Black Diamond just refreshed five headlamps in one day. That is a lot of new ways to blind your tent-mate by accident.
Here is the short version. The new Megawatt is a 3,000-lumen light for ski touring and mountain biking. The Storm+ and Storm are rebuilt, waterproof all-rounders. The Spot and Cosmo are the everyday lights that run on AAA batteries or a rechargeable pack. Black Diamond announced the lineup on October 29, 2026, and all five were listed on its own site the same morning.
This is a first look built on Black Diamond’s own numbers: its product pages, its instruction sheets and its press release. We have not had these lights on our heads yet, so nothing below is a test result.
Quick pick: which one is yours?
- Most people (camping, hiking, the car glovebox): Black Diamond Spot, $59.95. It puts out 450 lumens, has a beam that reaches up to 116 m, and runs on AAAs or a rechargeable pack.
- Bad weather, gloves, alpine starts: Black Diamond Storm+, $99.95. It is the longest-reaching small light in the lineup at 149 m.
- Fast downhill in the dark (skis or a bike): Black Diamond Megawatt, $379.95.
- A cheap, small backup: Black Diamond Cosmo, $44.95.

What’s new across the lineup
Black Diamond calls this the biggest refresh of its headlamp range in years. Its press release names these changes across the range:
- More output across the range.
- USB-C charging becomes standard.
- Simpler controls that are easier to use in the field.
- Recycled materials in headbands and internal parts.
- A brand-new top model, the Megawatt, with a wireless remote and action-camera-style mounts.
Two quick terms before the specs. Lumens are the total amount of light the lamp puts out. Beam distance is how far the beam reaches before it gets too dim to be useful. A light can have big lumens and a short beam if it spreads the light wide. Our Lumens Explained page covers the details.
Black Diamond rates burn time to the ANSI FL-1 standard. That means the time until the light drops to 10% of its starting output, not the time it holds full brightness. Black Diamond also lists a “reserve” time: extra time at a very dim level after that point.
Black Diamond Megawatt: for people who think 750 lumens is a night-light
The Megawatt is the new flagship and a different kind of light from the rest. The lamp sits on your head or helmet. A separate 50.32Wh battery pack rides on a strap or in your pack. A wireless remote clips to a ski pole, pack strap or handlebar so you can change brightness without reaching up. Black Diamond says it is the brand’s first headlamp built for fast action sports like ski touring and mountain biking.
- Max output: 3,000 lumens from six LEDs, plus one red LED (Black Diamond)
- Beam distance: Black Diamond hasn’t published one for the Megawatt, so check throw before you buy if reach matters
- Burn time: Black Diamond’s product page and press release say 4 hours at max output, and up to 44 hours max burn time. Its instruction sheet lists 4.5 to 10.5 hours on the High range (3,000 down to 1,200 lumens) and 15.75 to 44 hours on the Low range (800 down to 100 lumens).
- Battery: 50.32Wh rechargeable pack with an LCD that shows live burn time and a red safety flasher. USB-C charges in and out, so the pack can also top up your phone.
- Weight: 75 g for the light body. Black Diamond’s product page and press release say 480 g total with the battery pack, but its instruction sheet says 426 g. We are showing both until Black Diamond settles it.
- Water and dust: IP67, which Black Diamond describes as sealed against immersion in 1 m of water for 30 minutes
- Mounts: headband plus a GoPro-style quick-release mount, with two adhesive helmet mounts included
- Price: $379.95 at Black Diamond. A spare Megawatt battery is $169.95.
Who it’s for: dawn-patrol skiers and night riders who move fast and need a lot of light far ahead. Who should skip it: almost everyone who camps, hikes or walks the dog. It costs more than the other four lights combined.
Black Diamond Storm+
The Storm+ is the reach-out-and-touch-it light of the regular-sized group. It pairs a wide flood lens with a focused spot lens. Black Diamond says the spot lens comes from its Icon 700. It also has big buttons you can press with gloves on, and red, green and blue night modes.
- Max output: 750 lumens
- Beam distance: 149 m on max, 68 m on medium (200 lm)
- Burn time: 4.5 hours on max, 20 hours on medium, 80 hours on low (35 lm)

- Weight: 114 g
- Water and dust: IP67

- Price: $99.95 at Black Diamond (Pewter or Black)
Who it’s for: climbers, winter hikers and anyone who wants to see the next trail marker, not just their boots.

