Boxlight has released a new, battery-powered LCD projector that uses LEDs instead of hot, expensive incandescent bulbs. A cluster of 10 bright white LEDs projects an image of 150 lumens, compared to 800-1000 for an entry level old style projector. The unit is not suitable for large groups or rooms, but its quiet operation (no fan needed) and small size (1 lb.) could make it a popular choice as a home or office projector, or impromptu small group business meetings. How many times have you been in a work situation where two or three people are clustered around a monitor, trying to look over someone's shoulder at too small print on the screen? This little device would be perfect for projecting a 40" image onto an office wall for small group meetings and collaboration. As these new designs are refined, light output should increase and prices will drop. And as a bonus, these things are very green, using a fraction of the electricity that other projectors do.
LED lighting options are proliferating rapidly, and we are going to see more and more applications for them in the home and office. The initial cost will be offset by the extraordinary long life of the bulbs and the energy savings.
