Energy-efficient lighting typically uses less energy to produce the same amount of light as traditional lighting, resulting in reduced energy consumption and lower electricity bills.

LED bulbs have a significantly longer lifespan and higher energy efficiency compared to traditional incandescent bulbs, CFLs, and halogen bulbs.

Energy-efficient lighting achieves energy savings primarily by consuming less electricity while producing the same or even higher levels of illumination.

Leaving lights on unnecessarily wastes energy. Strategies for reducing energy consumption through lighting typically involve using natural light, installing dimmers, and using energy-efficient light bulbs.

Luminous efficacy is a measure of how efficiently a light source converts electrical energy into visible light.

Bulb shape does not directly impact the energy efficiency of a light bulb. The primary factors that affect energy efficiency are bulb type, wattage, and color temperature.

LED bulbs are more energy-efficient than incandescent bulbs, so a 10-watt LED bulb can provide the same amount of light as a 60-watt incandescent bulb.

LED bulbs offer a wide color gamut, allowing them to produce a diverse range of colors.

Color temperature is a measure of the warmth or coolness of light, expressed in degrees Kelvin (K).

Using higher wattage bulbs to compensate for poor lighting design is not an effective energy-saving strategy. Instead, it is recommended to address the underlying lighting design issues.

Dimmers allow for the adjustment of light intensity, which can lead to significant energy savings.

LED bulbs emit very little heat compared to traditional lighting technologies.

CRI (Color Rendering Index) is a measure of how accurately a light source renders colors compared to natural light.

Smart thermostats are not specifically designed for lighting control. Occupancy sensors, daylight harvesting systems, and dimmers are all examples of energy-efficient lighting control systems.

A color temperature of 3500K (neutral white) is generally recommended for task lighting in office environments as it provides a balance between warmth and coolness, reducing eye strain and improving visual comfort.
