Technical FAQs 4
What is lumens & Watts?
The measure of the brightness of a light fixture is lumens, not watts. Lumens are the measurement of visible light energy. The higher the number of lumens, the brighter the light. Lighting fixtures used for illumination are usually labeled with their light output (in lumens), which is legally required in many jurisdictions.
How many watts is a 100 watt LED bulb?
For example: A 60W incandescent bulb is equivalent to a 9W LED. A 100W incandescent bulb is equivalent to an 18W LED. Because LED technology differs from conventional incandescent bulbs, switching to LEDs often raises concerns about wattage. To achieve the same brightness (lumens), LED lights use significantly less energy (watts).
Are Watts a unit of brightness?
Since we have traditionally used incandescent light bulbs, we are accustomed to using watts as a unit of brightness, but this is incorrect. The measure of the brightness of a light fixture is lumens, not watts. Lumens are the measurement of visible light energy. The higher the number of lumens, the brighter the light.
Is a 100W bulb brighter than a 60W bulb?
A 100W bulb was indeed brighter than a 60W bulb. But with LEDs and solar lighting, wattage measures how much power is consumed, not how much light is produced. Two different solar lights might both consume 5 watts, but one could emit 500 lumens while another gives off 800 lumens. The difference? Efficiency.
