These two new projectors from NEC are low maintenance! Their LCD light engines, coupled with NEC’s original sealed optical technology, eliminates the need for a filter. Instead of filters, the projectors use NEC’s unique cooling technology. No filters means low maintenance, which is a major plus for education and business environments, especially if installing a fleet of these projectors.
If you’re not familiar with the concept, having a sealed light path is beneficial in that it protects the optics from dust blobs – ugly, discolored blobs on your projected image, caused by dust settling in the light path. This prevents some potentially costly maintenance from being necessary.
The LCD light engine gives even greater benefits when it comes to maintenance, as the light engine has a lifespan of up to 20,000 hours. Though standard for light engines of this type, the LCD technology provides 8,000 to 12,000 hours more than the longest life spans of the best-of-the-best lamp based projectors. Though lamps are typically low cost, they need to be replaced every few years, which adds up in cost of materials and installation.
