I’ve been searching for some LED lamps to test since I have been less than impressed by the very short lifetime of Compact Fluorescent Lamps (CFLs). The CFLs do not last anywhere near the claimed 5,000, 8,000, or 10,000 hours. I think they might last that long if I turned them on and never turned them off, but that is not exactly my home lifestyle. So, I’ve been watching and waiting for some Suitable LED lamps to test. That day arrived when my wife said she was sick and tired of those CFLs in the kitchen that took 30+ seconds to get bright first thing in the morning. The problem was bad enough that I had switched one CFL back to an incandescent bulb months ago. When you want/need light you pretty much need it now. So I went to LEDtronics.com and bought a couple of R30 and PAR30 lamps.
I bought two completely different styles. One used five high power dimmable LEDs with a narrower 25 degree beam width and a 3000K color temperature. The other uses many lower power LEDs to produce a 5500K beam with a width of 40 degrees and could not to be used with a dimmer. I planned to use the latter in the kitchen where the distance between the lamp and the counter top was about 5′. The high power lamps are going in the ceiling of my family room 16′ above the floor. I selected the specific lamps based on their total lumen of output and their candle rating (includes the effect of varying beam width). My goal was to select a lamp that appeared to result in the same candle rating of the incandescent lamps I was replacing.
LED lamps are very intense, but not all that bright. These lamps in particular have clear lenses and produce a very direct light. The 40 degree spots did not work in the kitchen. We wanted a more diffuse light there. They do, however, work very well in the bedroom and the bath over the spa where they provide a delightful ambiance. Before I installed the high power spots in the ceiling fixtures I ran a quick test by putting them in a work light fixture. They produced a nice bright spot that was easily visible during the brightest part of the day on a wall 25′ away. I have since installed them and am very happy with the intensity of the light when I’m sitting at the computer underneath one of them and very pleased with way the light looks from across the room. It gives the room a completely different look. I’m planning to get two more for the other pair of corners in the family room.
I have to give these a thumbs up so long as they last their predicted lifetimes. The nature of the illumination is quite different from either incandescent or CFLs, so you should not expect that they will perform exactly the same way. In the right situation they perform better. In the wrong one, they can be worse. Given their current cost it will be an expensive experiment.
