LED Design Advantage

#1 DLP in the Americas

The ML300?s LED technology delivers low power and silent operation. The same LED technology provides vivid color, durability and long life that make it attractive to price-sensitive small business and consumer users. LED brightness lets users create larger images in rooms with more ambient light while still allowing for easy viewing. Featuring a wider color pallet, LED projector images appear to be brighter than lamp based projector images.

The LED light source has an estimated lifetime of more than 20,000 hours (equivalent to using the projector four hours every day for over thirteen years). LED is incredibly cost effective compared to lamp-based projectors. For example, users with a lamp-based projector would have to replace the lamp in the projector at least four times over 20,000 hours of usage?at a cost of over $800, compared to the completely maintenance-free LED lamp.

The LED-based design, in addition to being environmentally friendly with low power usage and the elimination of mercury and other hazardous materials, allows for cool operation which in turn allows for the compact size.

5 out of 5 stars   Overall small light and great.
By Aishman (RBS Israel) July 30, 2012
Review submitted for Optoma ML300 Mobile LED Projector, WXGA 1280 x 800 Resolution, 300 ANSI Lumens (OPML300)
Verified Purchaser
Pros: Quality Construction, Easy To Use, Small Footprint, Clear Display
Cons: Noisy
Other Comments: Nice and small and light projects clearly. I like all the connection options and that you can play videos straight for the projector, video files played directly from the projector have a limitation of the resolution of the projector 1280x800 so if you have hd files you must use q computer. Over I like it and like the the led will last long, only wish it were a bit stronger lumens but it's really not bad in a dim room and great in dark.
