Sea Dragon 4500 Pro Video Light
The SeaLife Sea Dragon 4500 Pro Video Light is a powerful photo/video light with an even beam to illuminate the scene in an even light to bring out colours and shadows underwater. If you're taking pictures with a flash a built in sensor detects a flash and deactivates the light for a second so you don't get unwanted light or shadows before turning back on.
Powerful 4500 lumen LED light. Latest COB LED array technology
96 (+/-1) CRI (color rendering index) that mimics natural sunlight
Auto Bright mode adjusts from 10% to 100% (450 to 4500 lumens) to preserve your eye’s natural night vision and extends battery life
Auto Flash Detect mode. Light turns off for 1 second when detecting external flash
One button control for easy operation. One button to power light on/off and select brightness
Five brightness modes: 100%, 75%, 50%, 25% and Auto mode (10% to 100%)
Hidden emergency signal mode. 1 sec blink interval and SOS Morse code. Push and hold power button for 4 seconds to activate (from off state)
4 hour burn time at 1000 lumens and constant brightness (1 hour burn time at full power)
Easy to expand with YS or Flex-Connect™ mounting system of arms, grips, trays and adapters.
Quick-release button to detach light and aim in crevices and hard to reach areas
120° wide beam angle evenly illuminates the subject with no hot spots.
Depth tested to 330ft (100m)
Corrosion-proof metal light head for heat dispersion and durability
Removable 50W Li-Ion battery w/ charger and international plug adapters included

*CRI is a measure of a light source's ability to show object colors "realistically" or "naturally" compared to daylight, which has a CRI of 100 and represents the maximum value.
The beam angles for the Sea Dragon lights are shown as the true, tested “in-air” (above water) beam angle. Underwater, due to light refraction, the angle tightens to approximately 33% less.
SeaLife Sea Dragon 4500 Pro Video 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
?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.
|x1 COB LED|
|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.
