What to consider when choosing a lightApril 29, 2019
IT’S ALL ABOUT THE LUMENS
There seems to be some confusion these days about how to measure the brightness of a bulb. It was relatively simple when we all used incandescent lights. You could choose from a 40, 60, 75 or 100 watt bulb, and we all have a rough idea how bright that will be. With the introduction of CFL and LED technology, this now has got a little bit more complicated.
Nowadays it’s all about the lumens!
A lumen is a standard unit of light as it is perceived to the human eye. Essentially it will tell you how bright something is, unlike a watt, which is actually a measurement of energy consumption or output. The lighting industry has standardised ways that it measures the total emission of light from a product and this information is now included on most product packaging.
|Bulb Type||Bulb Efficiency (Lumens per Watt)|
|Standard Incandescent Lamp||Approx. 15 Lumens|
|Halogen Lamp||Approx. 25 Lumens|
|Compact Fluorescent Lamp (CFL)||Approx. 50 Lumens|
|LED Lamp||Approx. 80 Lumens|
