I've participated in many night walks, including the Hood to Coast/Portland to Coast Relay, where flashlights or headlamps are required. When I spotted the Nathan Zephyr Fire at a race expo, I discovered Nathan had designed a practically-perfect runner's and walker's flashlight.

The Zephyr Fire comes in two versions, which vary in brightness. The Zephyr Fire 100 has a maximum intensity of 113 lumens.

That was very bright for lighting my way, and should illuminate over 67 meters (220 feet). The Zephyr Fire 300 takes that up to 308 lumens and illuminates 104 meters / 341 feet. Both have High, Low and Low Strobe modes.

In addition to the front light, both versions have a red back safety light, so you won't need a separate flasher/blinking light.

Angle and Hand Strap: The Zephyr Fire is angled at 24 degrees, perfect for illuminating your path when walking or running. Even better, it has an adjustable elastic hand strap so you don't have to keep a tight grip on it. Just slip on the triangular hand strap and you can relax your hand or keep a loose grip. That prevents raising your blood pressure due to gripping something while running or jogging. The Zephyr Fire is lightweight so you won't increase your risk of strain.

Charge via USB: The biggest problem with bright flashlights is battery life.

You can recharge the Nathan Zephyr by plugging a USB cable into an adapter plug-in or computer. Perfect, I already have those in my car and office. It takes 5-6 hours for a full charge. The burn time for the Hi - 5+ hours, Low - 8 hours, Low/Strobe - 15 hours. For the 300 it is Hi - 3 hours, Low - 6 hours, Low / Strobe - 12 hours.

I am happy I got the 100 as it is impressively bright and has a longer burn time for the high beam before a recharge.

Audible Safety Alarm: You can press the siren button on the handgrip to set off a siren alarm and alert others if you are in distress. My only quibble with this is that the first time I used it, I kept pressing that button rather than the power/mode button. The siren is loud but not overly loud. More: Street Safety for Walkers

Walking or Jogging with the Nathan Zephyr Fire Flashlight
It's not easy to hold a flashlight at the perfect angle when you are out for a walk or run. The design of this flashlight eliminates that problem. I've had lots of trouble with headlamps and LED hats because the beam doesn't reach the ground at the correct points ahead of me to light my path.

A flashlight isn't a perfect solution if you use good walking arm motion, as the beam will swing back and forth with your arms. But the built-in angle helps you keep the beam in the right area.

I've seen many a broken flashlight due to them slipping out of your hand.

That is very unlikely to happen with the triangular hand strap.

This flashlight is weather resistant IPX4, it should be OK with a little rain, but it isn't built for immersing in water.

Bottom Line on the Nathan Zephyr Fire Flashight
I am very happy with this purchase and I will keep it handy in my car for emergencies and in my walking pack for walks. I needed it when my friends met for a pre-dawn walk and it performed very well. The only concern would be remembering to recharge it after each use.
