How did you decide it only puts out 900 lumen? I have a 900 lumen LED flashlight - different manufacturer - and this 1300 lumen LED flashlight. (I need bright flashlights for my work.) This 1300 lumen flashlight is clearly brighter than the 900 lumen flashlight, especially when I'm inside a totally darkened structure. I am happy with both of my lights. Not so much for the 350 lumen one I bought previously for the same reason. It works well and is well-made - it's just not bright enough. These two (900 and 1300) are awesome.

If you're attempting to use a Lux meter to measure Lumens; - Lux is not the same as lumens... - Energisers rating would be a measure of luminous intensity, as expected. - A Lux meter can only measure luminous flux (Lux is shorthand for luminous flux if you haven't caught on) - Lux is measurement of luminous flux, that is Lumens over a given area (ie. square meters). Measuring using a Lux meter, even if you are utilising correct math to approximate 'lumens', will not produce correct results due to an enormous amount of light noise (if you're informed enough to be using correct math, you should already be aware of this), and the inherent limitations of the math approximation. - "Affordable" Lux meters are understandably inaccurate - You simply cannot accurately measure the brightness (whether it be lumens, candela, or Lux, as they're all mathematically related) of a light source accurately outside of a laboratory
