Question 1

Why does my flashlight only stay on for five seconds then turns off.  I've tried replacing the batteries several times.

Accepted Answer

If it only stays on for 5 seconds after you press the on switch and then lift your finger off the switch, your flashlight is defective. This series is programmable but does not a 5-second setting. Hopefully it is still under warranty so you can get it repaired or replaced.

Question 2

It's advertised as "Up to 524 Lumens (3-Cell D)." So what are the max lumens on this 2-Cell D unit?

Accepted Answer

Going by the Packaging material, the two D cell also puts out 524 Lumens. I tend to agree with this as this flash light is as bright as my much larger Dorcey rechargeable portable spotlight.

Question 3

Does this light have a memory mode where it can be set to a mode you want and not have to cycle every time you turn on?

Accepted Answer

No it doesn't. There are 4 or 5 different programmable lighting profiles that may have the desired mode you want for the first button on.
Your MAGLITE® LED 3rd GEN flashlight is capable of five different functions – Full Power, Low Power, Strobe (flashes 12 times per second), Eco and Momentary On/Off (stays on only while the switch button is held down). Not all of these functions are equally important to every user. That is why these functions are organized into four different function sets – so that you can personalize your flashlight to suit your needs, configuring it for quickest access to the functions that best match your preference.
How To Choose A Function Within a Set
The available function sets, and the functions within each one, are shown in the following table:
As it comes out of the package, your MAGLITE® LED 3rd GEN flashlight is set to the “Standard” function set (Function Set #1 in the chart). If you require only those three functions (Full Power, Low Power and Eco), then you never have to change it. You can select a function within that set by the “Quick Click” method: Turn the flashlight on with one Quick Click and it is on at Full Power.
Turn it off, then turn it on with two Quick Clicks (about as fast as you would say “Click Click”) and it
turns on at – the Low Power function. Turn it off, then turn it on with three Quick Clicks (about as fast as you would say “Click Click Click”) and you have the Eco function.
Selecting a function within any of the other function sets works the same way –with one, two or three Quick Clicks, as the chart shows. For example, if you are in Function Set #2 and you want to select the Strobe function, begin with the flashlight off, apply three Quick Clicks, and your flashlight will strobe.
How To Go From One Function Set To Another
Your MAGLITE® LED 3rd GEN flashlight’s “standard” setting is Function Set #1. If you want to keep that setting you don’t have to do anything. Function Set #1 will always be in effect unless it is changed. If you want to choose a different function set, follow these steps:
1. Unscrew the tail cap (you may not have to remove it all the way;
you only need to back it out of the barrel enough that the flashlight will not turn on).
2. Pause for 2 seconds.
3. Press the switch button and keep holding it down.
4. While still holding down the switch button, screw the tail cap back in until it is tight.
5. Keep holding down the switch button. Within about 4 seconds the flashlight will start to blink.
6. The number of blinks indicates the new selected Function Set.
7. To choose a new Function Set, release the switch button after the corresponding number of blinks (releasing after 1 blink chooses Function Set #1; releasing after 2 blinks chooses Function Set #2; release after 3 blinks for Function Set #3, and release after 4 blinks to choose Function Set #4.)
Your choice of a Function Set remains in effect until you change it by repeating the above process.
