Let There be (More) Light!

You may remember the old story about a man who is looking for his lost keys beneath a streetlamp. A passerby asks the man if he is sure about where he dropped them, and the man says, “Actually, I think I dropped them in the grass over there.” The passerby asks, “Then why aren’t you looking where you dropped them?” The first man answers, “Because the light is better here.”

On a street corner or in a processing facility, sufficient light makes all the difference in spotting what you need to find. The interiors of vessels and pipelines are typically far too dark to allow operators to observe important stages of their process readily through a sight glass. Flashlights usually don’t cast enough light and often produce glare, complicating the inspection process. Luminaires mounted onto sight glasses offer a more effective solution. Many processes take place in hazardous environments where explosive conditions may be present. For these applications, explosion proof lighting combines safe interior illumination and glare-free viewing.

There is a wide variety of explosion-proof sight glass lights to choose from. When choosing a light for a specific sight glass application, consider factors like type of technology, size, weight, voltage, wattage, materials of construction, mounting configuration, and light pattern. Energy consumption, location requirements, heat output, ambient conditions, and vibration must also be taken into account.

The “Understanding and Specifying Sight Glass Lighting” handbook addresses these considerations to help specifiers choose the most appropriate lighting solution for the application. Download your free copy today: http://www.sightglassblog.com/blog/03.html.
