Extreme Beam OSR-800 Headlamp Review

Extreme Beam’s OSR-800 is marketed primarily as an LED Headlamp designed for use during camping, hiking, and other outdoor expeditions, but it’s really an all-around utility headlamp flashlight that’s right at home in your tool box or glove box.

The OSR-800, while designed for outdoor use, is just at home in home improvement or car care situations.

OSR-800 Features

Right out of the package, the OSR-800 is easy to use and has some nice features that will come in handy just about anywhere.

  • 160 Lumens
  • 550 Foot Range
  • Weight – 4 oz. (with Batteries)
  • Modes-High/Low/Flash/SOS
  • Focusable Beam
  • Adjustable Headband
  • 90 Degree Tilt
  • Water Resistant

The OSR-800 beam is incredibly bright and can be adjusted from a small pinpoint for seeing at a distance, all the way out to a wide patten that can illuminate an entire 8-foot wall from a distance of about 12 feet.

At 160 lumens, this headlamp is incredibly bright.

The pinpoint focusable light works well for seeing distant objects.

From a distance of 12 feet, the beam easily covers an 8-foot spread.

The focus-adjustment ring is of the push-pull variety. That makes it pretty simple to adjust with just one hand.

The push/pull focus knob can be easily adjusted with one hand.

It even has a beam-scale printed on it, although it would be hard to see while wearing the headlamp, unless you have extendable eyes 🙂

The strap is adjustable and comfy, and the over-the-top strap is easily removed if you prefer just the head-band style.


The LED chip is rated at 50,000 hours. That translates into over 5 1/2 years of constant use, so it’s not likely you’ll wear it out any time soon. Extreme Beam’s OSR-800 runs on 3 AAA batteries, which install by splitting the case in two by depressing the release buttons on each side. The unit’s average run-time is 24 hours on a fresh set of batteries, depending on the mode selected, of course.

The OSR-800 runs for up to 24 hours on 3 AAA batteries.

Extreme Beam OSR-800 Review

Overall, this is a high-quality, well constructed LED headlamp that appears would provide years of rugged use. The SOS feature is handy, especially if you plan to use it hiking or camping. There’s also a red ring around the barrel of the light that is easily seen from the side. This is a great safety feature if you’re changing a tire on the side of the road, where every little bit helps in the avoidance of being hit.

Extreme Beam

The OSR-800 easily tilts a full 90 degrees.

For the under-$30 price, the OSR-800 is a nice addition to your flashlight arsenal, whether you’re using it for camping, home improvement, or tactical/survival purposes. I don’t think you’ll be disappointed in the performance or quality of this headlamp.
