Laser/LED Projection
Technologies for Worship Magazine: There's an unhappy secret behind the technology you're using to project hymn lyrics and mission videos. Projection lamps contain mercury, and unless you dispose of them properly, that mercury can leach into ground water and cause a host of health problems.

This sounds like a really cool illumination system. It makes a lot of sense to use a laser to produce green light instead of LEDs since green LED sources are less effective. I'm interested in learning more about the phosphor that can convert blue laser light to green light that is similar to what the LEDs produce. Although 4,000 lumens isn't incredibly impressive, I think that as LED and laser technology develops, we will be able to produce brighter and brighter projectors with this illumination system.
This sounds really neat! I wonder if the technology will catch on or not and how costly this projector is. What really struck me as I read this article is that this projector can produce 16.7 million different shades of color. I have a hard time even fathoming the fact that so many colors exist! The ability of this projector to reproduce so many different colors seems to speak highly for its accuracy. If this projector is cost effective and easy to install, I am sure that it will catch on and this technology will develop even further and be able to be implemented in a way that can produce more than 4,000 lumens. It's a great idea, and getting rid of mercury-filled bulbs is the best for the environment and the future!
One day everything will be LED. Combining the effectiveness of LED and Laser illumination create a steller foundation to build on for the future of projections. I agree that 4k lumens isnt killer - but there was a time when it was. So if we are already to this point with futuristic projectors I am optimistic about the future of this field. The lifespan of 20k hours is really, really impressive and I cannot wait for the day where projector lamps are not an issue. The thought of igniting a projector taking off somewhere around 8 hours off its life is such a waste. Oh, going green is good too.
