Frequently Asked Questions
Yes, dimming an LED bulb significantly reduces its energy consumption. Most modern LEDs are designed to be dimmable and save power at lower brightness levels.
While LEDs are very efficient, hidden costs can include the initial higher purchase price (accounted for in this calculator), and sometimes the need for compatible dimmer switches.
Color temperature (measured in Kelvin, e.g., 2700K warm white, 5000K daylight) refers to the shade of white light a bulb emits and does not directly impact its energy efficiency or wattage.
In most cases, yes, as LEDs are available in standard screw-in bases. However, ensure the LED’s wattage equivalent matches the incandescent you’re replacing, and check if existing dimmer switches are compatible with LEDs.
A: Lumen (lm) is a measure of brightness, indicating how much light a bulb emits. Wattage (W) measures energy consumption. For energy efficiency, compare lumens per watt: higher lumens for lower wattage means more efficient lighting.
Yes, CFLs contain small amounts of mercury, which is a neurotoxin. This is why they should be disposed of properly at recycling centers. LEDs do not contain mercury.
Further steps include turning off lights when not in use, utilizing natural daylight, using occupancy sensors or smart home controls, and choosing appropriate light levels for tasks.
