LED sight-glass light

By Yelena Shamis |

Illumination is required for visual inspection of a process through a sight glass in a vessel or tank. A newly demonstrated light source, developed by L.J. Star Inc. (Twinsburg, Ohio; www.ljstar.com) and marketed as the LumiStar3000, is said to be world’s brightest sight-glass light. The company says the product delivers 3,000 lumens of light, four times the brightness of a 100-W halogen lamp. And because it uses a specially designed light-emitting diode (LED) as the light source, the LumiStar3000 consumes only one tenth of the energy of a halogen bulb.
