Info from Zebralight
• LED: CREE XLamp XR-E Q5 bin
o Diameter 18.3 mm (3/4”)
o Length 66.5 mm (2 5/8”)
• Battery: One AA size alkaline, 1.5v lithium primary, NiMH rechargeable, or 3.7v 14500 Li-ion rechargeable. Reverse polarity protection.
• Weight: 58g (2oz) with the headband and an alkaline battery
• Performance: Constant ratio output level spread. Fully regulated.
o Low 2.6 lm for 3.5 days
o Medium 13 lm for 19 hr
o High 66 lm for 2 hr 20 min
Light levels are out of the headlamp values. Runtimes performed using a Sanyo 2700 mAh NiMH battery.
• Beam Type: 120 degree flood
• Electrically conductive aluminum body provides inherent EMI/RFI shielding characteristics
o Impact resistant LEXAN polycarbonate lens.
o Aluminum alloy case with durable hard anodized finish.
o Glow in the dark silicone bracket.
• Tailcap twist switch.
• Operation sequence: OFF, low, OFF, Medium, OFF, high. If the light is turned off for more than 5.6 seconds, the light level resets to low
H50 Q5 uses a single AA battery and is very UL. The double O ring twisty is more water resistant and most headlamps as there is no real point for water entry. The headlamp runs for a very very long time regulated on one battery. Being regulated the H50 can use standard alkaline, NiMH and lithium AA batteries. The runt time on low seems about the same no matter the chemistry however to get the longer medium and high runtimes NiMH or lithiums are recommended. But has some decent runtimes on cheapo alkaline too.
The output is pure flood with very little throw.
This makes for a great camp/power outage headlamp but there are some limitations if throw is needed. My EOS with 20ish lumens on medium can out throw the H5O with 66 lumens on high. But the flood is better for near work that is often what a headlamp is used for. One thing I like about the H50 beyond cheap batteries is the low setting. 2.6 lumens is not going to blaze your though the dark woods but worked well for my general low light camp use. With the higher settings I could see in all directions at the same time without turning my head due to the great flood. But this is paid for in terms of shorter throw. Makes for a good lantern tooPros.
1. Nice modes. Low enough low good medium and bright high.
2. Very efficient regulation. Long runtime. Nearly 4 days regulated on low with one AA battery.
3. Solid aluminum construction.
4. Lots of accessories packed along with the headlamp.
5. Tail twisty tends to be more reliable than a switch.
6. Pure flood light.Cons.
1. Very little throw for such a high lumen headlamp.
2. More expensive than other headlamp options.
3. Lack of clicky switch means two hands are needed to change modes.
4. Like all LEDs there are some variations in tint.
5. I wish they included a non glow in the dark holder.Conclusions:
I like the H50 within its limitations. Not something I would use for throw but for nearly everything else it works very well. The runtimes, weight, pack size and use of one AA battery combines to make a nice little headlamp. Bright enough to walk on good trails/roads and long enough runtime for extended camp use.
