850nm Infrared LED - 3014 SMD LED

3014 SMD LED - 850nm LED - 0.3W:

5. The 850nm LED(850nm SMD LED or 850nm Through-hole IR LED) has a red burst and the 940nm LED(940nm SMD LED or 940nm Through-hole IR LED) does not have a red burst. The so-called red burst refers to the visually visible red dots on the chip when the infrared lamp is working. So if you need to hide, use the 940nm LED is a good choice, but some The customer will use the black colloid 850nm to cover up the red burst situation, but if you pay attention to it, the red burst is still visible.
5. The radiation intensity of 850nm LED is about 2-3 times higher than the radiation intensity of 940nm LED. If the radiation intensity is high, the brightness will be higher.
5. In the incoming test, the 850nm LED can be judged by directly lighting it with a 1.5V battery, but the 940nm LED needs to be judged by a mobile phone or camera.
5. Under the same current condition, because the voltage of 940nm LED is reduced, its power consumption will be smaller than that of 850nm LED, so the chip with the same size can withstand a larger current than the current of 850nm LED.

5. As we know, sometime, we can't see the IR LED with our naked eyes, then how do we know if the infrared LED can work or not? 

850nm LED can't be like that normally colorful emitting light diode, if the testing current too high, the 850nm IR LED will be damaged by this current. 

Then the best way to do test is by the Special pointer universal meter for infrared light emitting diodes. Under the 10K resistor, connecting the black cable to the anode of IR LED and the red cable to the cathode of the IR LED, The measured forward resistance should be 20 ~ 40K normally. Then we changed the side, which is connecting the black cable to the cathode of IR LED and the red cable to the anode of the IR LED then The measured forward resistance should up to over 500K.
