The primary light source technologies used in projectors are:
* Lamp
* Laser
* Laser-Hybrid

lamp is excellent for situations that demand high brightness and more accurate colors.
A lamp has very high luminous efficiency and high light emission.
A lamp is the optimal option to provide an accurate HDR result.
LED (Light Emitting Diodes) provides very good colors, low noise, low power consumption and less heat than other options.
LED is frequently used for portable projectors, even though the LED has limited projection brightness.

laser is the selected choice for large venues without sacrificing brightness, color saturation or image quality.
A laser provides high light output. The light travels in a straight beam with minimum divergence. The impact of the environment is minimal.
A laser offers maintenance free operation, lower heat generation and a non-standard angle mounting ability.
laser-hybrid is a combination of LED and laser technologies.
A laser-hybrid utilizes the advantages of LEDs. It boosts the brightness, but the color quality can be mediocre.
A laser-hybrid is maintenance free.
What is the right choice?
Each light source solution has advantages and disadvantages, depending on the application and the required functionality .
A few questions to consider to avoid buyer’s remorse and to ensure a happy customer:
  • How many hours the projector will be used every week?
  • What is the content that will be mostly displayed (text, images/movies or a mix of both)?
  • What is the required resolution?
  • Where will the projector be mounted? Bear in mind that regardless of which technology is selected, the projector’s filter must be cleaned at least once in a while.
  • How is the ambient lighting?
  • How many lumens should be considered?
  • How large is the projection screen?
  • What screen material will be used or is available?
  • What is the budget?
