Finn Sub

3600 Short Light

£607.00 RRP £715.00 In 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
Whether the torch has a built-in battery level indicator. 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 dives Close.
Bulb Type
Advances in bulb technology has created a number of different options for light source, each with their own advantages and disadvantage:

Halogen & Xenon - The oldest technology, a spring like filament that glows white hot then electricity is passed through it, producing light. Later filament bulbs are filled with Xenon to produce a more intense and brighter light.

HID - High Intensity Discharge lights have a capsule of gas instead of the tungsten filament. HID bulbs typically produce more light at a lower temperature and are significantly more efficient as they produce a lot less heat and require less energy to maintain the light level.

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.
Burn Time at Max (Mins)
The length of time that the torch will provide light at 100% power. Close.
Lumens at Max
The torch lumen output at 100% power. Close.
Maximum Depth (m)
The maximum depth that the torch has been rated to by the manufacturer Close.
Whether the torch is supplied with a rechargeable battery and charger or whether it runs off standard batteries. Close.
Switch Type
There are a number of different switch types available.

Manual switches physically complete the circuit by moving the contacts inside the torch. This type of switch passes through the body of the torch which adds a possible point of failure but are signifcantly cheaper to produce.

Twist caps 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 when turn off the torch there is a very small risk that the torch could flood

Magnetic switches are becoming more popular as they do not need to pass through the body of the torch and instead use magnets to operate the torch. This eliminates any potential flood risks resulting from a failing switch.

Kinetic torches are controlled by motion and are the most water tight solution. Close.
Twist Collar
Torch Body Material
The material that the main body of the torch is made from.

Plastic will produce a typically lighter torch but a torch made of aluminium will be stronger and more robust due to the density of the material. 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 see. Close.
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
