Description

The CF450M is Bigblue’s mini light with an adjustable beam. Set it to a 7° narrow beam to put 450 lumens on one spot, or open it up to a 37° wide beam to light more of the scene. One small light covers both jobs.

Bigblue lists it as a backup light for advanced divers. It’s compact and efficient, and a tail-mounted magnetic slider switch gives quick, intuitive control, even in challenging conditions.

Three AAA batteries, alkaline or Ni-MH, run it for up to 4 hours. Bigblue includes the batteries, so it’s ready out of the box.

The body is anti-corrosive anodized aluminum, with tempered optical glass and a convex lens up front. It’s tested to 100 m, measures 35.5 mm across and 121.5 mm long, and weighs 193 g with batteries.

Want more from it? Bigblue makes FILYEL35 yellow and FILRED35 red filters, an FDK35 FluoroDive kit and a CLIPMNTCF mounting clip that fit the CF450M, all sold separately.

Pick Classic Black or Bright Blue, then choose your package: the light alone, the light with a neoprene glove made for mini lights, or the light with that glove and a neoprene pouch with retractor.
