Insect electrocuter units rely on black lights to attract insects with ultraviolet (UV) light. The special safety coating on Shat-R-Shield Black Lights
makes it possible to place "bug zapper" units in the workplace where unprotected glass is prohibited - critical for the food processing industry.
Black Lights should be replaced after 7,000 hours. At this point, UV light deteriorates to levels ineffective to attract insects.

Shat-R-Shield shatterproof / shatter-resistant Black Lights / Bug Lamps are coated from end-to-end with the patented, plastic safety coating.
The coating reduces light output by only less than 1% and is a minimum of 16 mils thick. If used properly under warranty criteria, the coating
is guaranteed not to yellow, crack or flake for the rated-life of the lamp.

If a Shat-R-Shield fluorescent lamp is accidentally broken, virtually all glass, phosphors and mercury are safely contained within the clear and tough, skin-tight plastic coating.
