Binning Structure
SST-08-UV LEDs are tested for radiometric flux and wavelength at a drive current of 500 mA, 20 ms single pulse at 25° C and placed into one of the following radiometric flux (F) , wavelength (WWW) and forward voltage bins. The LEDs can also be driven at other drive
currents, to achieve the correlated flux values listed in the table.
