Maglite uses step-down regulation, which reduces the Pro 2D’s output to 60% during the first 12 minutes of continuous operation. When used with two NiMH AA batteries (in D-cell adapters), runtime is reduced but performance is roughly the same for the first 2h 30min. Maglite released an LED version of the MagCharger. Features a 680 lumen output and spot-to-flood beam with a quarter turn of the head. Claimed 4 hrs of battery life on a full charge at full power. Other specs are as the Incandescent Version. [4]

Furthermore, D-Cell batteries, being larger than, say, AA batteries, contain far more chemical energy. They can drive bigger loads than a AA, or the same smaller load for a longer time. Comparing the product data sheets of a Duracell D to a Duracell AA ( http://ww2.duracell.com/en-US/Global-Technical-Content-Library/Product-Data-Sheets.jspx?icn=Prim/PrimNav/Product-Data-Sheets&cc=Primary ), you can expect that a D Cell will last 5 times longer than a AA for the same load. (Compare the 250 milli-watt constant-power performance plots.) Furthermore, D-Cells only cost about 3 times as much money, so they are actually more cost-effective than their AA counter-parts. For these reasons, I was considering a flashlight using old-fogey D-Cell batteries, but sporting new-fangled LEDs and electronics. D and C battery models are put on the market; targeted to the public safety and industrial sectors (the 5C, 6C, 7C and 7D models are out of production)

The Maglite Pro LED is only offered with a single battery configuration, which is the compact 2D-cell version. With electronic circuitry and LEDs making large D-cell lights obsolete, this product line simplification doesn’t really surprise us (the only difference between the Maglite LED 2D-cell and 3D-cell lights is runtime). Given my needs, can you suggest a better flashlight for me? (I’m trying to keep it under 50-ish dollars.) Thanks! As we have already seen with the Mini Maglite Pro and Pro+, classic simplicity and modern power define the Maglite Pro series. In this review, we’ll be taking a look at the full-sized member of this family, the single-output Maglite Pro 2D LED. Using two D-cell alkaline batteries, which is the only battery configuration offered, the Pro 2D LED has a maximum output of 274 lumens and intensity of over 33,000 candela. The V4 was released with a newly developed electronic switch enabling a Multi Mode operation and a slightly more powerful bulb producing an output of 245 Lumens. Of course, using D-cells isn’t specifically a problem with the Maglite Pro 2D, but it is definitely a factor to consider. There are many advantages of a larger-sized light, such as being easier to grip, but large lights don’t necessarily have to be heavy. For most of our testing with the Pro 2D, we used Sanyo Eneloop AA’s in plastic battery adapters, and when used with adapters that take two AA’s in parallel, battery weight is halved and runtime is still more than sufficient. If you are considering a full-sized flashlight, we would definitely recommend purchasing a couple adapters to have the option of using AA’s.

On March 30, 2007, the Los Angeles Police Department announced that they would be switching to a smaller, lighter LED flashlight that cannot be used as a baton, in response to a highly publicized incident where an officer was accused of using excessive force against a suspect by using a Maglite.

If you want a dependable emergency solution, my recommendation would be to choose a light that can take lithium primary batteries (like the Energizer Ultimate Lithium). You could get a Mini Maglite Pro/Pro+, or use AA adapters in the Pro 2D. Lithium batteries are leak-free, perform well at temperature extremes, and perform much better than alkalines.

Powered by two D cell alkaline batteries, this fine instrument has a run-time of 6 hours, 30 minutes on high, and a beam that reaches up to 323 metres range. The torch will always come preset in function set #1 (general). To change to a different function set simply unscrew the tail cap until the torch no longer turns on, pause for two seconds and then hold down the switch. While still holding down the switch, tighten the tail cap until fully tight and the torch will start to blink after four seconds, the number of blinks indicates the function set. To select the desired set, wait until the torch has done the required amount of blinks (e.g. four blinks for function set #4 Tactical), and then release the switch. Customer service people were nice but I don’t need an explanation as to why it does that. Don’t waste your money on the 2D led with voltage reg. It doesn’t work and other people are telling you it doesn’t work. The light isn’t a total waste though, I understand you can cut the aluminum tube right behind the switch, drill and tap the end cap to 1/2×28, and make a suppressor out of it. Or, you can punch out the lens and guts out of it and make a decent funnel. Comparing the 250mW charts is not representative of the load presented by a high-output flashlight. For the Pro 2D, you can expect about 3W of power (it’s a very rough estimate, but sufficient to illustrate the point), which means that each battery needs to deliver 1.5W. Take a look and see if they have charts for 1.5W constant power or 1.5A constant current. Alkaline batteries perform poorly with high current/power draw, so you may not even be able to find a chart for the AA.
