DieHard’s 6AA Extreme LED flashlight is incredibly bright, very solid-feeling, and has user-friendly controls.
How bright? It lights up the room with 619 lumens on the high setting, 173 lumens at low. It’s kind of funny even calling 173 lumens low. My Fenix LD20 ($50 via Amazon) only outputs 180 lumens in its turbo mode.
Lumens is a measurement of light output, and is often be used to compare flashlights to each other. If you’re not sure how bright 619 lumens is, it might help to instead compare flashlights in terms of throw distance. Just remember that throw distance is based on reflector and emitter design, as well as light output. According to DieHard, the flashlight’s beam can illuminate objects over 1000 feet away.
The emitter and reflector designs give the flashlight a bullseye-type beam profile, with a very tight hot spot focused at the center. This is also how it can provide a 1000-foot reach.
A quick unscientific test, that involved shining the flashlight on a white ceiling from a distance of 4-feet, shows that the tight spot light is about 4″ wide with a 10″ halo around it, and with a flood beam about 50″ across. I didn’t take a measuring tape to the ceiling; these are approximate eyeball measurements just to give you a sense of the ratios.
The flashlight housing is made from anodized aluminum, and the lens is tough polycarbonate plastic. O-ring seals help give the flashlight an IPX4 dust and water resistance rating (what’s this?). This means that the flashlight can handle splashing water without issue.
Pressing the rubberized power button once turns on the flashlight in high mode. Pressing it a second time switches it to low mode. A third press turns it off.
ANSI/NEMA FL1 Specs:
Mode 1 (high): 619 lumens, 5-1/2 hours runtime, 363 meter (1190 ft) illumination range
Mode 2 (Low): 173 lumens, 25 hours runtime, 197 meter (646 ft) illumination range
The flashlight is powered by 6AA batteries, and comes included with DieHard alkaline cells. You can remove the lanyard ring if you wish, but I found it to be quite unobtrusive. It rotates freely around the flashlight housing.
- Very high illumination
- Tough housing, seems durable and well constructed
- Very good quality anodizing
- Free-swivelling lanyard ring doesn’t tug
- AA batteries are easy to find
- Decent runtime
- Comfortable to hold and use, perfect handle size
- Doesn’t get hot with use
- I would prefer for the flashlight to start on the low setting
- Center spot appears “warm”
- Crenellated bezel – why?!
- Polycarbonate lens feels thin and flexes a little (but seems to be very impact-resistant)
Overall, I like this flashlight, despite it not being well suited for my typical usage habits. DieHard describes it as extreme, and it is. It’s extremely bright, and I feel that the housing is extremely durable and solid-feeling.
The beam is a bit too focused at the center for my particular needs, but this helps the illumination carry over medium and long distances. This flashlight is really meant for reach and brightness, with even the low setting a bit too bright for closeup illumination.
What I really liked was the quality of the anodized aluminum housing. A lot of flashlight makers these days boast about their aircraft aluminum alloys and anodized finished, but that doesn’t ensure a quality housing. DieHard did everything right with this design. Although I think the housing is well made, I could do without the crenellated bezel, a feature you typically only see on tactical and tacticool LED flashlights.
The flashlight is priced at $80, but you can sometimes find it on sale for 10%-off. Dorcy manufacturers this flashlight for DieHard, and offers similar features in their XML 600 lumen flashlight.
I definitely recommend this for anyone needing a super bright long-lasting flashlight with incredible throw distance. If Dorcy or DieHard made a similarly styled model with a floodlight beam profile or focusable reflector for maybe $10-20 less, I would likely buy one.
Thank you to DieHard and Dorcy for providing the review sample unconditionally. Review samples are typically given away, donated, or retained for benchmark and comparison purposes.
