We all know that some light bulbs are “better” than others, but what features determine which lights shine brighter? There are three different types of light bulbs popularly manufactured right now: incandescents, compact fluorescents (CFLs), and light-emitting diodes (LEDs). Incandescent bulbs are the bulbs that we have all grown up using, but they release 90% of their energy as heat, so the efficiency of the energy conversion from electricity to light is unacceptably low. CFLs have become more and more popular in the past decade or so, mainly because they have a higher energy conversion rate than incandescents—which reduces electricity bills. The problem, however, with CFLs is that they still release 80% of their energy as heat. LEDs, on the other hand, release basically no heat; almost all of the electricity that enters the bulb is converted directly into light energy. This makes LED bulbs the obvious choice in energy efficiency. What drives many homeowners away from buying LED bulbs, however, is their cost. LEDs do cost significantly more than incandescents or CFLs, but what consumers often fail to consider in their plight to save money is the LED’s potential for return. The money that consumers save on their electricity bills after installing LEDs covers the cost of the LEDs so quickly that there is absolutely no reason not to switch to LEDs. Make the logical financial and environmental choice: go LED.
