First of all Foley, DLP does not have trouble with blacks. In general LCD has the poorest black performance, LCoS and DLP have great black level performance. It depends on which generation of product you're comparing, but DLP definitely would not be classified as having poor black levels. Also, the more powerful the bulb, the higher the black levels, regardless of the design.
Secondly, Engadget blogger and HTMag Editor, posting specs that don't really show the brightness of the projector does not help the consumer. "A brightness of 27 ft-Lamberts" measures the brightness of the projected image on the screen, which is a result of projector brightness AND screen size AND screen gain ratio. So, the ft-Lambert result you posted doesn't directly describe the performance of the projector. 27 ft-Lamberts is fairly bright (similar to a CRT television), but is it because of the projector or the screen?
Using this calculator ( http://www.carltonbale.com/ht/calculator/index.html ), you can backwards calculate the actual projector brightness. It requires an 800 ANSI lumen projector to produce that brightness level when using an 87" wide screen with a 1.0 gain (the screen used in the HT Mag test). Not bad at all for a calibrated projector, but not quite the light cannon the post makes it out to be.
