LED FAQ Common Questions | LED Lighting Guide


Ever since Thomas Edison introduced the incandescent light bulb to the world, we’ve been using it ever since. Today, however, there are many more options when it comes to lighting our homes and businesses.

Modern light bulb choices give you the light you want while saving you energy and money. LEDs are the latest lighting innovation to light up our homes and businesses. Instead of using a filament or glass bulb, LEDs use tiny solid-state chips, similar to the ones found in computing devices. The chips efficiently convert electricity into light by a process known as electroluminescence.

Home lighting accounts for around 10% of your total energy bill. By changing around 15 light bulbs to energy-efficient LEDs, you can save over $50 a year on electricity costs.

Use only the most energy-efficient LEDs and your savings go up. 

What does LED stand for?

LED stands for light-emitting diode.

What are LEDs?

LEDs are a type of solid-state lighting, which uses semiconductors to convert electricity into light. LEDs use around 20% of the energy of traditional incandescents and last up to 25 times longer. Compared with halogen incandescents, LEDs use around 25% of the energy and last around 8-25 times as long.

Where can I use LEDs?

LED lights can be used in nearly any area of the home. They are used for all different kinds of bulb types, including decorative, Christmas, undercabinet, recessed, PAR reflectors, A-shape, MR reflectors, and much more. They can be used to replace 40W, 60W, and 75W light bulbs.

LEDs work well in both indoor and outdoor environments since they are durable and can perform well in both hot and cold environments. When installing outdoor lights, such as pathway lights, step lights, porch lights, and Christmas lights, look for LED products. Also consider using solar-powered outdoor lighting, especially if you live in an area that receives a lot of sunlight.

As LED technology improves, the list of practical applications grows every year. Due to the high efficiency and directional nature of LEDs, they are ideal for a wide variety of residential and industrial uses.

Should I switch to LED lighting?

LEDs are known for having longer lifespans, better energy efficiency, and producing less heat than traditional lighting. They are resistant to vibrations and shocks, and can function effectively in extreme heat and cold.

Here is a quick list of the benefits:

· Longer Lifespans – lasts up to 100,000 hours/20 years, around 50x longer than traditional incandescents.

· More Energy Efficient – uses less than 1/6 the amount of energy compared with incandescents and halogens.

· Lower Maintenance Costs – longer lifespans and enhanced durability translates to less time and money replacing and maintaining lights.

· Safer to Use – LEDs don’t heat up, contain mercury or emit harmful UV or IR radiation, making them safe to use around people, art, and flammable objects.

· More Durable – since LEDs are made of plastic and don’t use filaments or glass bulbs, they ast longer an are much harder to break.

· Easier to Use – due to their higher efficiency, you can easily string multiple LED strings together without overloading the circuit. If one bulb burns out, the others stay lit.

Why are LEDs more expensive that other bulbs? 

LEDs are more expensive to buy because they are more expensive to make. The trade-off is that they save money over the long-term by reducing energy, maintenance, and replacement costs. As technology improves, prices are expected to drop.

What makes LEDs different from other bulb choices?

LED lighting is different from other lighting choices in a variety of ways:

· Light source – LEDs are very small, about the size of a dot, and come in a variety of colors, including a mix of red, green, blue, white, and color-changing LEDs.

· Direction – LEDs emit light in a specific direction, eliminating the need for reflectors and diffusers which are used to trap light. Instead of having to reflect the light to a desired direction and losing energy and light in the process, LEDs make it easy to direct the light where you want it. For this reason, LEDs are highly recommended for recessed downlighting, uplighting, and task lighting.

We recommend replacing nearly all of your bulbs with LEDs, including outdoor lighting, security lighting, Christmas/holiday lighting, recessed fixtures, track lights, lamps, and under cabinet lights.

There is a wide variety of colors to choose from, including dimmable, daylight, and motion sensors. LEDs work well in nearly every area and fixture of your home.

What’s the difference between a cheap LED light ($5-$10) and a more expensive LED bulb ($40-$60)?

Just like other electronics, such as TVs, there is a difference between the cheaper and more expensive versions. For the best light quality and energy efficiency, you will want to buy the more expensive LED products.

The Color Rendering Index measures light quality on a sale from 1-100. Look for a CRI rating of 90 or above.

Will an LED replacement produce enough light to replace my old bulb?

LED lights are very similar to other light bulb’s light output. However, it’s a good idea to visit a lighting store to see exactly how the LED light bulb lights up a space.

LED lights can now effectively replace incandescent up to 100 watts.

How energy efficient are LEDs?

LEDs are the most energy efficient lighting choice available. Light bulb efficiency is measured by the amount of light output (lumens) per unit of power (watt), or lumens per watt. According to a 2014 report by the U.S. Energy Information Administration (part of the Department of Energy), “by 2020, EIA projects LEDs to produce more than 150 lumens per Watt.”

For comparison, traditional incandescents produce around 13-18 lumens per watt. Currently, LEDs produce around 83-100 lumens per watt, still the best efficiency you can get from a light bulb. LED technology continues to make great strides in energy efficiency, as well as improved color temperature and quality.

Keep in mind that the LED bulb is not the only thing that determines its energy efficiency. The bulb works in conjunction with the light fixture. The amount of electricity consumed depends on both the LED device and the light fixture design. A poorly designed light fixture will compromise even the most efficient LED device.

It’s one reason why it is so important to hire professional electricians to design and install your indoor and outdoor lighting. LED efficiency varies by device. Look for the ENERGY STAR® label for the most efficient LED devices. As of this year, there are LED devices available that exceed 100 lumens per watt.

What should I look for when buying LEDs?

Always look for the Underwriters Laboratory (UL) listing for lights that have been tested by an independent testing laboratory.

If you are using your LED lights outside, make sure they are rated for outdoor use.

Enjoy the Benefits of Outdoor LED Lighting

Lighting designers and architects prefer LEDs for outdoor lighting applications. They are able to provide arm white light without sacrificing any lumen output.

Minimize your energy consumption while improving your light quality by calling The Perfect Light for outdoor LED lighting, including Christmas and Event Lighting.

LED holiday lights come in a wide variety of colors and styles, including twinkle lights, rope lights, icicles, and globe lights.
