High Brightness; Each standard LED optical output is 5mW ~ 15mW; the optical output of each LED Array component is 5W~20W. - Small Size; The LED Array is a highly integrated component TR IR illuminator shape is extremely smaller than the common products. Variable IR Light Angles Most common IR products' half intensity IR light beam angle is 7° ~10° which can only cover a small area. TR IR Illuminators have the variable angles from 5°~120°which significantly increases the coverage. The "flashlight effect" -the center of picture is too bright and the other part is dark was resolved. No other product can do this at present. Long life span The life span of LED Array is 50 000 hours and the common LED's is 6 000 hours. - High efficiency; The LED's is 10% and the special designed LED Array's is about 25%.
