Coming soon to a projector near you… HLD (High Lumen Density), a new LED solid state light source developed by Philips Lighting and branded under the trade name of ColorSpark.
A new digital projection technology that removes the need to turn off lights or close curtains, Philips ColorSpark is 3X brighter than existing LED projector technologies
This technology breaks through the Etendue limitation of current LED projectors that have limited their light output. HLD technology now allows projectors to reach the 3000 ANSI lumen level with the prospect to reach beyond 4000 lumens in the future.
In early 2016, the first announced projector brands, Optoma and Hitachi, will bring HLD-enabled projectors to market with more than 3000 ANSI lumens.
