UV-CCL Handling Precautions

UV Light :
While the UV-CCL is lit, do not allow direct contact with skin and do not look at the UV light without preventative eye-wear.
UV light not only affects germs but also resin and other organic materials.

Ozone :
Ozone is generated by the radiation of 185nm in this product. This is hazardous to human body as its concentration gets higher. When lamp is on, wearing protections such as mask are required. The maximum allowed output of ozone varies by country and /or region. We ask that you verify and control total output laws for your specific product.
*Ozone Threshold Limit Values:
  0.1ppm Japan Society for Occupational Health Recommended Value (1992), 0.1ppm (TWA) ACGIH (1992-1993) US Department of Labor (OSHA)

Mercury :
To emit UV light, mercury is included in our product. Per tube, there is less than 3.5mg of mercury.
Our mercury use is in accordance with RoHS and it's exempt from the Minamata Convention on Mercury.
It has been possbile to manufacture and sell the lamp after 2020.
When discarding lamp, regulations of municipality and countries where the final product will be discarded, shall be applied on.

Lighting circuit :
This product needs invertor (lighting circuit) for turn it on. The invertor is high voltage. Please do not touch the lamp and invertor under the switch is on. It would be cause of electrification.

Others :
Please do not dip this product in water. The water penetrate electric wirings and it would be causes of short and electrification.

What are UV-CCLs?

What are Ultra Violet (UV) rays?
UV is an electromagnetic ray wave spectrum from 100 to 400 nm (nanometer). This spectrum can be separated in UV-A, -B & -C. UV-rays are also part of natural sun light.

UV-A and -B is already well known causing suntan on people's skin after sunlight exposure. Knowledge of UV-C is less spread, because these most aggressive rays normally do not reach us through the protective earth's ozone "shield". Though fortunate for our everyday life, we can instrumentalize UV-C as most effective disinfectant leaving no such waste as e.g. chemical detergents.

Though established very well already e.g. in the medical industry, proper handling is crucial to benefit from UV-C application, while steering safe of any accompanying risk.

Disinfection Mechanism
When reproducing organic mater is exposed to UV-C rays (200~280nm) the DNA is ruptured. The damage inflicts on its reproductive capability.
This is called "inactivation". Bacteria irrespective of environmental media (air or water) discontinues to grow and existent stems wither. Disinfection with UV–C is in total considered much safer than using chemicals, especially for children and pets, plus no waste is left polluting the environment.

Characteristics of Stanley's UV Cold Cathode Lamp(UV-CCL)
'Hot Cathode Lamps' (UV-HCL), called GL Lamp, application is widely spread in industrial fields. Though its radiant power is considerable, GL lamps size is big and lifetime is short. Mainly these are the reasons, why application in consumer products is so far limited.
Stanley is focusing its attention on these weaknesses to expand beneficial attributes attention such as the unparalleled disinfection of UV-C by releasing NEW UV devices in 2010. Product characteristics cover existing products disadvantages by featuring
Compact size    Long life    Power Saving    Vibration-proof
In response to heightened awareness to health concerns & environmental pollution Stanley Electric's products are also safely applicable to consumer products for deodorization, air conditioners and vacuum cleaner air purification.
