COAST FL97R: a headlamp with another way to change the light

The COAST FL97R adds spoken commands to a familiar piece of equipment. A headlamp already frees your hands while it is on; the more interesting question is whether you can change the light without interrupting what you’re doing.

This is a researched product spotlight, checked November 14, 2026. We haven’t tested voice recognition, beam quality, runtime or comfort.

The feature worth trying

COAST describes voice commands for changing brightness, beam shape and colors. It also lists warm and cool light, red and green beams, and a physical GLIDE FOCUS lever for adjusting between flood and spot.

For camp chores, the attraction is straightforward: adjusting a light while your hands are occupied could remove a small but repeated interruption. Whether it does that well depends on the circumstances. We’d want to try recognition while speaking normally, with a hood on and with everyday background noise. Those are questions for a test, not performance claims we can settle from the feature list.

We’d also learn the physical controls before leaving home. A new input method is most useful when it complements controls you already understand. Having to remember an unfamiliar command while searching for something in a bag could turn a convenience into another task.

Read the modes together

The published specification table pairs 830 lumens with 2 hours on high and 420 lumens with 5 hours on medium. It separately lists 1,250 lumens for Turbo, without a Turbo runtime in the table we reviewed. The headline 15-hour maximum should not be read as 15 hours at Turbo output.

Those distinctions matter more than choosing the largest figure. For repeated close work, we’d first assess whether a lower setting provides useful light without excessive glare, then consider how the battery plan fits the evening. We have not measured sustained output or the brightness curve over time.

Power and packing

COAST lists a ZX350 rechargeable battery or three AAA batteries, USB-C charging and an IP54 rating. Follow the model’s instructions for the chosen battery arrangement; disposable cells are not rechargeable through the lamp.

The same page shows inconsistent weights: 3.77 oz in the headline and 4.21 oz in the specifications. We haven’t resolved that difference, so we’d confirm the weight and included battery configuration before using either number for a precise packing comparison.

A practical checkout at home would include the cable, battery access and lockout control, followed by a short session doing an ordinary task. That reveals more about your relationship with the controls than a photograph of an illuminated lamp. It still wouldn’t replace a proper runtime or weather-resistance test.

Where it earns a place on the shortlist

The FL97R is interesting for people who regularly change lighting while their hands are occupied. If you normally choose one setting and leave it there, voice control may offer less value. Our preference would be to try the interaction first, rather than buy it solely for the maximum output claim.

Our COAST output-and-runtime guide explains how to compare mode tables. The camp-lighting Journal piece looks at when a headlamp, lantern or separately positioned work light fits the job. See COAST’s FL97R page for the current product and instructions.
