When coupled with the PowerLite W6, the PolyVision eno is a powerful tool for these trainers who are constantly on the go and setting up in various room configurations. PolyVision bills the eno as the first three-in-one interactive whiteboard solution because it behaves like a dry-erase marker board, a magnetic board, and a multimedia surface all in one. The board can also be moved from location to location without cumbersome cables or power hookups. According to the company, the eno provides interactivity via a Bluetooth-enabled stylus that requires no hard connection to power or data, and therefore no extra training for teachers.

The virtually indestructible board also offers a green benefit since its e3 environmental ceramicsteel surface has Cradle to Cradle Silver certification from McDonough Braungart Design Chemistry (MBDC). The Cradle to Cradle certification ensures that the product uses environmentally safe materials and is designed for recycling or composting and energy efficiency.

Another green aspect to the donation is Epson’s proprietary lamp technology called Epson Twin Optimized Reflection Lamp (E-TORL). “It is an optical assembly with more efficiency so you can run the lamp longer and cooler, amounting to cost savings over time,” Oey says, referring to the elliptical (versus parabolic) reflector in the assembly.

According to Epson, using E-TORL technology means that lamp life can last up to 4000 hours in economy mode, up to 50 percent longer than competitively priced models. The company also notes that replacement E-TORL lamps cost up to $150 less than competing replacement lamps. Sources say that the E-TORL design gives the projector a 20 percent improvement in efficiency by redirecting errant lights onto the optics and by reducing waste heat.

Oey says the PowerLite W6 is more like a traditional projector and that, in a classroom install, teacher would most likely have a PowerLite 400W multimedia projector instead. According to Oey, the 400W is a short throw projector that can be mounted close to the wall, which saves space and reduces glare from the board. The 400W also have networking support capability so administrators can monitor lamp life. “The key is that Epson is the leader in the market,” Oey says. “We have a range of product with unique features that fit whatever the market needs.”
