Description

The Red Spot Light Mini is a thin, compact signaling light. Bigblue’s 2027 catalog calls it the Red Dot Mini Light. Instead of a flood of light, it puts out a sharp red dot, made for underwater communication: point to a critter, get your buddy’s attention or lead a group of divers.

The dot is 650 nm, with an output below 5 mW, and Bigblue rates burn time at up to 7 hours. It runs on two AAA batteries, alkaline or Ni-MH. There’s no button: twist the bezel to turn it on and off.

The body is anodized aluminum alloy with tempered optical glass at the front, tested to 100 meters. It measures 17 mm across and 114.1 mm long and weighs 60 g with batteries. A lanyard comes with it, and Bigblue’s CLIPMNTSPOT mounting clip, sold separately, holds it on your gear.

Bigblue lists it as an advanced and backup light. Prefer green? The Green Spot Light Mini is the same light with a 520 nm green dot.
