Do uv lamps use a lot of electricity?

However, the reality is that UV lights don't consume as much electricity. UV lamps are actually quite dim, so there is no high-powered durian. On average, operating a germicidal UV lamp inside your air conditioning system costs about 7 cents a day. Do UV lights consume a lot of electricity? Well, not really. It depends on the wattage of the bulb.

A 100 W UV bulb consumes approximately 0.5 kWh of electricity per year. So yes, it consumes a little electricity, but it's still a good investment. Therefore, if you want your UV bulb to be as cost-effective as possible, we recommend that you go shopping and try to select a bulb that is an “Energy Star” product. Typhon has developed an easy-to-use data acquisition and analysis tool (DAAT) that will collect the available flow and UVT data used by the installed UV system and will also monitor the energy consumption of the installed system using CT clamps. An optimally efficient configuration of UV LEDs in a water treatment system will be the first to compete with UV Hg and will maintain its advantage as UV LED performance improves.

The investigation of this installed LP Hg UV system was of special interest to the end user, as they perceived that there was a constant overdose and, therefore, did not meet the requirements of disinfection with UV rays ineffectively. The efficiency of wall outlets (WPE) is normally used to measure the performance of a UV lamp, comparing the input electrical power with the UVC output power to obtain a measure of the efficiency of the source of light. The objective of the research was to collect sufficient data to be able to carry out a side-by-side comparison, using the real, instantaneous and UVT flow, between the actual energy consumption of the installed UV Hg system and the calculated energy consumption of a Typhon B-310 UV LED system. Typhon is starting a program to explore a wider range of site conditions and make comparisons with a wider range of Hg UV systems to help water companies understand their current UV assets and how the adoption of UV LEDs could help them move towards a more cost-effective and environmentally friendly UV disinfection solution and to support the campaign towards net zero carbon emissions.

UVA bulbs emit wavelengths between 315 and 400 nm, while visible light bulbs emit wavelengths between 400 and 700 nm. This wavelength is between 290 and 315 nm, so UV bulbs usually be referred to as “UVC” or “UVB”. For many in the UV water treatment industry, UV LEDs are still considered a dream of the future, not yet ready for applications on a municipal scale, limited by the low power and low efficiency of the LEDs currently available. Municipal Scale UV LED technology has already been installed on 3 continents: Metawater and Aquisense in Japan and the USA.

USA, respectively, and the first commercial installation of a UV LED system by Typhon in the United Kingdom. The question that then arises is, as the efficiency of LEDs continues to improve, when will a UV LED system be able to compete with a UV Hg system in terms of energy consumption. At the ends of the design, the UV LED system uses much more energy to achieve the same result as the UV Hg system: 1.8 kW compared to 0.93 kW. At the time, it was understood that the technology was nowhere close to being ready to take on that challenge and that significant advances were required in both LED technology and reactor design to create the right environment for a UV LED system to compete with traditional low-pressure (LP) and medium-pressure (MP) Hg lamp systems.

When UVT increases, water quality improves and less energy is required to reach the UV dose, and the way in which the UV LED system follows both profiles indicates that the LED system reduces and adjusts much more quickly.
