Seoul 3.5W Star LED (P4 Version)
Z-LED P4 series, similar to LUXEON Star LEDs
SEOUL Star LEDs are alsmost similar to the LUXEON Star LEDs and belong to the worlds brightest high power LEDs and most popular solutions for evey application based on semiconductor illuminants, too. The new P4 series is the new semiconductor STAR and a hard competitor to Luxeons K2. Depending on the forward current the P4 can get more than twice as bright as the K2 can. The Lumen/Watt ratio is currently unbeatable.
Please note
You should fortified take care of the different selections (bin codes) od the LEDs. For example: White LEDs of Rank "U" have a luminous flux of about 91 till 118.5lm and lower ranks a lot less (@ 1000mA). These differences and the later light efficiency of your application can thereby highly fluctuate. The low forward voltages (Vf) assure a low development of heat that benefits a maximum live time of the products.
