Great light!

Super bright light and easy to use. The main white light projects far and bright when used in the woods. The multiple colored lights are an extra benefit!

Best headlamp

This is by far the best headlamp I ever used. I use it for hunting, fishing, and general use. It’s dimmable rechargeable, waterproof, and very functional. Cannot recommend enough.

Great Headlamp -- Wish the Red Light Was Brighter

Black Diamond makes great headlamps. I think this is my fourth or fifth and they have all been great. Very bright, multiple settings, and comfortable to wear. If I have one criticism, it is the red/blue/green light isn't as bright as I would have liked. If you are using it for reading or small tasks, it works really well. Hunting and hiking with it on red wasn't as easy. I found myself having to slow down and even stopping on occasion to assess my route. Otherwise, great headlamp.

Good little head lamp, wish I bought the rechargeable

I love this headlamp and it's feature set. I've used it for everything, hunting, camping, working on cars. It can do it all, I do wish I had bought the rechargeable model because I change batteries on this frequently. The controls are easy to remember and do without looking.

This headlight has a decent brightness, but I’ve found it a little frustrating at times to cycle through the different settings. It also seems to automatically dim if you have it on for a longer period of time? I’ve had to turn it off and back on to achieve the same brightness. I’m assuming this is an energy saving function, but it is frustrating when you need to maintain that level of brightness. Otherwise this light is comfortable to wear and packs up well. I’ve used it around the house and for camping and backpacking.

Eats batteries for dinner and wants more for dessert

It takes 4 aaa batteries which makes it relatively heavy. Drains those batteries quickly… make sure to use the lock or you will find yourself in low power mode quickly. Feature functions are good, lots of options, button lock to avoid it turning on in your pack, etc. and bright. All that said, I am constantly nervous I am going to run out of batteries now which causes me to limit my use.

Great light

I use the Storm 400 on every hiking trip I take and also use it at home. Reliable light that doesn’t drain batteries at a rapid rate. The light is plenty lightweight and doesn’t make your head hurt when it’s worn for long periods of time. I would recommend this light to anyone who wants a high output light. I also like the red light feature for use when at a campsite or around others. Top notch lighting.

Good headlamp

Love the brightness, the latch was a little weak and broke pretty quick
