The P4 uses [[Cree]]'s EZ1000 die and has similar performance to the Cree XR-E LED. Do not confuse the Cree P4 bin (brightness) with the SSC P4 LED. The SSC P4 LED was much used as a "drop in" replacement for Lumileds Luxeon 3 LEDs. It gave about twice the output for about three times as long on the same battery and driver as a Luxeon 3. It had the same die height and beam pattern as the Luxeon 3 which the then new Cree LEDs did not. | The P4 uses [[Cree]]'s EZ1000 die and has similar performance to the Cree XR-E LED.

The dies are manufactured for SSC by Cree, but the phosphor is SSC's own. Many prefer the P7 to the Cree MC-E which has the same dies but different phosphors and optics. | The dies are manufactured for SSC by Cree, but the phosphor is SSC's own.

==Tint bins== | |||
[[File:Ssctints.jpg|thumb|400px|SSC's tint bins]]SSC does not use the [[ANSI White]] standard, but comparisons can still be made by using the color temperatures shown on the chart at the right. SVN is not on this chart, but has a CCT of 5350K. For more information on binning see the Binning and Labeling guides available at the product links listed above. | |||
