I have updated this article: "Actual UV-C Emission from a UV Bulb; Aquarium or Pond" Here is an excerpt: "Wattage of a bulb can be misleading. Watts used in a bulb is the power consumption of a bulb. A 60 watt bulb used 60 watts of power. The actual output of a bulb is directly related to the wattage. The higher the watts used, the great the power consumption. But what is noteworthy, is that the wattage though does not actually tell us how much useful output the bulb has, or how efficient it is. The efficiency of the bulb is the actual output of the bulb. Specify speaking about UV-C bulbs, they have a light energy spike at a certain wavelength of light (254nm). This light energy is what sterilizes. With any UV-C bulb, there will be an energy spike at this lighting level as well use some of it lighting energy on other parts of the lighting spectrum. The light emitted at the UV-C namometer of light is the useful energy or wattage used from the bulb. The other energy emitted on the lighting spectrum that is not UV-C is essentially wasted energy. Therefore the wattage of the lamp is not the same wattage being emitted of UV-C. A 30 watt UV bulb does not emit 30 watts of UV-C. Take a look at this picture which shows the energy spike of a UV bulb. At this spike, light energy has sterilizing abilities."

I updated this important article from one of our less known web sites for aquarium/pond keeping information " High Output UVC Emission from a UV Bulb/Lamp; Aquarium or Pond Here is an excerpt from the overview of this short article: "This efficiency is what becomes important as we look for a replacement for our UV Sterilizer/Clarifier or even a new UV Sterilizer as most of what is sold via the Internet or discounter brick & mortar stores are LOW OUTPUT medium pressure UV bulbs/lamps with as little as 25% of the UVC of the vastly better low pressure high output UV lamps sold but by a handful of high end sellers. So please read on and beware if the price seems too good."Carl
