There still exists two bottlenecks in researched and development of UV(UV-B and UV-C LED) led. the second problem is high price and low led output power. so that is become very difficult to business marking. but the uv led had improved somewhat, the uv led luminous radiation began expanding to 176.6mw. It really makes a big difference(in the context of the industry it is a big achievement.) we need to have some better explanation.
So now we try to analyzes comparatively the difference between characteristic parameters of different factory.

RayVio    45 mw
NIKKISO   50 mw
LG Innotek 15 mw
AsahiKASEI 20 mw
