot control. It's been a workhorse for me, and though it still doesn't do a great job on a sunny afternoon, I can still watch sports on it. Unfortunately, I have floor to ceiling windows, so the light is not very controllable - there are blinds, but they have a high WAF, and a low blackout capability.
For some time I have wanted to upgrade to 1080P - have been waiting for a PJ with at least 2000 lumens - and preferably 2500 or more. I'm told the AE4000 is fairly bright, and the new Epson's as well - perhaps they are actually brighter than the plv-70 after the lamp dims a bit from use - not sure.
At night, the room is plenty dark, of course, though the wife likes to have a fire going while watching movies (to my perpetual frustration as the light from the fire washes out some of the screen, unless I place an armchair strategically to block it, lol.)
Love to know what the latest and greatest is out there - ideally, something under 10K.
Thanks for any thoughts and advice!

| Probably the Optoma HD8600 my light meter got 37.50ftc which is 900 lumens on a 106" diag screen and that's tuned to D65k.
As a comparison the H79 was considered very bright, that one got 17ftc tuned to D65k. So 17ftcandles vs 37.5 ftc huge difference. The HD8600 could go to it's 1600lumen spec if you use the bright video choice. Which isn't D65k and uses a large amount of brilliant color to get that bright.

A big question depends on if you plan to have it calibrated properly, or watch it uncalibrated. Also your budget makes a difference. In my testing of pretty much everything out there, the RS15 from JVC is the brightest in the under $10k range. At max output calibrated, it hovers around 1000 lumens. Note as well if you "uncalibrate" it, I have tested it at about 1580 lumens, so again, one of if not the brightest.

I always thought the JVC's didn't have much left in the tank beyond D65.
How bad is the color if you do that?

Yeah not sure who started that rumor but it isn't true. Colors are really no worse than the competition that does the same thing...

| You might wanna check out "Deja Vu"s posts regarding color filters. He managed to get tons of lumens with a decent image out of the new Epson by using a couple of filters to tame the colors in dynamic mode.

But that may not be saying much, as most pj's are way to blue/green in "living room" mode.
Also puzzled because all of the reviews I've read say that the JVC's brightest modes aren't that much brighter than when calibrated.
Is this something new for the current generation?

| If I had to take a wild guess. The factory calibrated modes for the JVC are all relatively close to D65, much more so than most of it's kin. Reviews generally use the preset modes and maybe one custom D65 calibration. Sounds like Jason took an RS15 and intentionally threw it out of whack (farther than any of the presets) to see how bright it could go....

Not quite. There is a "High Brightness" mode in the new series, which is what I measured. The RS1/2 didn't change much, but the newer ones do.
And to Noah...the Epson's are heavy blue/green as well at their rated 1600 lumens...thus "uncalibrated".

Yes, that is interesting, and news to me.
So how usable is the color in High Brightness?
Is that its actual name? I just checked Art's review of the RS25 at Projectorreviews and he just mentions a Dynamic mode.
I'm not too picky; I'm still watching a stock RS1 am happy with the color except for sporadic attacks by the Green Demon.
If the answer is "Not very good", have you tried seeing how much of the brightness you could retain w/passable color?

| What about the LG CF181D- seems it can get pretty bright?
I bought the W6000 for similar reasons to yours- big screen and uncontrollable ambient light in a light colored room. About the worst possible scenario for front projection. I watch only HDTV/sports in the daytime/bright ambient light situations though, so accuracy isn't crucial. Standard mode, BC on, Normal color is around 7500K but 1250 lumens. Accurate modes (BC off, cinema, etc...) still crank out near 900 lumens, and is plenty for my large screen at night lights out.
I was waiting for the InFocus SP-8602, but I'd still be waiting of course and glad I went with the BenQ for the time being. I hope the 8602 can throw out some light and would provide a nice upgrade to the BenQ.
Here's a pic of my W6K/High Power combo, all white walls (tall ceiling makes painting a pain), two big windows, room open to the rest of the house, etc... obviously this shot is at night, but with the light on. The screen is 11.5ft wide 16x9 (159" diag).
Hope this helps.

It's not one of the memory settings...it is under the color temp settings. As with any other projector that is skewed...it is what it is. For sports and less "important" viewing, it would work fine. If you are watching a critical Bluray, not so much.

| Casio XJ-A255 WXGA Real (1,280x800) 3000 ANSI lumens
Casio's breakthrough with a 20,000 hour life LED-Laser-Florescent driven DLP projector will obsolete everything on the market if they can make it home theater worthy. The stated contrast ratio of 1,800 to 1 is low, but even a slight improvement and full 1080 resolution would make it a winner in the HT market. I emailed them and asked about the price. The fact that it is so darn small makes me think it may be affordable.

