An ongoing project in the FamilyTrivium Household has been a conversion from incandescent and fluorescent to LED lighting. On this blog, we’ve already examined the first two and, in this post, we now turn our attention to the last.
We turn, once more, to the Learning section over at Bulbs.com to find that “LED” stands for “light-emitting diode.” LED is a solid-state technology where a solid material encapsulates the materials used to generate light. This means that the technology is less affected by shock and vibration, than incandescent and fluorescent counterparts, and should have a longer service life.
The first visible-spectrum LED was developed by Nick Holonyak, Jr. in 1962 according to Bulbs.com. At the time, Holonyak was consulting for GE and each LED cost approximately $200 to produce. Additional, early LEDs were only able to output red light and were quite limited in their output. In other words, their utility was limited to applications such as indicator lamps. Only more recently have LEDs evolved to area lighting usage.
In our house, we’ve reached the point the point where LED bulbs are in use in the areas where we spend the most time: living room, kitchen, bedrooms. We do still have some CFLs and an incandescent or two being used in our bathrooms, garage and basement. The LEDs that we have put into service put out a nice natural color of lighting reminiscent of the old soft white 40 or 60 watt incandescent bulbs while only consuming 5-10 watts. As an added bonus, compared to fluorescent bulbs, they turn on right away and reach full brightness immediately, and without the mercury content.
