What are the benefits of replacing bulbs with LEDs?

LED bulbs are 90% more efficient than traditional light bulbs. They also have an extremely long lifespan and produce very little heat.

Where can I use LED bulbs?

LED lights are very versatile and can be used almost anywhere a traditional bulb has been used.

How is quality rated for LED lights?

The Color Rendering Index (CRI) is used to measure light quality on a scale ranging from 1-100. Many LED bulbs are rated at 80 and above, while some are even rated at 90 and above.

How long do LED bulbs last?

The great thing about LED lights is that they never technically "burn out". Instead, they simply get dimmer over a period of time (also called lumen depreciation).

Can LEDs be used with dimmers?

Yes, certain LEDs are listed as being dimmable compatible.

What effects do LED bulbs have on the environment?

LEDs help the environment by creating the same light output as their counterparts while using significantly less electricity. This results in lower emissions from power plants.

Are LED bulbs cost effective?

Compared to when LEDs first came onto the market, the prices have gone down tremendously. Costs between models vary, but a high-quality bulb will be more expensive than your typical lightbulb.

How much money can I save by switching to LED?

Switching to LED will save the average household $278 per light bulb over the course of 23 years.
