I am a headlamp junkie. I keep two headlamps in my backpack with me at all times, and I usually have four spares in my vehicle for loaning to workshop clients who show up and aren't exactly well prepared to be outdoors.
What makes a headlamp great for a photographer? For me, I need a headlamp that has a bright white light, has multiple beam options from a wide & diffused spread to a spotlight effect, has a red lamp option for astrophotography, is durable, and has an IP67 rating which means it's fully submersible and dust proof. I'm also looking for a headlamp that is small enough that I will always keep it with me.
My favorite headlamp for several years now is the Storm made by Black Diamond. You can find headlamps that are a bit brighter, or have a few more features, but the Storm is the best balance of size, weight, cost, durability, and overall performance.
Features of the Storm Headlamp
• Dual-fuel design that allows you to power the headlamp with 3 AAA alkaline batteries or the rechargeable BD 1500 lithium-ion battery and charger.
• Settings include full strength in proximity and distance modes, dimming, strobe, red, green, and blue night vision, and lock mode.
• White LED outputs up to 450 lumens on max setting, 225 lumens on medium, and 6 lumens on low.
• PowerTap™ Technology allows instant adjustment between max output and dimmed power.
• Brightness Memory allows you to turn the light on and off at a chosen brightness setting without it reverting back to the default setting.
• IP67 rating means this is considered dustproof and waterproof; it can withstand submersion in water up to 1m deep for up to 30 min.
As you can see, the Storm ticks all of my boxes for a headlamp and then some.