CASIO RELEASES WORLD’S FIRST* MERCURY-FREE HIGH-BRIGHTNESS PROJECTORS
New SuperSlim Projectors Feature Newly Developed Laser & LED Hybrid Light Source
LAS VEGAS, NV, January 6, 2010 — Casio America, Inc., and its parent company, Casio Computer Co., Ltd., today announced that it has created a mercury-free laser & LED hybrid light source, capable of high-brightness projection for use in the next-generation projectors the company has developed under its “clean & green” concept. Casio is releasing a line of GREEN SLIM projectors with the new light source, introducing the world’s first* mercury-free high-brightness data projectors.
Currently, high-pressure mercury lamps are used as the light source for data projectors capable of producing 2,000 or more lumens. Semiconductor light sources that do not contain environmentally harmful mercury such as Laser and LED offer promising light sources for next-generation DLP® projectors. Until now, however, they were only usable as light sources for small, low-lumen projectors because high-output sources capable of producing green light have not been possible for mass production.
Casio has changed all this by creating an original mercury-free hybrid light source capable of generating high brightness by combining a laser, a fluorescent element and an LED. Casio has achieved high output of green light, which has been considered difficult with conventional semiconductor light sources, by very efficiently converting blue laser light into green light, using the fluorescent element. The high-brightness light of 2,000 or more lumens was then attained by projecting blue laser light, green light converted from blue laser light with the element, and light emitted by a red LED through a DLP® chip onto the screen.
Use of the laser & LED hybrid light source makes Casio’s GREEN SLIM projectors the world’s first data projectors bright enough (2,000-3,000 lumens) for projection in a well lit room without using a high-pressure mercury lamp. Usability features have also been greatly improved: the body, no bigger than the size of a standard 8 1/2 x 11 piece of paper, is slim (1.7 inches) and lightweight (5 lbs). Additional qualities include: the projector produces bright colors through upgraded color purity, the light source has a life of approximately 20,000 hours, projection at maximum brightness is possible in a minimum of eight seconds and no cool down is needed when turning the projectors off.
* As of January 7, 2010, for high-brightness data projectors with at least 2,000 lumens. According to a Casio survey.
“Casio is thrilled to introduce this entirely new lineup of eco-friendly Super Slim projectors,” said Toshiharu Okimuro, Chairman of Casio America, Inc. “The advances we have made to provide superior brightness and energy-saving features make it the perfect tool for the road warrior, instructor, gamer and general consumer for home entertainment.”
GREEN SLIM Projectors will be available in a diverse lineup, including a model that can accommodate WXGA Real display at 1280 x 800 dots (16:10) and a model that can project without a PC and can communicate wirelessly with PCs. These projectors will greatly broaden the possibilities for visual communication thanks to Casio’s advanced laser & LED hybrid light source, which will fundamentally change the status quo in projectors and provide enhanced features that make the projectors usable in diverse situations.

Main Features of Casio’s GREEN SLIM Projectors
Laser & LED hybrid light source that enables mercury-free, high-brightness projection
High-brightness projection is achieved without using a high-pressure mercury lamp by using blue light emitted by a blue laser, green light converted from blue laser light with a fluorescent element, and light emitted by a high-lumen red LED through a DLP® chip onto the screen.
Standard paper-size, high-brightness projectors
High-brightness projection is achieved at a maximum of 3,000 ANSI lumens (XJ-A255/A250/A155/A150) with a laser & LED hybrid light source in a slim (43 mm) and lightweight (2.3 kg) standard paper-size body. These projectors can be carried together with documents without being bulky and can project clear images even in brightly lit rooms.
Superior color reproducibility increases presentation impact
The laser & LED hybrid light source greatly improves color purity compared to high-pressure mercury lamps. It enables the production of beautifully vivid colors and projects clear, powerful images with visual effects of high color purity.
Longer light source life
Use of the laser & LED hybrid light source increases the light source life to approximately 20,000 hours—nearly 10 times that of Casio’s conventional products (XJ-S58, etc.) with a high-pressure mercury lamp—which means less maintenance and lower operating costs. Moreover, brightness deteriorates more slowly than with mercury lamps, so clear image quality can be maintained for a long time.
Quick powering on and off, an advantage for smooth presentations
Projection at maximum brightness is possible in a minimum of eight seconds, and no cool down is needed when turning the projectors off. Thus, limited presentation time can be utilized effectively by enabling a smooth presentation flow from set-up to clean-up.
Wide-angle 2X optical zoom gives users freedom of projector setup
These models come with a wide-angle 2X zoom lens (lens with a two times shorter focal distance) that provides the greatest magnification* of any data projector. They are also equipped with a feature that automatically corrects vertical distortion of the display due to projector position, enabling effective use in diverse settings ranging from small meeting spaces to large conference rooms and classrooms.
HDMI terminal
These models are equipped with an HDMI terminal that can transmit digital audio/video with only one cable. It enables AV devices and PCs also equipped with an HDMI terminal to be easily connected to the projectors, which can then project the contents with no loss of quality.
Wide picture in real display (XJ-A255/250/A245/A240)
Able to accommodate WXGA Real display at 1280 x 800 dots (16:10), these models can display wide presentation materials and images in real size.
Wireless communication with PCs (XJ-A255/A245/A155/A145)
These models can communicate wirelessly (IEEE 802.11b/g) with up to four Windows® PCs, enabling meetings in which multiple PCs are brought together and presentations that can be conducted easily and remotely from a location away from the projector.
USB 2.0 host function enables presentations without a PC (XJ-A255/A245/A155/A145)
These models can project presentations, spreadsheets, word-processor documents, PDF files and other data* prepared on a PC, still images (JPEG/BMP), and moving images (AVI format: Motion JPEG) all without a PC just by using commercially available USB memory. They can also be connected directly to the Multiprojection Camera YC-430, which can project non-digitized information and even three-dimensional objects onto the screen.
The projectors can also be fixed to the ceiling with separately sold metal ceiling-mount fittings.
* As of January 7, 2010. According to a Casio survey.
* Requires conversion with included PC software.

| The Optoma EP910 is listed at 3500 lumens. What I like about the Optoma EP910 is that it has horizontal keystone adjustment so that it can be mounted off center and flank my stack. You can't notice any degradation in sharpness. Here is a older picture with two Sony HS20 projectors flanking the three Optomas stacked vertically in the center of the ceiling.
The three Optomas use basically the same 1.0" DLP lamp, either BL-FU300A or BL-FU300B
