RGB pure laser outperforms laser phosphor illumination.
Fact 06

Although RGB pure laser and laser phosphor are both classified as laser illuminated projectors, RGB pure laser outclasses laser phosphor in terms of color gamut, brightness, contrast and operational life. This is in large part a result of system design. RGB pure laser features individual red, green and blue laser diodes with specific wavelengths allowing these projectors to be incredibly efficient. A laser phosphor projector only uses blue laser diodes and requires extensive filtering and color correction to achieve acceptable color. This difference in efficiency has impacts on color, brightness and operational life – making it very important to understand what you are getting when deciding which illumination platform to choose.

Laser phosphor RGB pure laser
Color Rec. 709, DCI-P3* Rec. 709, DCI-P3, and up to Rec. 2020
Brightness Up to 33,000 lumens Up to 60,000 lumens
Contrast 2,000:1 6,000:1
Operational life 30,000 hours to 50% brightness 30,000 hours to 80% brightness

*only with extensive yellow notch filtering and color correction which reduces brightness nearly 50%

Color gamut comparison

Bright, bold and vibrant colors can bring a movie to life! One of the major benefits of RGB pure laser is its ability to produce a wide color gamut, replicating Rec. 2020, which exceeds the DCI spec. Take a look at the charts to see how each illumination platform compares when it comes to producing colors.

Illumination type Color gamut Notes
RGB pure laser Rec. 709, DCI P3 and up to Rec. 2020 The only projection technology to approach full Rec. 2020
Xenon lamps
Some laser phosphor
DCI P3 Achieved with a Yellow Notch Filter (YNF)
Laser phosphor requires more aggressive filtering and color correction
Some laser phosphor Rec. 709 For non-cinema applications only
Size matters: Comparing RGB pure laser platforms

The Christie CP4325-RGB pure laser projector has a similar size and weight compared to our Xenon-based cinema projectors. What’s more, unlike the competition, our RGB pure laser cinema projector doesn’t use external chillers or racks, making it simple to install into pre-existing spaces, whether it’s a booth or boothless.
