LED’s versus CFL’s

If you are considering a renovation, lighting can make a huge different in how a space is perceived. Since energy efficiency is a given, thanks to the Star Energy certificate in pretty much any available product, the key to redesign should be based on the level of illumination.

LED’s (Light Emitting Diodes) as a source of illumination for residential and commercial projects, have come to all facets of lighting. Fluorescent sources have a much more limited lamp life than LEDs, have little flexibility, and don’t work well in cold temperatures. One product first introduced for residential projects in 2010, the versatile Progress Lighting Step Lights, performs indoor and outdoor even in extreme weather.

Panel lighting and fixtures that are enclosed around the lamp, like the reflectors commonly used in recessed lighting, provide an excellent source for ambient and task lighting. One advantage to retrofitted LEDs, is the spread beam of directed light, versus a relative broad beam spread by fluorescents. Additionally, LEDs equivalent lumen efficacy (Lumen/watt) make them a great choice for recessed fixtures.

Optionally, CFL’s light output, long life, color variety, and energy efficiency make them well worth considering on any project, since they can be incorporated into wall sconces, pendants, and wall-wash luminaries. The many alluring “peachy hues” or colors available in fluorescent, work well in the home, although they are not the best at color rendering, provided that you need a higher UV rendition to be used in the work space, for improved visual acuity and accuracy.

When it comes to efficacy (the ratio of the lumens emitted by a light source to the electrical power supplied, lumens/W), lifespan, and the ability to show colors accurately or color rendering, LED bulbs continue to present a unique and rapid pace in development for general lighting applications.
