So you've decided to finally get that projector you've been thinking about for months. Or maybe you've already had one and want to upgrade. If you have been searching, I'm sure you've discovered that there are A LOT of options. Choosing the projector that's right for you and you environment can sometimes be a complicated process if you really care about what you're buying and also trying to factor in power consumption.
Just Some Thoughts to Get You Started
There are a few types of projectors out there that you can get your hands on. The differences in these usually depend on the source of light, the bulbs. There are LCD, LED, and DLP lamps and all have different characteristics that make them their own. What are the differences in these 3 letter acronyms, you may ask. Well that part is fairly simple.
The LCD (liquid crystal display) is the more of the traditional way of displaying content on the projectors. These types of projectors use what is commonly referred to as a lamp. But, over the last few years, the advancement of projecting and bulb technology has skyrocketed and deserves a mention. These advancements have produced bulbs such as the LED (light-emitting diode) and the DLP (digital light processing). These are definitely the more energy efficient ways to go!
LEDs tend to have a much longer lifespan. On average, they last up to 20,000 hours longer than LCD lamps. This makes the LED more reliable because it fails less often and doesn't burn out like LCDs. Another factor is, LCDs have very hazardous mercury inside them, which is not a factor with the LEDs. LED seems to already be the best option if lower power consumption is your number one goal. Also, The LED lighting systems provide a larger number of colors and also more saturated colors, making the picture appear brighter.
One disadvantage that the LED system has however, is the inability to be as bright as the lamp based systems. This would present a problem if you are in a room that you just can't get dark enough.
Digital light processing is a solid state technology and only uses a single device to produce images. This helps in the production by allowing manufacturers to make smaller, thinner projectors than the competitor systems, which require three devices to function. One big advantage that DLPs have over LEDs is that dust does not affect them. The biggest enemy with LEDs is the dust. The filter in an LED system needs to be cleaned very regularly, which is not the case with the DLP systems.
Regardless which projector technology you choose, make sure you look up the power consumption of your existing or future projector.
