Coast FLX10R Rechargeable Headlamp — 1000 Lumens, USB-C, IP67 Waterproof, Dual Power

Coast FLX10R Rechargeable Headlamp overview

The Coast FLX10R Rechargeable Headlamp packs a lot into a 3.46-ounce package: 1000 lumens on Turbo, a beam that reaches about 180 feet, and eight light settings — flood low/medium/high, spot, a combined mode, Turbo, and red and green night-vision beams. The headline feature is Coast's RECHARGEABLE+ dual-power system: it runs on the included USB-C rechargeable battery, and if you can't charge, you swap in 3 AAA alkalines for backup — so it never leaves you dark on a long job. It's also genuinely rugged, built to IP67 (dust-tight and submersible to 1 meter). See our best work lights guide and the work lighting collection for where it fits.

Read the numbers right: the 1000 lumens is Turbo, the maximum burst, while the up-to-15-hour runtime is on the lower, more efficient modes — step down from Turbo when you want the light to last. The silicone-lined adjustable strap sits securely on your head or over a hard hat, which makes it a natural jobsite headlamp; if you're choosing a hat to pair it with, our best hard hats and hard hat for construction guides help.

Where it fits

It's a versatile hands-free work and outdoor headlamp — construction, maintenance, automotive, utility, and camping — with the dual-power system and IP67 rating that suit a jobsite. The red and green beams add night-vision utility for gauge reading, wildlife, and close work. Because the strap fits over a hard hat, it slots neatly alongside head protection; for classified or hazardous-location work, though, reach for a certified intrinsically safe light and pair it with atmospheric monitoring from the gas-detector lineup — see the best personal gas detector guide.

Frequently asked questions

What is the output and beam?

It reaches 1000 lumens on Turbo (its maximum) and casts a beam up to about 180 feet, with eight total light settings that let you dial flood, spot, or combined output up and down for the task.

How long does it run on a charge?

Up to about 15 hours on the lower, more efficient settings. Turbo's 1000-lumen output is the maximum burst and draws down faster, so step to a flood or spot mode for long runtime.

How is it powered — rechargeable or batteries?

Both. Coast's RECHARGEABLE+ system means it runs on the included USB-C rechargeable battery, or you can drop in 3 AAA alkaline batteries as backup power when you can't charge — useful on long jobs or in the field.

Is it waterproof?

Yes. It's built to IP67, which means it's dust-tight and protected against submersion in up to 1 meter of water — genuinely waterproof, not just splash-resistant.

What are the eight light modes?

Flood low, medium, and high; spot; a combined flood-and-spot mode; Turbo for maximum output; and red and green beams for night vision. The colored modes preserve your dark adaptation and reduce glare in close work.

Does it fit on a hard hat?

Yes. The silicone-lined adjustable strap is designed to sit securely on your head or over a hard hat, so it works for construction and industrial use as well as general tasks.

How much does it weigh?

About 3.46 ounces per unit, which is light enough for all-day wear without neck strain, especially on a hard hat where the weight sits on the shell.

Is this a single headlamp or a 2-pack?

The Coast FLX10R headlamp is a single unit, but the linked Amazon offer is a 2-pack — so confirm the quantity on the listing before you buy if you only need one.

What are the red and green beams for?

Red and green light let you see without destroying your night vision or blinding people around you — handy for map or gauge reading, wildlife, and any close work where a white beam would be too harsh.

Is the FLX10R intrinsically safe?

No. It is a general-purpose work headlamp, not intrinsically safe. Do not use it in a flammable or explosive atmosphere; classified hazardous locations require a certified intrinsically safe light.

What jobs is it built for?

Construction, maintenance, utility, automotive, and any hands-free task, plus outdoor use like camping and hiking. The hard-hat fit and IP67 rating make it a solid jobsite headlamp.

How does it charge?

Over USB-C, so you can top it up from a laptop, wall adapter, or power bank with a common cable. When you can't charge, the AAA backup keeps it running.
