Convert electrical power to luminous intensity with ease using our Watts to Candlepower Calculator for efficient lighting design.
4 Μαρ 2024 · Efficiently convert watts to candlepower with our reliable calculator, simplifying lighting design and energy management.
15 Οκτ 2024 · The Candlepower ↔ Lumens Calculator is a useful tool for understanding and converting between two critical measurements of light: candlepower and lumens. Candlepower measures the luminous intensity of a light source in a specific direction, typically in candelas.
When converting from halogen bulb to LED there are often multiple eligible cross-reference bulbs. Many bulbs will use the same base and connectors while the different model numbers will be determined by color and wattage.
Multiply the total wattage by the performance factor (lumens per watt). Divide the result by 12.57 to obtain the candlepower in candelas. What is Candlepower? Candlepower, also known as luminous intensity, is a measure of light intensity in a specific direction, typically measured in candelas (cd).
So, if you previously bought incandescent bulbs measured in watts, here's a handy guide showing how many lumens you might need and the wattage conversion. Note that these conversions use a set average figure for lumens per watt (lm/W), based upon data from the Energy Saving Trust and Energy Star.
Depending on the bulb and the manufacturer, LED technology typically produces 75-110 lumens/watt. So, LEDs are generally about 7 times more efficient at producing light than incandescent bulbs. Use a 7:1 ratio as a rough guide when selecting an LED bulb to replace an incandescent bulb.
