If you are an avid Underwater Videographer you know you’ll need a bright underwater Video light to get the most out of your footage.
In this guide we’ll explain what you need to take care of and important factors before buying your underwater video light.
Why do you need an underwater video light?
As you go deeper Water becomes darker due to less sunlight reaching the lower depth as light gets reflected by particles.
You are also loosing colors the deeper you go. That has to do with the wave length of the different spectral colors. Red disappears first and blue is last to disappear…now you also know why water is blue! or isn’t it? 😉
Spectral colors with long wavelength such as red are absorbed much faster. One third of the red color is absorbed after just 1m of depth.
So for underwater videographer it’s important to have a proper underwater video light to get all colors back artificially.
You can use certain filters but you can not replace a proper underwater video light.
With light its as with most other products as well, the higher the price the better the components built in. Especially in torches or underwater video lights manufactures often lie about lumen and how bright the light is.
What is Lumen
The lumen (Latin for light, lamp) is the SI unit of luminous flux. So it indicates how much light a lamp emits per unit of time.
To determine the lumen you will need in a Scuba Diving torch is kind of easy; the more the better. However the lumen information on a description of a flashlight is important, but manufacturers often use them as a marketing tool and exaggerate this number.
So sometimes it is better to rather look for built quality and materials used and researching other pages to determine different lumen information of the torch you are looking to buy.
Depending if you need a torch for illuminating a video which needs a wider flood angle or just for illuminating crevices, holes and caves which will need a a smaller angle of beam light. Average beam angle range between 12 to 75 degrees. For underwater video lights it is most important to have a very wide angle of light beam everything above 100° degree is suitable. this is to duplicate the suns light.
Imagine you have a small beam torch you would only illuminate a small part of your object.
What is Lux? Beam range
The lumen should not be confused with the lux. Lux is the unit of illuminance that indicates how much light per unit of time per unit of area.
As far as the torch distance range is concerned, the LUX number is a decisive value. This determines the luminosity for a specified distance.
If the Torch has a low LUX value and at the same time has a high number of lumen, this means that the torch emits light more broadly, i. H. has a strong scattering effect (flooder torch). These kind of scuba diving torches are particularly suitable for underwater Video lightning.
If the torch has a high LUX value with a high number of lumen at the same time, then one speaks of so-called thrower torches. These are characterized by the fact that they bundle the light beam very strongly and thus achieve a high distance beam range. They are particularly suitable for recognizing details over long distances and are better for scuba diving if you want to illuminate the small spaces, crevices and caves.
What type of LED is used in torches?
Virtually all scuba diving torches made today use an XM-L LED. This LED produces a full-flood beam, with less throw than the XP-G. Total lumen output for the original XM-L peaked at near 700. Differences in the T6 and U2 flux bins include higher brightness. All LED scuba diving torches with a light output of over 2000 lumen fall into the category of comparing it with daylight.
The light beam is always generated with several high-performance LEDs such as CREE XP-L V6, CREE XM-L2 or CREE XHP70.
An average 100 lumen torch is able to provide around 5 -10 hours runtime using 2x AA battery. This amount of lumen is technically enough for urban and suburban use but probably not for scuba diving. In Scuba Diving you’ll need at least 700+ Lumen to get anything out of your purchase.
You should have a look at the actual working time of a scuba diving torch. The maximum working time is always given for the lowest set light intensity.
This also depends on the Type of Battery the maximum charge capacity of the battery as well as the number of LEDs and the LED type.
Do LED underwater video lights get hot? 🔥
The underwater video lights produce heat when on, and the heat comes from the associated core of the LED bulb. The greater the power consumption of the LED light and or the more LED’s, the more heat appears. Most of them have an overheating switch built in but underwater due to the good heat dissipation of water the torches usually never overheat. Depending on the power of your LED’s this might be a different story if you turn them on and use it as a normal torch on land.
Material and fabrication
Look for Marine grade Aluminum in underwater video lights, it not only last longer than plastic but it also dissipates the heat much better which also extends the life of the LED bulb as it doesn’t become to hot.
Size and usability
In Scuba Diving it’s always important not to have to big appliances. However an underwater video light with good Batteries and a few good LED’s should fit in your BCD Pocket to store it away if not needed and not dangling around. The flashlight should be easy and intuitive to use.
Batteries and rechargeable batteries
Under no circumstances should batteries with too low or too high voltage or amperage be used, otherwise the LED’s could be damaged and also not being able to use up their maximum illumination capacity.
Many different Batteries are used in scuba diving torches. Make sure you not only have the correct Battery but also the correct charger for your rechargeable Batteries.
Rechargeable Batteries are the “better” environmentally friendlier Batteries due to less toxic rubbish.
Care and cleaning
After diving in salt water, fresh water or in a swimming pool, you should always rinse your underwater video lights with fresh water and then let it dry. You should also press the buttons while washing so that the remaining salt water or dirt is rinsed out. To store the torch take out the Batteries if possible to avoid leaking or low discharge.
