HID pulse-start ballast family has been expanded to include 750- and 1,000-watt metal-halide ballast retrofit kits available in quad tap for 120, 208, 240 and 277 volts and in tri tap for 120, 277 and 347 volts. Kits contain the appropriate core and coil, a properly rated and prewired capacitor-and ignitor, if required-color-coded leads, installation instructions and trouble-shooting tips.
For 10 years I've subscribed to several magazines in the same genre as yours. "The People Problem: Labor Solutions" (April, 2000) is the first article I've seen that addresses the older engineer.I retired from a position as manager of engineering at 66. I quickly found that hobbies are boring if they are the only reason for getting up in the morning.
Pipe-joining system for small-diameter, lightwall stainless-steel and carbon-steel piping in sizes 0.5 inch through 2 inches requires no welding, threading or flanges. Assembly involves cutting the pipe to size, inserting into couplings and pressing with a handheld electric or electrohydraulic tool, creating a permanent mechanical union.
Industrial lighting fixture offers optimal performance with T8 lamps and high-light-output ballasts. Precise herringbone slots run the length of the fixture body to provide 170 degrees of even distribution above the fixture at 92-percent energy efficiency and 90-percent light output below the fixture.
In the course of renovating its Bloomfield, Conn., service center, Otis Elevator received a $27,000 incentive from Connecticut Light & Power Company and is expected to save more than $16,000 in annual energy costs by switching from traditional metal-halide lamps to a more energy-efficient, pulse-start technology.
Security-lighting wallpack is a low-wattage model designed to reduce glare, sky glow and "light trespass" at entryways, walkways and general perimeter areas. Wallpack cuts light off sharply, eliminating wasteful light above 90 degrees. Device also prevents perimeter light from spilling onto adjacent properties.
LCD-based lighting control offers direct access to manufacturer's lighting systems without the need for personal computers, laptops or other plug-in devices. The control, with a new large-button design, is factory programmed to be fully functional right out of the box. Users can monitor and operate lighting in any room of a facility from one or more locations.
