Since the first LCD units were pressed into service as home theater displays, digital projection has suffered from one limitation, the bulb. No matter the technology – DLP, LCoS or LCD – all digital front projectors use either a UHP (Ultra High Pressure) mercury or xenon lamp as a light source. This presents several obstacles. First, the lamp has to be replaced every so often. It can last as much as 4000 hours but sometimes it’s as little as 1000. Secondly, the lamp shifts color and dims as it ages. In fact, I will usually replace mine at 1000 hours regardless of the rating due to the lowered light output. The color shift also requires re-calibration at regular intervals. I always recommend adjustments at 100, 400 and 800 hours to maintain the most accurate image. Third, lamps run hot requiring a constant-running cooling fan to keep the projector from overheating. There must be a better way.
Enter the Light Emitting Diode. At last year’s CEDIA Expo, LED projection was THE hot new technology for high-end theaters. The promise of a product with a 50,000 hour lamp life is one of the most significant advances in front-projection since the invention of the DLP chip. With LED technology, projectors can now be used as the primary display. There’s no waiting for warmup or worrying about power on/off cycles and its lifespan is equal to a flat panel TV. Not only that, the light level and color will remain stable for the life of the product. Is there a catch? Read on as we explore this potentially revolutionary technology.

Recycling your old electricals is easy!
Recycle your electrical and electronic devices free at your local recycling centre. To find your nearest centre, visit the Recycle More website and type in your postcode.
Why recycle?
Unwanted electrical equipment is the UK’s fastest growing type of waste.
Many electrical items can be repaired or recycled, saving natural resources and the environment. If you do not recycle electrical equipment will end up in landfill where hazardous substances will leak out and cause soil and water contamination – harming wildlife and also human health.
We’re proud to support your local authority in providing local recycling facilities for electrical equipment.
To remind you that old electrical equipment can be recycled, it is now marked with the crossed-out wheeled bin symbol. Please do not throw any electrical equipment (including those marked with this symbol) in your bin.
What is WEEE?
The Waste Electrical or Electronic Equipment (WEEE) Directive requires countries to maximise separate collection and environmentally friendly processing of these items.
How are we helping?
In the UK, distributors including retailers must provide a system which allows all customers buying new electrical equipment the opportunity to recycle their old items free of charge. As a responsible retailer, we have met the requirements placed on us by financially supporting the national network of WEEE recycling centres established by local authorities. This is achieved through membership of the national Distributor Take-back scheme (DTS).
