LED's Provide Energy Significant Savings

LEDs: Comparing Apples to Apples
Chuck Ross

Over the years, we’ve become used to describing lamps by how many watts they draw, as with basic Edison lamps, or by the size fixture or ballast in which they’re used, as with fluorescent tubes. 

However, neither of these approaches says anything about the quality of the light those lamps produce, which can cause problems when trying to match expectations to actual lamp performance. 

While terms like “warm white” or “soft light” might have become familiar marketing terms, the lack of quantitative measurements for these qualities can make matching new lamps to well-established expectations difficult. More

Planning for Florescent T12 Lamp Phase Out

More than 500 million T12 fluorescent bulbs are still in use throughout the U.S., but by July 2012, manufacturers will cease producing most of these products. As with many incandescent lamps, the T12 fluorescent – with a design that hasn't changed significantly since 1938 do not meet current energy-efficiency standards.

The first choice is to maintain the existing fixtures and retrofit them with florescent T8 ballasts lamps. Choosing this option will provide environmental and economic benefits since T8 lamps contain less mercury than T12 lamps and offer longer life. Their light output also does not degrade as much over time than less-efficient T12 lamps.

On the surface, a one-for-one T8 retrofit may seem the least expensive approach, however new fixtures designed for T8 technology may provide better light optics a comparable overall cost, especially when energy savings are factored into the equation. Read More
