This Bigblue CF-250 Focusable LED Dive Light (Silver) is a compact but powerful LED dive light. The 1 XR-E LED provides 250 lumens of light. The CF-250 is powered with 4 AAA batteries; both Alkaline or NiMH will work. It has a burn time of up to 2.5 hours. The light is constructed from aluminum alloy, and is anodized, to be anti-corrosive.
The CF-250 can be used as a back-up light for cave diving or as a primary for some diving situations. The light has a color temperature of 6500 °K, and a focusable beam angle from 6° to 31°. Just twist the front to go from a wide even beam to a concentrated hot spot. Using the narrow beam could be useful for looking under ledges for lobsters and other marine life. The wide-beam is useful to restore natural color underwater. The light also features a magnetic swivel switch that makes one-hand operation easy.
