Various manufacturers have produced handheld projectors exhibiting high-resolution, good brightness, and low energy consumption in a slightly larger format than pico since 2008. However, most handheld LED projectors, as of December 2017, have been widely criticized for having insufficient brightness for everyday use in a normally lit room.
ANSI lumen measurements are in general more accurate than the other measurement techniques used in the projector industry. [16] This allows projectors to be more easily compared on the basis of their brightness specifications. The method for measuring ANSI lumens is defined in the IT7.215 document which was created in 1992.
Video projectors use a very bright ultra-high-performance lamp (a special mercury arc lamp), Xenon arc lamp, metal halide lamp, LED or solid state blue, RB, RGB or fiber-optic lasers to provide the illumination required to project the image. Most modern projectors can correct any curves, blurriness and other inconsistencies through manual settings.
The PhlatLight LEDs are also used in a new class of ultra-compact DLP front projector commonly referred to as a "pocket projector" and have been introduced in new models from LG Electronics (HS101), Samsung (SP-P400) and Casio (XJ-A series). Home Theater projectors will be the next category of DLP projectors that will use PhlatLight LED technology.

Color Light Output (CLO), also known as Color Brightness, is a specification that provides information on a projector’s ability to reproduce color. Color Light Output is specified in the lumen unit and measures a color projection system's ability to correctly reproduce color brightness.
