What I want to know is if this means no more replacing bulbs every 3000 hours.]]>Aug 30th 2008 9:26AMhttp://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/http://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/Aug 30th 2008 9:43AMhttp://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/http://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/Aug 30th 2008 9:38AMhttp://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/http://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/Aug 30th 2008 9:56AMhttp://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/http://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/
Also how long before you need to recalibrate the projector? WIth bulbs they claim for example 3000 hours lamplife, but for perfect viewing you need to calibrate your projector every so hundred hours, and with 1000 hours on the lamp you already notice a very big difference in intensity compared to the first few hours (so by the time you arrive at 3000 there is no visible image left)..

I certainly do applause these kinds of beamers (especially since they claim to be even much more quite than the current bunch (not that I notice my own beamer (optoma h79) when viewing a movie and sitting only about 1 meter from it))..
My next projector probably will be a LED based projector (since my current one isn't full HD 1080p), BUT I'd also like to see a LED replacement for my current bulb...

Also one of the most important information hasn't been revealed yet, and that's how much (real) lumens the frontprojector is producing.]]>Aug 30th 2008 9:59AMhttp://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/http://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/Aug 30th 2008 10:52AMhttp://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/http://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/Aug 30th 2008 3:07PMhttp://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/http://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/

Brightness will get better on LED-based displays, the theoretical peak efficiency is about three times what we are achieving at present.

LED's though almost as efficient as an HID or flourescent, still generate a good amount of heat. They are basically silicone and will quickly destroy themselves at temps around 150 C (slightly more than boiling water). They need cooling to protect them.

As LED's transition to conventional lighting uses, expect to see very large heatsinks when LED's show up in your household lighting. They may try to disguise it and build it into the fixture, but it won't be small!]]>Aug 31st 2008 1:14AMhttp://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/http://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/]]>Aug 30th 2008 11:10AMhttp://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/http://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/
Here's hoping that this equates to "maintenance-free" use of this kind of projectors (we've busted quite a few bulbs in school recently.)]]>Aug 30th 2008 2:01PMhttp://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/http://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/Aug 30th 2008 4:26PMhttp://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/http://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/Aug 30th 2008 10:09PMhttp://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/http://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/Aug 30th 2008 11:54PMhttp://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/http://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/

This is the best news i have ever had if you love projectors like me. Last week I replaced my bulb (only 1500 LUMENS and 2000hrs bulb) for my Panasonic PT-AE2000 for £250 quid, thats expensive yo especially when i use that projector as the main TV for everything not just movies.

I CANT WAIT FOR THESE LED PROJECTORS TO COME OUT ON THE CHEAP BEFORE MID 2009.]]>Aug 31st 2008 1:28PMhttp://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/http://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/Sep 1st 2008 12:21AMhttp://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/http://www.engadget.com/2008/08/30/texas-instruments-new-led-based-dlp-projection-shines-in-person/Sep 2nd 2008 12:42PM
