FreeFly Rechargeable Ultralight Headlamp, Mini-USB Rechargeable, 75 Lumens, Red Night Vision

This is an amazing headlamp. For its size it is very bright. The battery is decent, I was able to around 3 hours out of it around camp and did not notice the headlamp dimming. It is bright enough to hike by and USB rechargeable which is its greatest benefit since most backpackers carry some kind of power bank. It's the lightest rechargeable headlamp I've found and cheaper than other options (black diamond, petzl etc.) It's one of my favorite pieces of backpacking gear, I highly recommended this for those seeking to lower their base weight.Update.Still a great headlamp. Replaced the headband with some shockcord and a cordlock and it weighs 1.2oz! I currently swap between this headlamp and a nitecore NU20 depending on the trip. It may not always be my go to light as I am experimenting with keychain lights that weigh less than 1oz to see if they will be an acceptable replacement. This still is the best deal for a decent, very light, rechargable headlamp.

Super bright! The high beam lights upwards of half mile across a river valley we were hiking through. It looked like a stage spotlight. Recharger completes the five star rating: no more trips to the pharmacy to purchase pairs pairs of watch batteries.Don't forget to remove the clear film from battery cartridge in order to allow connection

I give this product four stars only because it is difficult to me to assign perfection to anything. I bought this headlamp, and a Firefly made by the same folks. The Firefly was up and running as soon as I put the battery in. The FreeFly did nothing except put on a remarkable blinking light show when plugged in to charge.Knowing I may not much of a bright medic myself, I dropped a line to customer service. Although it was New Year's Eve weekend and I expected no reply for a few days, CS replied within a few hours. Turns out the battery is removable, and is shipped with a piece of tape over the terminals. Once this was addressed, the light charged and performed as expected.I'm a paramedic and an ultralight hiking enthusiast. The Firefly is for my pack. It packs a lot of function in a tiny package, and a spare battery only costs a few grams. The FreeFly is just a little heavier, but still plenty compact to go into a cargo pocket, and recharges anywhere there's a USB port. Both offer multiple levels of white LED goodness, as well as a red option which saves one's night vision. Overall satisfied with both purchases, other than the fact that immediately after my purchase the FreeFly went on sale for a good bit less than I paid. Such is life.The primary reason for writing this review is that I found the customer service experience to be outstanding. Immediate response on a holiday weekend to kind of a dumb question. I think this is an outfit worth supporting.

Bought two. REMOVE THE BATTERY PROTECTOR WHEN YOU GET IT.One was defective in that it would never stop "charging" (blinks when plugged in and charging, then solid when done).This resulted in the defective unit getting overcharged (multimeter showed battery topped up over capacity and device was still trying to charge itself, blinking away).The working unit is great for lightweight travel. Decent light output & like the multiple modes

Great idea. So far seems to hold charge well. Purchased for backpacking.

Ultralight!
