The M700t technical LED dive light is the latest dive light from Nocturnal Lights using a KIS (Keep It Simple) design philosophy. The M700t dive light is ultra compact, measuring at 5 1/4" long, 1" diameter at the body, and 1 1/2" diameter at the light head. The M700t dive light is so small and light it can be held, mounted, and stored away as if you are not diving and traveling with extra gear.
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 550 lumens of white, narrow 15-degree beam that will penetrate through water, allowing you to signal divers, look into crevices, and light up the vibrant colors of marine life during your dive. On the low setting you can reduce the power to 40% for a less intense beam and a longer burn time of up to 4 hours.
The aluminum light head acts as a heat sink so the light can be used above water as a flashlight. 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 seal that connects the light body and the battery compartment gives the M700t dive lights a depth rating of 100 meters or 330 feet.
A neoprene hand mount that can mount one or two M700t dive lights is available for a hands free diving experience and it is made to comfortably fit over any bare hand or glove. With one M700t you can get 550 lumens of water penetrating power, double up for a total of 1100 lumens mounted comfortably on the back of your hand. Additional accessories such as the aluminum Goodman handle and light holders with a 1/4"-20 thread will give you the option to mount the lights just about anywhere.
A wide beam M700 is available under "M700i". Instead of a 15-degree narrow beam it offers a 75-degree wide-angle beam. You have the option to mix and match the beam angles based on your personal preference. Being so small, the M700t can be mounted on helmets, spear guns, masks, and just about anything that you can think of.

Frequently Asked Questions
What do lumens mean on a dive light?
Lumens measure the total light output, but they say nothing about how that light is shaped, so a tight narrow beam can look far brighter at distance than a higher-lumen wide beam. Beam angle, color temperature, and water clarity affect what you actually see as much as the lumen figure does. Use lumens to compare lights of a similar beam type rather than as a single score of quality.
What is the difference between a primary and a backup dive light?
A primary light is your main light, usually brighter, larger, and with a longer burn time, while a backup is a small, simple light carried in case the primary fails. Any dive where you need a light to exit safely, such as a night dive, calls for carrying at least one backup. Backups are chosen for reliability and simplicity rather than for maximum output.
How long will a dive light run on one charge?
Burn time and brightness trade directly against each other, so the same battery run at a lower power setting lasts substantially longer. Manufacturers usually quote burn time at each power level, and many lights automatically step down output as the battery drains or the head heats up. Treat quoted figures as fresh-battery, ideal-condition numbers and plan for more burn time than your dive actually needs.
How do I care for the o-rings on a dive light?
The o-rings sealing the battery compartment are what keep the light from flooding, so inspect them for grit, hair, and nicks every time you open it, and wipe the sealing surfaces clean. Lubricate lightly with the grease type the manufacturer specifies, using a thin film rather than a heavy coat, because excess grease attracts sand. Replace o-rings when they look flattened, cracked, or dry, and do not over-tighten the cap in the hope of sealing a bad o-ring.
Can I fly with dive light batteries?
Lithium batteries are subject to airline and regulatory limits that vary by cell chemistry, watt-hour rating, and whether the cells are installed or loose. As a general rule lithium cells travel in carry-on baggage rather than checked baggage, with terminals protected against short circuit, but you must confirm your airline's current policy and any local rules before you fly. Carrying the manufacturer's battery specification sheet helps if you are questioned at screening.
How should I store and maintain a dive light between trips?
Rinse it in fresh water after each dive day and work the switch while it is submerged so salt does not crystallize inside it, then dry it before opening. For storage, remove or charge the batteries as the manual directs, and leave the cap loose so the o-ring does not take a permanent set. Never store a light with corroded or leaking cells inside it.
Should I turn a dive light on before I get in the water?
Test it briefly as part of your pre-dive check, but do not leave a powerful light running in air, because many are designed to shed heat into the water and can overheat on the surface. Check the manual, as some lights have thermal protection that dims or shuts them down when they are dry. Testing before you gear up is far better than discovering a dead light at depth.
