Projector technology is finding a new lease on life in classrooms and business boardrooms, as they are now frequently used to display desktop computer slideshows and other presentations. Although the technology has evolved in recent years, bulbs used in projectors remain fragile and expensive. To save money in these cost-conscious times, finding ways to extend the life of projector light bulbs is an important task for facilities managers.
Follow these tips for extending the life of projector light bulbs:
- Be careful when inserting bulbs into their sockets. Use a cloth or towel to handle the bulb, because oil on your skin does not react well with bulb components. Also, avoid bumping the bulb as you install it.
- Power down the projector when it is not in use. If the device has a cool down mode, use it before shutting the projector off. The cool down mode will help the bulb avoid the shock of rapidly cooling down.
- If you’re not going to use the projector for awhile, unplug it. This will help avoid power surges. Also, unplug the projector during electrical storms, as lightning strikes can cause power surges that may damage the projector.
- Make use of the projector’s economy mode, as it will reduce the brightness of images on-screen and help extend the bulb’s life.
- Let the projector bulb cool down before relocating the projector. 30 minutes usually is long enough.
