10pcs High Power LED Chip 3W COB LED Emitter UV 3W.

I was looking for UV Leds, in order to convert an ordinary 4 led lamp into a UV lamp. In this way, I have bought these leds and replace them on the respective lamp. The result may be appreciated on attached picture. I was expecting a little bit more power of the leds and the generation of an illumination quite similar to night clubs “black” lights, what I have only achieved partially. The delivery was very quickly, about two weeks. I will continue my searching, in order to try to find a led array that provides me a best result, in this way.
