Seoul Semiconductor Co., Ltd. is a Korean company that produces LED's. Their P4 and P7 LED's are used in a number of flashlights. 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 asa Luxeon 3. It had the same die height and beam pattern as the Luxeon 3 which the then new Cree LEDs did not. | |||

Forward voltage: I and J are common. I is 3.25-3.50V and J is 3.50-3.75V, again with some overlap possible. | Forward voltage: I and J are common. I is 3.25-3.50V and J is 3.50-3.75V, again with some overlap possible. | ||
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 lenses. | |||
