[High-tech LED] US LED manufacturer Sensor Electronic Technology Inc (SETi) has launched UVTOP275, a deep-UV (UV) LED product with a lifetime of more than 10,000 hours, far exceeding other traditional UV sources.
According to SETi, the life analysis is based on the standard procedure of SETi: at room temperature (about 23 ° C), driven by 20 mA DC, the LED has no heat sink or no heat treatment, the test is about 2000 hours, the power output is reduced to the initial power. 50% (L50). According to the test results, UVTOP275 has a life of more than 10,000 hours.
The LED light range produced by SETi ranges from 240nm to 360nm. Its products have passed the ISO9001 quality system certification and are the leading international LED manufacturers with a wavelength below 365nm. Although SETi does not release the longest life of its products in the UVTOP product specification, UVTOP275 is expected to have a life expectancy of nearly 5,000 hours under L50 conditions, and SETi is still developing and testing LED products with longer life.
It is reported that SETi predicts the life of LEDs by measuring several batches of products according to statistical principles. The measured LEDs are packaged in a windowed TO-39 metal glass measuring device for overload experiments, and the average output power is 0.8. mW, the emitted light has a wavelength of 280 nm ± 5 nm.

It is single signal transmission programmable led pixel strip. Only with One Data wire. the same as WS2811 and SK6812
But It is difference,the WS2812B is just addressable individually, IC just inside on the led.just have DC5V Working Voltage,can be control by extend controller to achieve the flash, movies and so on, Indoor and outdoor is suitable.
It is the most common single control led strips.
