Sola Nightsea UV Light
The Light and Motion Sola Nightsea is similar to a blacklight that illuminates underwater fluorescents to make things glow unlike you've ever seen before. Nightsea emits a special variable angle blue beam that is used to cause certain marine life and organisms to emit a visible glow. Special mask and camera filters are required to make the fluorescence visible. The blue light emitted by the Nightsea results in a much more intense fluorescent response than traditional Ultraviolet (UV).
The Sola Nightsea uses the same factory sealed battery compartment and smart dashboard controls as the dive, photo and video ranges but emit the special blue light rather than white. The light can be changed between three different output levels measured in Radiant Flux (mW), 3000 flood / 1700 spot, 1500 flood / 850 spot and 750 flood / 425 spot as well as between a 60 degree flood and 12 degree spot beam. The Sola Nightsea also features a very useful filter lens that is fitted over the torch lens to convert the blue light back to white light for navigation. The filter lens can be fitted and removed as necessary.
The built in lithium-ion battery is charged using an external plug that connects to ports on the back of the housing. Charging takes approximately two and a half hours and a full charge lasts approximately:
The smart dashboard provides full control over the output levels using a magnetic slider to switch levels, beam angle and turn the light on and off. The three LEDs at the top of the slider provide status feedback of battery level and current power level selected. The slider can be locked by returning to the centre and turning 90 degrees.
The Nightsea is supplied with mains charger, lens filter, ballistic handle and manuals. As with other Light and Motion lights, the Nightsea is compatible with other mounting options for attachment to photo and video rigs.
- 3000mW flood and 1700mW spot output certified to the FL-1 Standard
- Colored battery and mode indicator lights make it easy to manage battery life to maximize use.
- Attached Phosphor Cover converts blue light to white for navigation and general use.
- Includes nightsea mask filter and standard ballistic cordura hand mount

Light and Motion Sola Nightsea UV Light - Features
|Battery Level Indicator|
?Whether the torch has a built-in battery level indicator.
?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
|12 to 60|
?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.
|Burn Time at Max (Mins)|
?The length of time that the torch will provide light at 100% power.
|Lumens at Max|
?The torch lumen output at 100% power.
|Maximum Depth (m)|
?The maximum depth that the torch has been rated to by the manufacturer
?Whether the torch is supplied with a rechargeable battery and charger or whether it runs off standard batteries.
?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.
|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.
?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.
?Whether the torch offers multiple power levels other than the standard on and off.
