1. 740nm , 850nm or 940nm means the wavelength emitted by the LED chip. They are infrared lights. First, they show different wavelengths.
2. Generally, the higher the wavelength , the lower the forward voltage drop VF under the same current condition. Under the condition of 20mA current, the 850 VF is about 1.35-1.55V, and the 940 VF is approximately between 1.10 and 1.25V. Of course, the VF differs depending on the current.
3. The 850nm has a red burst, and the 940 has no red burst. The "red burst" means the red spot visible on the chip when the infrared lamp is working. Therefore, if it is necessary to conceal the situation, using the 940 is a good choice, but some customers will use a black colloidal to cover up the 850nm red burst , but can't completely covered.
4. The 850nm radiation intensity is about 2-3 times higher than the 940nm. The higher the radiation intensity, the higher the brightness..
5. After testing, the 850nm can be judged by directly using the battery of 1.5V/W, but the 940nm requires the use of a mobile phone or a camera to judge whether it is normal or not.
6. Under the same current conditions, the power consumption of the 940 will be lower than the 850nm , so the same size chip can withstand a larger current than the 850nm.
7. 740nm can be used for infrared, can also be used for plant growth lights
