SONY - LCD PROJECTOR LAMP VPL-PS10 / PX10 / PX11 / PX15
Price: $411.99
Sony VPL-PX11 is a little on the expensive side, or used to be, but the cash you put in definitely is going to be spent wisely.Sony introduced the VPL-PX11 back in 2002 and it had a marvelous two year production run. Consumers just couldn’t keep their projector loving hands off of them.The brightness of the projector lamp allowed for a gigantic image, 21 feet to be exact. The 200W projector lamp inside the VPL-PX11 was amplified to allow a brighter image without compromising screen size.The brightness of the projector can also be squeezed into a smaller image using the lens-zoom feature and you will not experience an over-saturated screen. As with most high-lumens projectors, the projector lamps does not last as long, and this particular one will last for 1500 hours. The most incredible feature about the VPL-PX11 is what I mentioned in the beginning, the quality of its instruments.
