Your Handy LED Light Buying Guide
Considering replacing your incandescent bulbs and lamps for LED light? Confused about what LED lighting is and why it’s increasingly popular? Our LED Light Buying Guide answers the most commonly asked questions about LED lighting to help you better understand the energy-efficient, environmentally friendly world of LEDs.
What Does LED Stand For?
As an LED light buyer, you probably want to know what LED means. LED is an acronym for Light Emitting Diode, which refers to the LED’s use of a semiconductor (as opposed to a filament found in incandescent bulbs) to produce light. Light is produced by the constant movement of electrons in the semiconductor’s material.
What Are The Benefits of LED Lighting?
The number one benefit of LED lighting is efficiency. LED lights use between 75 and 90 percent less electricity than standard incandescent bulbs, so they are better for the environment and your wallet.
While the upfront cost of LED bulbs or fixtures is higher than for incandescent lighting, upgrading to LED bulbs will save you money in the long run because of their low energy use and remarkable life span. Unlike conventional bulbs that lose most of their energy as heat, LED lights remain cool and don’t waste energy.
In short, here is quick list of benefits an LED light buyer should consider:
How Long Do LED Lights Last?
Generally, LEDs promise a lifespan of anywhere from 25,000 to 50,000 hours, which translates to 10 to 30 years of residential use. This is about 50 times longer than a typical incandescent bulb, which typically only lasts about 1,000 hours. LEDs also outlast CFL bulbs, which average 9,000 hour lifespans.
How Bright Will My LED Light Be?
Brightness is measured in lumens. The more lumens a bulb produces, the more light it emits. It is also important to understand the color temperature and CRI, or color rendering index, of a bulb.
Color temperature is measured in kelvins and determines the warmth or coolness of light. A color temperature of 2700K produces a warmer light, while 3500K produces a cooler, white light. Light sources with a higher CRI make colors appear more crisp and clear.
Are LED Lights Dimmable?
LED lights do have dimming capabilities, but it’s always best to follow the manufacturer’s suggestions and refer to their list of compatible dimmers. Keep in mind LED light dims a bit differently than standard incandescent light. LEDs will dim the brightness, or the lumen output, while incandescent dimmers turn the light darker and warmer while dimmed.
