Finn Sub

3600 Short Light

£643.00 RRP £715.00 Out Of Stock

Brand: Finn Sub

Model: 3600 Short Light

SKU: 65247

Please note: This item cannot be shipped outside the United Kingdom

The Finn Light 3600 Short is a small but powerful primary torch with a tight 10° beam and 3600 lumens to cut through murky waters. One hour burn time at full power and 12hrs at 10% you have full control of the torch and can conserve battery power when you don't need it. Attached to a handle you can still use your hands while holding the torch securely and the small size make it convenient when you're not using it.


The 3600 Short has all the benefits of it's predescesors including a long run time, a bulb that produces little heat so you can use the light on the surface when on 10% and three power settings give you control.


Tight Beam Angle
Most of the light is focused into a tight 10° beam to cut through the water and is great for signaling but a halo around that will illuminate the dive site without blinding your buddy.


Heat treated Aluminium Alloy is both light and strong as well as corrosion resistant. Anodized with a hard Eloxal Coating that acts as a shield to the usual abrasion a torch can go through.
Borosilicate Glass protects the front of the light from changes in temperature and is hard itself.

Finn Sub 3600 Short Light - Features

FeatureProduct Specification
Battery Level Indicator
Some torches come fitted with a battery level indicator so you know how much power you have left. Most are a colour coded light that gives you a rough idea of how much power you have left but some will estimate your remaining time in minutes.Close.
Torches require a power source and either have a built in rechargeable battery, removable rechargeable battery or a standard size disposable battery.Close.
Beam Angle
Narrow beams are great for cutting through low visibility, helping a diver to see further without creating backscatter from the light reflecting off particles in the water. Narrow beams are able to penetrate further and are ideal for looking in openings or under rocks Wide angle beams are best for good visibility and spread the light over a larger area. A larger lit area means that the torch does not have to be continuous moved and are particularly effective on night divesClose.
Bulb Type
Advances in bulb technology has created a number of different options for light source, each with their own advantages and disadvantage but most today are LEDs. LED - unlike ordinary incandescent bulbs, Light Emitting Diodes don't have a filament that will burn out, and they don't get especially hot. They are illuminated solely by the movement of electrons in a semiconductor material. An LED is a lot more efficient than a filament bulb and also a lot more durable than both filament and HID bulbs.Close.
If measured, the buoyancy of the torch is how positive or negatively buoyant the torch is in water. Usually measured in fresh water, knowing the buoyancy of your torch can help with your overall buoyancy and weighting so you can be better neutrally buoyant when diving. Measured in GramsClose.
Max Burn Time (mins)
The length of time that the torch will provide light at 100% powerClose.
Max Depth (m)
The maximum depth that the torch has been rated to by the manufacturerClose.
Max Output (lumens)
The maximum brightness of light the torch can produce at its highest setting.Close.
Switch Type
There are a number of different switch types available. Push buttons require the diver to depress a button to activate the torch and change power settings. Many use a magnet on the outside of the body so that no part goes through the body itself but some still do with seals to prevent water ingress. Twist ends, collars and heads are very common. The diver simply twists the bottom cap or head unit to complete or break the circuit. Twist caps usually have a double o-ring to protect the battery and electronics from damage. The disadvantage of a twist cap is that if the diver was to unscrew the cap too much, there is a risk that the torch could flood. The O-Rings also wear with use so prolonged use can result in flooding. Kinetic torches are controlled by motion and are the most water tight solution.Close.
Twist Collar
Torch Material(s)
Torches are usually either a polymer or anodised aluminium for corrosion resistance. Plastic parts are cheaper but more fragile to damage.Close.
Anodised Aluminium
Torch Type
Whether the entire torch (including batteries) is held in the hand or whether the light unit is connected via an umbilical cable to a seperate battery unit for extra capacity and burntime. Photo / Video Lights have an even beam that floods the scene with light with no hard edges or hotspots so it doesn't look odd or stand out in your pictures. Ultra Violet Lights use a specific wavelength of blue light, not usually Ultra Violet, that excite certain parts of animals that cause them to glow and fluoresce showing unusual patterns that the naked eye cannot seeClose.
Variable Output
Whether the torch offers multiple power levels other than the standard on and off.Close.

I have used the Finn Sub 3600 Short in...

I have used the Finn Sub 3600 Short in the English channel 4 times so far. My buddy has the 3600 with the canister, and I''d say the short is as bright or maybe even a little better. The hand grips take a little getting used to, but is fine with 5mm
