And the opposite can also be true: A flashlight can have a very modest output in lumens and yet can be remarkably effective in lighting up an object very far away.It sounds like you may be using the incorrect replacement lamp for your flashlight.
The lens is adjustable making the flashlight versatile.
It starts with answering a preliminary question, which is, “How do you define when the useful life of an LED is at an end?” With an incandescent (filament) lamp, this question is so easy that nobody even asks it: The life of an incandescent lamp is over when it burns out. 99.

The above battery manufacturer contact information, current as of late September 2016, is provided to you as a courtesy but is, of course, subject to change by the battery manufacturer.That said, the flashlights will operate with NiMH rechargeables, and use of NiMH rechargeables will not harm the circuitry nor otherwise damage the flashlights in any way.
If leak damage does occur, it is sometimes difficult or impossible to get the batteries out of the barrel to see what brand they are. And, for example, if an LED were driven grossly in excess of its design-rated voltage and/or current, it could fail quickly. A flashlight can have a very high Light Output (measured in lumens), and yet have a very short Beam Distance (measured in meters). D & C Cell Mag-Lite® flashlights have different numbers of batteries or cells and therefore operate at different voltages, so each size Maglite® flashlight needs its own unique lamp size. We do this because the designs of these flashlights are optimized for use with (non-rechargeable) alkaline batteries.

Also, the discharge curves of NiMH batteries typically differ from those of alkaline batteries – so the two battery types may behave differently under load.No. Add to list . 2 Reviews. When this happens (and there is no evidence of barrel crushing or denting), the cause likely is that a battery leaked and produced corrosion that involved the tailcap threads, seizing of the tailcap onto the flashlight’s barrel.In any of these situations, the likely cause is alkaline battery leak damage.Customer Service 1-800-891-6091 or 1-800-237-7000So while a flashlight’s Light Output – its “lumen rating” – tells you nothing at all about how good or bad a job the flashlight does at forming a useful beam of light, the flashlight’s “Beam Distance” rating is all about its ability to form light into a useful beam and send it in a useful direction.
A quarter of a lux can roughly be described as the light level provided by a full moon in an open field on a clear night.
