Laser Projector Vs Lamp

There s still some variation from one model to another though.

Laser projector vs lamp. A modern day dispute amongst home cinema owners. Laser projectors are typically brighter than their lamp based counterparts. Without even taking into account the lower maintenance costs and electric savings the laser. Keep in mind that brighter isn t always better.

This should be a fairly easy one to answer. Lamp based single chip projectors typically pass their white light source through filters most often presented as segments in a translucent. A laser projector priced at 1 200 costs several hundred dollars more than a comparable lamp projector. There s a lot of jargon thrown around in this dispute and the expectation of understanding all of it is high.

Disadvantages of laser projectors vs. Affordable laser projectors use blue lasers and a mechanical phosphor wheel to make necessary colors while very high end laser models use sets of red green and blue. A lifespan of 20 000 hours is common for laser projectors whereas the lamp life on a lamp projector can be as low as 2 500 hours. What primarily separates laser from led is that laser projectors can be purchased with higher lumen output up to and potentially beyond 30 000 lumens which means large venues can now take advantage of the long term lower cost of ownership that solid state light engines bring.

While there is normally a single lamp in projectors lasers have many individual laser lightbulbs there can be as many as 24 and often 48 individual bulbs for output. A quality laser projector can range anywhere from around 3 000 4 000 lumens on the low side to as much as 20 000 lumens or more. When you hear the term laser projection you might think of that scene from real genius where they shoot a high powered laser at a house that is filled with up popped popcorn. If you have a fixed budget you might be able to purchase only 5 laser projectors of a given brightness and feature set compared to 7 or 8 or in some cases 10 lamp based projectors.

Unfortunately high powered popcorn popping laser technology isn t widely available yet. That of course is a critical decision in some companies and schools. Laser projectors come with a much longer lifespan and come with the added benefit of not having to regularly change the lamp. The obvious disadvantage of laser projectors today is the higher upfront costs.

The projector is rated to last for 20 000 hours of use so it can run for 12 5 years if it s used for 8 hours a day.
