With the introduction of lamp-free projectors that use Lasers & LEDs as a light source instead of lamps, you can now get projectors that provide the same high brightness and vibrant colors without the need to ever change a lamp. The new Laser & LED light sources degrade at a much slower rate than lamps and so maintain their brightness for a much longer time. Most Laser projectors are rated as having a lengthy operation life-time of up to 20,000 hours. This means that in a typical university environment, your lamp-free projector should last over 12 years, based on an average of seven hours of use a day, and 220 school days a year, that’s without ever having to change a lamp!
What does this mean for you? It means that a 4000 lumen lamp-free projector is going to stay near 4000 lumens for the majority of its long 20,000 hour life, unlike traditional lamp projectors, where the lamps start to degrade immediately and can lose up to 50% brightness between 2,000 and 3,000 hours of use. If you do the math, that 5000 lumen lamp projector will be projecting a brightness of only 2500 lumens after a only a couple of years of use while the new laser projectors are keeping your images bright and clear for well over 10 years. 4000 lumens lamp-free projectors can provide the reliable high brightness needed for higher education’s large classrooms and most lecture halls for years and years with minimal maintenance.
And it gets better as there are numerous benefits gained from using Laser light source projection technology.…Read More
