The M700i is the latest underwater video light from Nocturnal lights using the KIS (Keep it Simple) design philosophy. The M700i video light is ultra-compact, measuring at 5 and 1/4" long, 1" in diameter at the body, and 1 1/2" at the widest point of the light head. There are countless ways to mount the M700i directly onto your housing or arm using the YS or ball joint adapters, making it a perfect addition to your underwater camera and video setup no matter where and how you would like to mount the light. The light uses a twist on and off mechanism with two power settings, allowing you to switch between high and low output each time you turn the light on and off. On the high setting you can get 700 lumens of wide 80-degree beam that will add color and contrast to your videos, allowing you capture vibrant videos that pop out and speak to your audience. When shooting macros or using the M700i as a focus light you can use the low power setting with the power reduced to 40% for a softer touch and extended burn time and decreased light output. The aluminum light head acts as a heat sink so the video light can be used above water when shooting topside. The built in controller will monitor the heat generated by the bulb and cut down the power when it is appropriate. The double o-ring design that connects the light body and the battery compartment gives the M700i video lights a depth rating of 100 meters or 330 feet. The M700i uses two CR123 batteries as well as a rechargeable lithium ion battery from Nocturnal Lights. Both types of batteries will offer approximately 1.5 to 2 hours of usable light and up to 3.5-4 hours of burn time on the low setting. Both YS adapters and ball joint adapters are available for the M700i covering most of the arms in the market. Accessories are also available so you can be creative with how and where you want to mount the M700i video lights to your camera rig.