Black Diamond Spot
The Spot is the one we would point most people to first. It runs on three AAA batteries (included) or Black Diamond’s BD 1500 rechargeable pack, which is sold separately for $24.95 and charges inside the light over USB-C. That means you can buy batteries at any gas station on a road trip. PowerTap lets you jump to full power and back with a tap on the side.
- Max output: 450 lumens
- Beam distance: 116 m on max, 84 m on medium (200 lm)
- Burn time on max: 2.6 hours on AAA alkalines, 3.4 hours on the BD 1500
- Burn time on medium: 5 hours on AAA, 8 hours on the BD 1500
- Burn time on low (6 lm): 200 hours on AAA, 150 hours on the BD 1500
- Weight: Black Diamond’s product page and press release say 86 g. Its instruction sheet shows 75 g (42 g light plus 33 g of AAAs).
- Water: IPX7 (Black Diamond says it is tested to run 1 m underwater for 30 minutes). It has no dust rating.
- Price: $59.95 at Black Diamond (five colors)
Who it’s for: campers, car campers, and anyone who wants one headlamp that does a bit of everything.

Black Diamond Cosmo
The Cosmo is the small, simple one. It has the same AAA-or-BD 1500 setup as the Spot and adds a second switch so you don’t have to cycle through modes. Its red LED has its own brightness control and a strobe.
- Max output: 350 lumens
- Beam distance: 62 m on max, 42 m on medium (175 lm)
- Burn time on max: 3.2 hours on AAA alkalines, 5 hours on the BD 1500
- Burn time on low (6 lm): 200 hours on AAA, 120 hours on the BD 1500
- Weight: Black Diamond’s product page and press release say 88 g. Its instruction sheet shows 75 g (42 g light plus 33 g of AAAs).
- Water: IPX7
- Price: $44.95 at Black Diamond (four colors)
Who it’s for: a backup for the car, a kid’s first real headlamp, or a power-outage drawer. The beam is short, so it isn’t a trail-finder.

How they compare to headlamps we already cover
Megawatt vs Fenix HM75R PRO. On paper the Fenix puts out more total light (3,500 lumens, spot and flood together) and Fenix rates its beam to 398 m. It weighs 214 g with battery and band, is rated IP68, and Fenix listed it at $139.95 (October 23). The Megawatt costs much more and weighs more in total. In return you get the remote, the helmet and handlebar mounts, a 75 g light on your head with the battery somewhere else, a live burn-time screen and a pack that charges your phone. If you ski or ride fast, those extras are the point. If you walk, the Fenix is the better deal on paper.
Storm+ vs Acebeam H18. The H18 has the much bigger lumen number (4,000 on the 6500K version), but Acebeam’s own chart shows turbo dropping to 700 lumens after 30 seconds. Acebeam rates its beam at 162 m, and the kit weighs 190.6 g. The Storm+ is far lighter at 114 g, reaches 149 m by Black Diamond’s rating, and adds red, green and blue modes. Our HM75R PRO vs H18 page listed the H18 at $109.90 (checked October 27), about $10 more than the Storm+.

What we don’t know yet
- No independent tests yet. Every number here is Black Diamond’s own claim. There weren’t published third-party output or runtime measurements for the 2026 lights as of this writing.
- Megawatt beam distance. Black Diamond hasn’t published it, so check throw before you buy if reach matters.
- Megawatt weight and max runtime. Black Diamond’s product page and instruction sheet disagree (480 g vs 426 g, and 4 hours vs 4.5 to 10.5 hours). We’ll update this page when Black Diamond clarifies.
- Spot and Cosmo weight. The product pages say 86 g and 88 g. The instruction sheets say 75 g with batteries.
- Amazon listings. Confirm Spot 450, Storm 550, Storm+ 750, and Cosmo 350 in the title (older Storm 450 / Spot 400 / Cosmo 350 lookalikes still show up). Megawatt: buy from Black Diamond for now.
FAQ
Which Black Diamond headlamp should most people buy?
The Spot. At $59.95 it has 450 lumens, a beam Black Diamond rates to 116 m and IPX7 water protection. It also runs on AAAs or the rechargeable BD 1500 pack.
How do I tell the new models from the old ones?
Look at the name and the lumen number. The 2026 lights are sold simply as Storm+ (750 lm), Storm (550 lm), Spot (450 lm) and Cosmo (350 lm). Older models usually have a number in the name, like Storm 450 or Spot 400. Be careful with the Cosmo: the older Cosmo 350 is also rated at 350 lumens. The redesigned Cosmo has a second switch.
Do the Spot and Cosmo come with a rechargeable battery?
No. Black Diamond includes three AAA batteries. The BD 1500 rechargeable pack is sold separately ($24.95 at Black Diamond), and it charges inside the light over USB-C.
Is the Megawatt waterproof?
Black Diamond rates both the light and the battery pack IP67, which it describes as sealed against immersion in up to 1 m of water for 30 minutes. It is also rated dustproof.
