Description

The AL450STROBE, called the AL450STRB in Bigblue’s catalog, is a small LED dive strobe built for emergencies. It sends out a strong flashing signal so you’re easier to spot, and Bigblue says it improves safety and communication underwater.

It flashes 450 lumens of 6500K white light through a wide 270° beam at 60 pulses per minute. On 3 AAA batteries, alkaline or Ni-MH, Bigblue rates it for 36 hours. That’s plenty for a long dive day, and the batteries are easy to find when you travel.

A tail-mounted push button turns it on and off. Bigblue says it works quickly and reliably, even while wearing gloves.

The body is anti-corrosive anodized aluminum, tested to 100 m. It measures 35.5 mm across and 136.7 mm long and weighs 131 g with batteries.

Bigblue lists the NP ball joint connector as an option, to mount the strobe on a 1-inch ball. A lanyard is in the box.

Want color? This strobe flashes white only. Bigblue’s STRB-RGB flashes white, red, blue and green.
