1,000 LUMENS
The SureFire Maximus rechargeable variable-output LED headlamp delivers an amazing 1,000 lumens of light—enough to illuminate your entire campsite. If that's too much light, you can dial it down to 1 lumen—or any level in between—for closer work, preserving your dark-adapted vision, or extending the runtime. A large knurled dial permits output control with one hand—even if it's gloved or numbed by cold. One hand can also aim the light right where you want it since the light assembly rotates up and down 90 degrees. The SureFire Maximus utilizes a high-performance LED and a custom reflector to produce a wide, diffused beam optimized for your natural field of vision, but which also provides impressive reach at its max output setting. Power comes from an integral rechargeable lithium-ion battery that can provide years of use; chargers for both wall-type AC outlets and 12-volt DC vehicle accessory outlets are included. A fuel gauge on the headlamp gives battery charge status, and a long-running SOS beacon provides an extra margin of safety if needed. Built from tough, lightweight magnesium, the SureFire Maximus thrives in harsh conditions. It's also comfortable to wear, thanks to its no-chafe fine-weave headband and moisture-wicking Breathe-O-Prene® forehead pad.

Industry Standard Headlamp Without Any Peers

This light is amazing. Buy it early in life so you can enjoy it longer.

It also works well simply hanging around your neck like a necklace. With the adjustable up/down pivot, you can walk in the darkness while illuminating your path and enjoying a hands-free experience.

The adjustable lumen output is very handy, and at 500 lumens it's very bright, too.

Well done, Surefire!

I sent it back for replacement or repair - I'm told that there is nothing wrong

It puts out a lot of light, but the fact it cannot be focused to a high-intensity spot is a very major weakness. This was indicated in some of the reviews but I decided to take a chance on it. If you need to focus your headlight, do not buy this one. If Surefire made a lens that would focus the light, it would be much better. Battery life is also very short at the high output (less than 1 hour). It's also very pricey. I regret buying it, but now that I have used it probably should not return it.

Update 8-15-22: On several occasions now, I have put the light away after just fully charging it and when I went to use it, the battery was completely dead.

Update 9-3-13: I finally sent this light in to Surefire for repairs or replacement with the following message: "This light has been disappointing since I first purchased it. Battery life has always been very short (less than 1 hour). Many times, when I go to use it after it has had a full charge and I have stored it in the bag it came in, it will be completely dead. The last time I used it, I took it directly off the charger and the charge indicator light was orange. The light was very dim and flickered. I haven't attempted to recharge it."
I just spoke with customer service on the phone to get an update. I was told that there is nothing wrong with the lamp and that they are going to send it back to me. Well, I guess it's $185 down the tube. I would definitely not recommend it.
The customer service agent did tell me on the phone that the light must not be charged for more than 24 hours. This in not stated in the paperwork with the light.
