How To Choose The Best LED Light Bulbs


We must be not feel unfamiliar with LEDs, LED technology has been greatly changed our lives. Various products which related close to our lives are using LED technology, such as LED car lights, LED watch, LED Shirts, LED screen, LED Light Bulbs etc. When we are shopping, we are trend to choose LED items, because we can get many benefits from LEDs. Through there is a little expensive on LED products, but just for our earth environment, we have no excuse to refuse these LEDs. LEDs are actually semiconductors that produce light more efficiently than traditional light sources. When electricity is passed through them, they emit energy in the form of light. LED Light Bulbs can be up to 90% more efficient than traditional household filament light bulbs. There are a growing number of LED light bulbs on the market today. How to choose the best one? Let’s discuss some purchasing considerations for the first-time buyers.

LED Light Bulbs

1. While the initial cost per bulb is still high, the total lifetime cost of an LED light bulb is actually lower than that of equivalent incandescent and CFL bulbs. Taking into consideration energy costs as well as time and resources required to replace incandescent and CFL bulbs, an LED bulb that lasts 80,000 hours has a much lower lifetime cost.

2. While LED light bulbs do last much longer than conventional bulbs, look closely at manufacturer claims for bulb life. The life-span of an LED light bulb should be its “half-life.” LED light bulbs do not burn out; rather, they gradually fade out. When a vendor says an LED bulb will last 80,000 hours, they mean that at that point, the chips will have reached 50% efficiency, and the bulb ought to be replaced. So, the bulb might last 100,000 hours or more, but its efficiency will have degraded greatly by that point. Using this 100,000-hour life as a selling point is therefore misleading. While LEDs don’t last forever, they will last 50-75 times longer than a comparable incandescent and 6-8 times longer than a CFL.

3. When comparing LED light bulbs, you need to understand lumens. The lumen is a standard unit you can use to compare LED light bulbs to standard bulbs, such as incandescents and halogens. Roughly, a lumen is a measure of brightness. Lumen quantity is important, but maybe more important is lumen quality, i.e., luminous efficacy (lumen/Watt). Today’s quality LEDs have a luminous efficacy between 60-70 lumens/watt.

4. Color temperature and beam spread are the other key tools for comparing LED lights. Both color temperature and beam spread are measured in degrees. Color temperature refers to the color of the light emitted. In general, 3000 Kelvin is warm white (closer to infrared light) and 5000 Kelvin is cool white (closer to ultraviolet light). Cool white is brighter because it is the natural color of LED light, whereas chips that emit a warm white light require a phosphorous “filter” to “warm” the color temperature, thus reducing the chip’s brightness. Beam spread is the angle of the light that is being emitted. The lower the number, the more like a “spot” the light is.

Because of their many advantages over traditional incandescent and fluorescent light bulbs, LED Light Bulbs will become the most popular bulbs in future. LED light bulbs solve a multitude of economic and environmental problems that have plagued and continue to plague users of other types of lamps.
