On most backpacking trips last year, I carried the Black Diamond Iota Headlamp (my review). Its 150 lumens were plenty for 3-season conditions; it weighed only 1.9 ounces (56 grams) and packed away small; and I loved that it was rechargeable, so that I could keep AAA batteries out of the waste stream and so that I could recharge it mid-trip using the same portable battery that I use for my phone and inReach.
For spring 2020, the Iota has been updated and renamed — it has become the Black Diamond Sprint 225 ($45, 1.9 oz). An early production version was sent to me last fall for review.
Review: Black Diamond Sprint 225
The Black Diamond Sprint 225 Headlamp is technically new for spring 2020, but essentially it’s a brighter and updated version of the three-year-old Iota, which will be dropped from BD’s line. I’m uncertain if Black Diamond felt that the improvements warranted a rebrand or if “Sprint” speaks better to the intended end-use.
The key specs of the Sprint:
- 1.9-oz (56 grams)
- One TriplePower LED bulb with a non-adjustable oval flood beam
- Up to 225 lumens of light output (on “full power” using PowerTap)
- Rechargeable lithium battery
- IPX4 waterproofness rating (“splashing from any direction”)
- $45 MSRP

This winter, I’ve found the Sprint 225 ideal for night-running on Boulder’s bike trails, streets, and some very easy trails. Last fall, I carried it as a just-in-case light on long and adventurous trail running loops in the Indians Peaks and Rocky Mountain National Park. And this year I plan to carry it on most of my backpacking trips, which start in April and finish in September.
My only complaint about the Sprint 225 for backpacking is that it lacks a red-light. This night vision-saving feature is wonderful on group trips, and in camp it’s often the only light that I use. Because of this omission, the Sprint seems more optimized for moving (i.e. trail running and long day-hikes) than camping.
The Sprint 225 is not to be confused with the Black Diamond Sprinter 275 ($75, 3.7 oz), which is also new for spring 2020. That model is slightly brighter, powered by three AAA batteries (single-use or rechargeable), and has a second head strap.
The Sprint 225 uses one TriplePower LED bulb. Its light pattern is wonderfully smooth, with no distracting rings; it seems almost perfectly optimized for night-running and night-hiking — it focuses most of the light ahead, but still manages to illuminate the periphery. It’s a nice happy-medium between a spot beam (which makes you feel as if you’re running in a tunnel and which can be dizzyingly bouncy) and a flood beam (which doesn’t throw enough light out ahead).
Black Diamond reports that the Sprint 225 can maintain its max 225-lumen output for 1.5 hours; its minimum output, for 20 hours. I’m uncertain how BD tests its lights, but this seems roughly accurate — I learned the hard way that the Sprint 225 has enough power for one 60- to 90-minute night run, but needs to be recharged before a second one.
How does the Sprint 225 compare?
Black Diamond Sprint 225 vs Black Diamond Iota
Let’s start by comparing the Sprint to its predecessor. Both fill a similar niche in their price ($45 and $40, respectively) and size/weight; they have the same operating configuration; and they share many features, like the 3-LED battery meter and PowerTap.
The Sprint is 50 percent brighter (225 lumens vs 150), and it has a few small improvements. For example, the Sprint remembers its last brightness setting when it’s turned back on, whereas the Iota has an adjustable default. BD also reports that the Sprint’s lens is more efficient.
Black Diamond Sprint 225 vs Petzl Bindi
The Sprint 225 is brighter and less expensive than the Petzl Bindi, which has only 200 lumens and retails for $60. However, the Bindi has a red light. Moreover, it’s likely that Petzl will soon release an updated brighter Bindi.
Black Diamond Sprint 225 vs Nightcore NU25
The Sprint 225 weighs the same as the Nightcore NU25 but costs $10 more. The NU25 puts out 360 lumens and has a red light. If Nightcore could just work on their 1990’s era PC-like aesthetics, maybe they’d be onto something.
