Lumens vs Candelas
What is a (Lm) Lumen?
A lumen is a unit of standard measurement used to describe how much light is contained in a certain area.
What is a (Cd) candela?
A candela is a measurement of the intensity of light, used in the International Standard (SI) measurement system.
Both are very simple definitions on complex measurement units, but at Ledwave our will is to make understand our customers and flashlight enthusiast with very basic facts why Candelas and why Lumens.
The most concern of all users is to know what is the real reach of the flashlwight or how far the flashlight they carry in their hands can illuminate targets in darkness, we at Ledwave we can give the exact answer of that by using candelas as a unit because it’s the unit that can provide the luminous intensity which is the only “real” way to know what is the reach that a flashlight can carry out.
At Ledwave we provide exact readings over all our program of flashlights for users know the exact candela rating with the correspondent reach of each Ledwave flashlight according to Photometric and Gonophotometric official certified labs (ENAC) of the technical university of Barcelona (Spain).
Why other flashlight manufacturers advertise measurements in Lumens but not candelas?
There might be many reasons for it, but the main is that surprisingly most of flashlight manufacturers don’t even know how to measure the flashlight light output from the flashlights they manufacture and they advertise the reach of the flashlight with the output of light contained in a certain area (lumens), by naked eye and with wrong measurement unit to know the reach.
Many others just lie or invent measurements to sell more flashlights and confuse all users.
At Ledwave we only provide the real measurement of every model manufactured with official government certifications and international certified standards provided by our labs in the University of Barcelona.
