The exact energy saving depends on the season, because the lights are on more in the winter when days are shorter. However, there are other areas where energy is saved. “The LED bulbs do not emit as much heat as the old incandescent bulbs did. Of course, that means the air-conditioning does not need to come on as much to cool the ambient air.”
The outdoor lighting was converted first, and once this was done, Deane’s electric bill went down by approximately $20 per month.
“I did all the yard and tree lighting front and rear, then added PAR38 downlights under the eaves. I then did the indoor lighting, first removing any fluorescent tube lighting,” he says.
The garage—from which Deane runs Wired Communications, his internet business—had six double light "shop" lights which were gobbling up over 560 watts. “I now only use approx. 60 watts doing the whole garage with 20 PAR20 lamps on track lighting. Also, the garage is air-conditioning and well insulated, there are also savings from not having those HOT tubes and ballasts!”
“For some cabinet locations I used the ‘festoon’ type LED bulbs as the fixtures were already there. Those bulbs used to get so HOT that I received a second-degree burn from them before I switched them out.”
Deane says he has had a good response to the new lighting. “Folks that come over love the ‘cool’ white look of my interior lighting. At first they would say, "No, I would not want that", or "My wife only wants that warm-white look of the old incandescent." But, once they have been over a few times at nighttime, the comments are more positive.”
