PRODUCT SPECIFICATION DATE: 11/27/2006 cosmo H.P LED : NO. 61L70027 KLE00WXX1 ELECTRONICS CORPORATION SHEET 1 OF 6 REV. 1 1. Features Cosmo’s high power LED packages can handle up to 350-500mA DC current,. These packages are formed by bonding 1 pcs LED chip on a Φ8mm Emitter. The main features of these packages are as follows： Very high flux output per LED. Very long operation life time up to 100k hours attainable, by using a proper heat sink. 120±10o cool beam in most packages. 2. Applications Outdoor and indoor architectural lighting Reading light (car/bus/aircraft) Decorative/entertainment lighting Bollards/Security/Garden lighting Traffic signal Portable lighting (flashlight/bicycle) Edge-lit signs (exit sign/point of sales) LCD backlights Light guide 3.
