For instance, if the light gives more of a blue color, it would have a “cool” temperature, and if it’s more yellow looking, it would be “warm” in temperature. Color TemperatureĬolor Temperature is the shade of color that characterizes the how the white light looks. It’s a win-win if you know what you’re looking for when you’re at the store. They can be dimmed and the big benefit is that they produce the same amount of power as the incandescent blubs but use much less energy to do so. LED lights are far more sophisticated than incandescent bulbs, as different types can let off a different shade or color or white light. The other, known as RGB conversion, is when red, green and blue light is mixed, resulting in white light. One is phosphorous conversion, where phosphorous is put onto the diode to it can make white light. To make the light white so we can have normal looking lights on our homes, they use two methods. Naturally, the LED is not a white light source, which is why they are they are commonly used for things like street lights, colored holiday lights and digital billboards. Instead, they use chemical compounds to produce more efficient light. Unlike traditional lighting, the LED does not require the heating of a filament to light up. Let’s explore! The Light-Emitting Diodeįirst thing’s first: the Light-Emitting Diode – Simply put, like any other light, the LED is a semiconductor device that emits light when an energy current passes through it. These can be hard to understand, but without knowing them, it can make it hard for the common consumer to choose the perfect light for the home. As I’m sure you’re aware of, there are still many technical terms about them that would be helpful to know when shopping around. Have you seen our cool videos (links are in the next sentence)? We have already debunked the myths and given you some visual comparisons about the LED bulbs. We hear people telling us they’re important to use, but are hesitant to actually buy them because of the price, type, and all of the terminology that comes with it. We’ve all heard of them, but do we actually know how LED light bulbs are different from other bulbs (such as the traditional incandescent light bulb)? The term “LED” has been getting more and more buzz as we try to move towards a lifestyle of conserving and saving energy. Any defective LED bulb will usually fail within this time.Ahh, the Light-Emitting Diode…otherwise commonly known as the LED. Most LEDs come with a minimum 2-year guarantee.Incandescent bulbs and CFL bulbs are more easily broken than LEDs, which increases their cost of use. Bulb breakage and bulb replacement costs have not been factored into this comparison chart.Some manufacturers claim the new LED bulbs will last up to 25 years under normal household use, but this is not proven.

Estimates of bulb lifespan are projected, since it would take about 6 years of continuous lighting to test.

We used the figure of $5.00 (for a 60 watt equivalent LED bulb) as an average among lighting retailers.

Residential energy costs among the various states range from 35.17 cents (Hawaii) to 11.4 cents (Washington) per KWh. The figures used above are for comparison only, and are not exact.
