"This is a spare that I keep in the truck in case of emergency. It was nice and bright when I tested it out."
"The headlamp is bright, functional, and stays alive for a while. I've had it at max brightness for over an hour. However, the controls are strange. It will turn on to whatever color/level you left it on. So the "buttons" switch depending on your settings beforehand."
"Needed a lamp for local night excursions to walk the dog and find what she leaves behind. This lamp works perfectly. Red light is perfect for most tasks and especially handy when anyone walks with me so they aren’t blinded by my effervescence. White light is really only needed for the deep search and rescue. Easy to operate and is holding its battery life nicely."
"I have a BD headlight that directly charges via Micro USB and I LOVE it. This one comes with Duracell batteries and you can purchase a lithium battery that can be charged but this is buried in the description. This was not evident while purchasing. Now I have another headlight that needs batteries unless i want to purchase the lithium battery that it should come with and have the option to use batteries."
"I love this."
"Awesome headlamp just to tuck away in a bag and was a lot brighter than other lamps this size! great light adjustability and super comfy."
"I bought this as a gift for my husband who often tries to hold/position a flashlight while working on projects in our house. Very, very bright. He is beyond happy with it!"
"This is the worst headlamp that I have ever used. Red lights are essential for camping so that you don't blind other people in your party. The red light in this headlamp is useless. You can't see your own hand in front of your face on either setting (high or low). To be fair, the white light is amazing and it lights everything up like heaven. But without a good red light, this headlight is useless in my opinion."
"Great headlamp. Got this for my son to use while hiking and hunting. Simple to use and light weight. Good bright light and red light worked nice as well! Love that this can use the rechargeable batteries to save some money in the long run!"
"nice and bright> like the adjustable light feature. lith ion rechargeable is especially great on battery savings. 4-6 hours of run tends to eat into batteries. recharge is quick. had the 300 series but I'm going to love this one more."
