Improvements in lamps, ballasts, controls

Improvements in lamps, ballasts, controls, and luminaires bring new options

Manufacturers have rapidly introduced a succession of improved lighting technologies in the past few years, but users have been slow to apply them. New models are announced in rapid order, making product selection confusing and overwhelming. Those users who understand the characteristics and advantages of new products will be able to select models that will produce the greatest cost savings for the investment.

New large screw-base compact fluorescent lamps (CFL) include the following models, which can be used in high-ceiling applications to replace 200-300-watt (W) incandescent lamps. Each model is rated at 65 lumens-per-watt (lm/W).

A new four-pin, rapid-start CFL, rated at 4300 lm (light output equivalent to a 200-W incandescent lamp) is also intended for high-ceiling applications. Electronic ballasts are available, and at least one company offers a matching lamp and ballast system.
