L.J. Star Announces New Sight Glass Lighting Handbook

Engineering Handbook Is a Valuable Tool for Specifying Sight Glass Lighting

TWINSBURG, OH--(Marketwire - Jul 19, 2011) - A new 20-page application handbook from L.J. Star provides specifiers extensive technical information and guidelines to aid in choosing the ideal sight glass lighting for an application. The illustrated "Understanding and Specifying Sight Glass Lighting Application Handbook" spans the full scope of the subject including lighting technologies, determining the appropriate light output, measurement, wattage requirements, and environmental considerations.

Sight glass lighting is essential for the inspection and maintenance of vessels and pipelines in food and beverage, chemical and pharmaceutical processing plants. When deciding upon a proper light for an application, it is important to consider all of the properties of the light. The type, voltage, wattage, mounting configuration, and light pattern are all important factors, along with energy consumption, location requirements (i.e. hazardous), heat output, and vibration. This handbook covers all these considerations so that specifiers can choose the ideal sight glass lighting solution.

After a general introduction to types of light sources and their key characteristics, chapters include more detailed discussions of application considerations. These include an in-depth look at the measurement of light, determining how much illumination is needed, and mounting options. Readers will also learn how to specify explosion-proof lights required for hazardous environments. In addition, there are many helpful reference charts for temperature classes, NEMA and IP Ratings, as well as a checklist of the minimum information required to specify the appropriate light for a specific application.
