Fenix SD20 Diving Light – 1000 Lumens


For the ultimate underwater exploration, the Fenix SD20 Diving Light is the perfect companion. Combining heavy duty CREE LED lighting with the ability to safely travel 100 metres underwater, the SD20 emits an amazing 1000 lumens that cuts through the darkness in or out of water. The SD20 also has the added convenience of one-handed operation, using a magnetic rotating ring. An integrated red LED provides additional utility and discreet illumination that won’t disturb sensitive sea-life. The SD20 runs on 2x 18650 rechargeable batteries, which are not included, but can be purchased below.
