LED germicidal UV Lights

I did some research into LED germicidal UV Lights, because an LED would require much less electricity than a regular germicidal UV light.  Unfortunately, LED germicidal UV Lights are a relatively new technology, are not easily available, this American Air and Water says "However at this time there is no UV LED equipment that can compete with the high output UV lamps in real world production conditions."  LED germicidal UV Lights are therefore, not the best course of action, and I will continue using regular germicidal UV Lights.
