We encourage our clients to purchase products that have the least environmental impact. We seek to incorporate environmental considerations into decision making at all levels.
I’ll try and break down the differences in the projectors, but let me chat about Mercury a little because that is what lamps (bulbs contain).
As you well know, Mercury vapors are VERY toxic! They contaminate immediate environments and poison its inhabitants. For this to happen, projector lamps have to be exploding on a regular basis. There is probably more Mercury on tuna than there is in one lamp.
Now I mentioned above that projector lamps have to be exploding on a regular basis for such contamination. That is true, however, when lamps are at the end of their life, they are more susceptible to cracking or breaking…so there’s that danger or risk. Not to brag, but our technicians do a great job of keeping track of lamp hours so as to prevent such an event. We monitor the hours, send reports to our clients, and remind them when it is time for replacement. Go KMT!
Personally and professionally, I don’t believe there is any real concern about Mercury contamination on personnel or habitation, based on where your business is located. Up to 0.025 mg/m(3) is acceptable. To give you some idea of how low that is, when a projector lamp explodes and billows in the air, approximately 30 mg or Mercury is released…and it lingers. When projector lamps don’t explode, there is no danger.
SONY LASER LIGHT PROJECTOR LAMP FREE
Power consumption is between 426 and 449 watts (your current projectors are using 480 watts).
The resolution is 1,920 x 1,200 dots (great resolution!)
It is said to be maintenance free for up to 20,000 hours, but hours vary depending on the usage and environment. That’s the challenge.
Also has energy efficient functions; instant on/off and nicely bright.
PANASONIC PT-EZ570 SERIES
MINIMAL MERCURY EXPOSURE
5000 LUMENS (your current projectors are 5500 LUMENS)
Companies today are extremely conscious of the environment AND have an obligation to President Obama’s Executive Order on Federal Sustainability (EO 13514) .
Companies are manufacturing equipment that is environmentally friendly and that meets Energy Star® requirements.
As a result, Panasonic has brought us the “Ecology Conscious” Projector(s).
Power consumption is 519 watts, but, there is an ECO standby mode which makes it 0.5 AND a network standby mode reducing the consumption to 12 watts. These are eco friendly features.
The resolution is 1,920 x 1,200 pixels (great resolution!)
I hope this helps in making your decision. Remember that “sustainable” and “sustainability” mean to create and maintain conditions, under which humans and nature can exist in productive harmony…for future generations.
Until next time…
