Energy-efficient light bulbs consume less electricity compared to traditional incandescent bulbs, resulting in lower energy bills and reduced environmental impact.

LED bulbs have a significantly longer lifespan (up to 50,000 hours) and consume less energy compared to other types of light bulbs.

Traditional incandescent bulbs typically have a lifespan of around 1,000 hours, while energy-efficient bulbs like LEDs can last up to 50,000 hours.

Bulb shape is not a primary factor to consider when choosing an energy-efficient light bulb. The main factors are wattage, lumens, and color temperature.

Lumens measure the total amount of visible light emitted by a light source.

The color temperature range of 2700K-3000K is commonly used for warm, inviting lighting in residential settings.

Luminous efficacy measures the efficiency of a light bulb in converting electrical energy into visible light.

LED bulbs have excellent color rendering properties, meaning they accurately reproduce the colors of objects under their light.

A 12-watt energy-efficient light bulb typically provides the same amount of light output as a traditional 60-watt incandescent bulb.

The Department of Energy (DOE) sets energy efficiency standards for light bulbs in the United States.

The Energy Star program is a voluntary program that promotes energy-efficient products, including energy-efficient light bulbs.

LED bulbs are known for their dimmable capabilities, allowing users to adjust the brightness of the light.

The typical CRI range for energy-efficient light bulbs is 80-90, indicating good color rendering properties.

Color temperature is not typically considered when choosing an energy-efficient light bulb for outdoor use. The primary factors are wattage, lumens, and motion sensor compatibility.
