What is a Laser Projector?

What is a Laser Projector? -

Perhaps the biggest innovation to happen in the last few years is the development of affordable projectors that eliminate the need for replacement lamps.  This article covers why experts are recommending laser projectors – and addresses common questions for people who are buying a projector for a classroom or collaboration space such as:

  • Why are laser projectors better than less expensive lamp or laser hybrid projectors?
  • Why do laser projectors have better color accuracy?
  • Do laser projectors still have filters – and will they turn yellow over time?

 

Why is a laser projector better than a lamp based or laser LED hybrid projector?

The BenQ LX60 was first commercial laser projector for sale in the US market, and today the laser projector technology dominates the business and commercial market.   Why are laser based models so popular?

 

Laser projectors vs. lamp projectors 

The laser light source for projectors offers a number of advantages over replacement lamps.  The first advantage is that, for most models, you can run the projector at full power and use the projector for 10 or more years (20,000 hours) without having to replace the lamp.   This is especially advantageous for large deployments such as school districts, where the cost and availability of labor to replace hundreds of projector lamps can create both logistical and financial challenges to an organization. 

 

Laser projectors vs. LED laser hybrid models

Casio was the first company to create a laser / LED hybrid projector in 2010, which offered some of the same benefits as projectors with 100% lasers.  While this technology eliminates the traditional projector lamp, many models have warranty restrictions that limit the light source warranty to only 6000 hours.   Projectors using both LED light and laser light sources cannot achieve the same brightness levels as a 100% laser projector, and if used more than 10 hours per day and five days per week, only have a one year warranty.   Most laser projectors models do not have these types of usage restrictions.
