Black Diamond Spot or Storm: which headlamp should you choose?
Short answer
For the current models, choose the Spot if AAA backup and an optional rechargeable battery fit your trips; consider the Storm if USB-C charging fits your routine. Compare controls, beam modes and fit before maximum lumens. These current 450-lumen Spot and 550-lumen Storm models differ from older similarly named headlamps.
The most useful difference between these current Black Diamond headlamps is the power arrangement. Decide how you will recharge or replace batteries on the trip before comparing the brightness number.
Which versions are we comparing?
We compare the current 450-lumen Spot (product family 620746) and the current 550-lumen Storm (620747), not older models with similar names.
| Current model | Manufacturer-listed maximum | Power approach | Weight | Maximum burn time | Water rating |
|---|---|---|---|---|---|
| Spot, product family 620746 | 450 lumens | Three AAA batteries or optional BD 1500 rechargeable battery; USB-C charge-in with the BD 1500 | 86 g | 200 hours | IPX7, “up to 1 meter underwater for 30 minutes” |
| Storm, product family 620747 | 550 lumens | USB-C rechargeable, “Serviceable” 1800 mAh Li-ion (3.6V in features, 3.7v in specifications) | 102 g | 70 hours | IP67, “immersion up to 1m for 30 minutes” |
These are the current Spot and Storm listings checked in September 2026. The Spot 400-R, Spot 400, Storm 450 and Storm 500-R have separate specifications. A discounted older model may still suit a trip, but its charging connector and battery arrangement should be checked independently.
Every figure in the table is Black Diamond’s listing, not our measurement. Neither product page says which setting its maximum burn time applies to, and neither names a test standard.
When does the Spot make sense?
The Spot’s choice of AAA cells or an optional rechargeable battery is useful when you want to decide between carrying replacement cells and managing recharging. Its instruction sheet says to “Use AAA alkaline, lithium or Black Diamond BD 1500 Li-Ion rechargeable batteries.” Budget for the rechargeable battery separately if that is the intended setup; Black Diamond lists the BD 1500 as a 1500 mAh Li-ion cell “compatible with all BD Dual Fuel headlamps and lanterns.” Test the fit with any hat or hood you expect to wear.
PowerTap and multiple lighting modes are features to evaluate with your own hands. Consider whether you can find the intended setting without cycling through unwanted light around other campers. We have not tested the controls with gloves or measured beam quality.
When does the Storm make sense?
The current Storm suits a kit organized around USB-C charging. Black Diamond describes two oversized buttons for use “with gloved hands,” plus red, green and blue options. Those controls may appeal if changing settings quickly matters more to you than carrying disposable spare cells.
The 100-lumen difference in listed maximum output is only one part of the choice. Beam distribution, the setting you actually use and how power is managed over the trip can matter more than the maximum. The Storm page calls its battery “Serviceable” without saying what that involves, and lists it at 3.6V in one place and 3.7v in another.
What should be checked before leaving?
Charge or fit the correct batteries, learn the controls, and decide what backup light the trip requires. Check the exact model’s water-protection instructions and transport lockout. Neither a waterproof description nor a bright maximum tells you how long a useful setting will last.

The short version
Choose between the current Black Diamond Spot and Storm by how you will power them, not by the 100-lumen gap. The 450-lumen Spot runs on three AAA cells or on the BD 1500 rechargeable battery, sold separately, which then charges over USB-C; Black Diamond lists it at 86 g, IPX7 and a 200-hour maximum burn time. The 550-lumen Storm runs on its own 1800 mAh lithium-ion battery charged over USB-C, with two glove-friendly buttons, IP67, 102 g and a 70-hour maximum. Neither page says which setting those burn times describe, and the Storm page lists its battery at two voltages without explaining what “serviceable” means. Older Spot and Storm models are different lamps with their own specifications.

Quick answers
- Is the current Spot the same as the Spot 400-R?
- No. The current Spot 620746 is listed at 450 lumens with dual-fuel capability. The Spot 400-R is a different model; check its own specifications.
- Does the current Spot include the BD 1500 rechargeable battery?
- The current Spot listing describes the BD 1500 rechargeable battery as sold separately; the lamp also accepts three AAA batteries.
- Which batteries can go in the Black Diamond Spot headlamp?
- Black Diamond's Spot instruction sheet says to "Use AAA alkaline, lithium or Black Diamond BD 1500 Li-Ion rechargeable batteries" and warns "Do not mix old and new batteries or different battery types." The Spot takes three AAA cells or one BD 1500. The sheet does not mention NiMH rechargeable AAA cells either way, and the product page lists USB-C charge-in only "with BD 1500 battery (sold separately)."
- What does "serviceable" mean on the Black Diamond Storm battery?
- Black Diamond doesn't say. The Storm product page describes a "Serviceable" 1800 mAh lithium-ion battery but does not explain who can replace it or how, links no spare battery, and the Storm instruction sheet says nothing about battery replacement. The same page also disagrees with itself on voltage, listing "3.6V" in the features and "3.7v" in the specifications.
- At what brightness does the Black Diamond Spot reach its 200-hour burn time?
- Black Diamond doesn't say. The Spot product page lists a maximum burn time of 200 hours and a maximum output of 450 lumens, but does not state which mode, which battery (AAA or BD 1500) or what end point the 200 hours assumes, and it names no test standard. The Storm page has the same gap for its 70-hour figure, so the two numbers can't be compared with each other.
