If the DEWALT Flashlight package shows twice the lumens as a competitor, does that mean it is twice as bright?
LUMENS is a measurement of light output generated in all directions. Although a higher LUMENS output number is a good indicator of brightness, it is only one standard used to measure light. It is important to read manufacturer claims carefully. Savvy shoppers will look for confirmation that complicated tests like LUMENS measurements have been conducted by independent, third party, laboratories. In 2009 the first uniform standards governing the packaging claims of flashlight manufacturers will be implemented. Until then, it is important when comparing flashlight brightness to examine the methods of testing and stated claims very carefully. All DEWALT flashlights are tested by an independent laboratory for the most precise measurement available.
