Ballasts detect end of life
Electronic ballasts include end of life detection circuitry. Units are for 120 or 277-V operation of 36/39-W, 40-W, and 50-W long twin tube, and 55-W FT55/DL/RS lamps.

A special circuit removes power from the lamp when it senses a failure, preventing overheating of cathodes and minimizing the possibility of melting and cracking.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
