This high powerCOB LED,white,20 Wattsis intended fordesignswhere a high brightness is needed. Theyareavailable in bothwarm white (3200K3000 ...) and white(6500K6000 ...somethingcool white),and thatat20wattsand 40watts.
The LEDsare selected onebyrelalieflow driving current(600mAand 1200mA)at aforward voltageof about32 V. As with every COB LED you required an appropriate LED current driver.
TheCOBLEDdefinitelyneedagood cooling,an aluminum heatsink oraluminum housingofsufficientsizeis a must. The thermalresistance of the heatsinkmust be at least2.5°C/W, alowervalue may also choosed.
