Fenix SD11 diving torch, though designed specifically for under water photography and video is equally at home on dry land for anyone requiring a beautifully smooth 110 degree pure flood beam. SD11 features a CREE XM-L2 Neutral-White LED for excellent colour rendition. This can also be combined with the Cree XQE red LED for better colour rendition at greater depths. Power can be supplied by either 2 x CR123 batteries or 1 x 18650 rechargeable battery.

From its centre position the premium feel magnetic rotary switch at the head of the SD11 diving light activates 500 lumen white light output with an initial click to the right. A second click then activates 1000 lumen white light output. From the centre position, a single click to the left activates Red + mode at 250 lumens, combining red light with white light. A second click to the left activates the battery level indicator which utilizes the red LED to indicate Sufficient - Low - Critical battery levels.

SD11 is certified 100 metre submersible and supplied with a multi purpose mount which enables the torch to be mounted to a camera hot shoe or hand grip, plus an action cam to be mounted above the torch giving a versatile set up for recording your adventures (please see images for details)

SD11 other features:

* Dual O-ring sealed tail cap
* Dual layer body for added corrosion resistance
* Supplied with high quality adjustable lanyard with soft silicone grip
* Battery level indicator (red LED): Red constant (OK), Red flashing (LOW), Red fast flashing (CRITICAL)
