A projector is a great investment for many individuals and their families. Compared to traditional flat-screen televisions, projectors provide bigger screens and lower operating costs. That said, projectors do require some maintenance, depending on the model. The following guide provides tips and tricks on how to maintain a quality projector.
When choosing a projector, it’s important to understand how different types of projector lamps can impact maintenance requirements. Projectors work by shining a light through a transparent digital screen. While this digital screen doesn’t require any maintenance, the light bulb behind it may need to be replaced every few years.
Halogen light bulbs use a filament to generate light. Before 2005, most light bulbs used in the United States used a filament to generate light. However, most bulbs now sold are CFL or LED. Both of these technologies improve bulb lifetime and reduce energy use. Unfortunately, the light produced by these newer bulbs doesn’t always appear the same as older halogen-style bulbs.
Halogen projector bulbs have an expected lifespan of 1,000 to 3,000 hours. Since these bulbs generate significant amounts of heat, the filament inside the bulb wears down over time. In addition, these projectors often require a fan to reduce the case temperature. If this fan stops working, the projector may overheat or malfunction.
CFL bulbs do not produce enough light for use in a projector. However, some newer LED bulbs do generate adequate light. LED lamp use significantly less energy than a halogen bulb. In addition, they don’t generate as much heat. A projector with an LED-style bulb will never need replacement. That said, there are some significant downsides to LED bulbs.
Most LED bulbs can’t replicate the full spectrum of light found in a halogen bulb. Instead, they only project a tiny slice of the light spectrum. For some film aficionados, LED-based projectors make a movie appear washed out. That said, LED projectors are a good choice for those with a tight budget.
Replacing a halogen bulb can be very expensive. In many cases, halogen replacement bulbs for a projector can cost hundreds of dollars.
There are several ways to improve the lifetime of a halogen projector bulb. It’s important to make sure that the projector is turned off when not in use. In addition, the unit should be elevated off the ground. If a projector is near the ground, the air intake vent can suck in lots of dust, increasing the risk of mechanical failure and other problems. By following these simple tips, you can easily maintain a projector in great condition.
