5. Light and Motion SOLA Dive 1200 F/S

Underwater photographers frequently employ red filters to try to achieve this effect, but red filters are ineffective since they still allow too much light through. The Motion Sola only utilizes 300 lumens in red light mode, creating a narrow powerful beam of red light that is undetectable by many aquatic animals.

The red light mode is one of the nicest and most important aspects of the Motion Sola 1200 light. It’s ideal for filming marine life that would normally terrified and hide by a standard white light. Because some underwater life cannot sense red light, it works perfectly to allow photographers to make a video or picture these elusive species.

It does an excellent job of supplying the light needed to obtain crisp and lit underwater photos. The light itself has a depth rating of up to 330 feet, so it’ll suffice for most dive expeditions. A 60-degree angle of beam is also available on the Motion Sola 1200.

It features three power settings allowing you to customize the light brightness. The white light output is 1200 lumens in high mode, 600 lumens in medium mode, and 300 lumens in low mode.

It weighs only 8.75 ounces and is made of aluminum and tempered glass.

The dive light is simple to operate and the ability to wear it on your hand allows you to accomplish more underwater. The light offers three brightness settings.

how much light

And now let’s see what characteristics of underwater dive lights should be considered when choosing the right one

Types of Dive Lights:

light monkey
  • Primary Light

These underwater flashlights should be larger and have enough battery power to last the entire dive whether used during the day or at night. Dive lights must got rechargeable battery for better usage. Also would be good if underwater flashlights got a bright narrow beam and a pistol-style grip or other easy-to-hold features.

  • Secondary or Backup Light

This should fit in your BC pocket and is likely to be less expensive in your own gear.

  • Photo/Video Light

These versions should have a wider and brighter beam and they are designed to be put a top on camera.

Lumen

underwater kinetics

Lumens measure the amount of light emitted per unit time. Of course, the higher the lumens, the better the view.

The number is often exaggerated by manufacturers to drive sales.

When looking for an underwater flashlight, consider whether you need it for video illumination, which requires a wider beam angle, or just for illuminating crevices, holes, caves, which need a smaller angle of beam (it can cover a range from 12 to 75 degrees).

LUX

night dives

A LUX value is used to determine how bright a surface is at a given distance and this is very important.

This means the underwater flashlights have a strong scattering effect if its lux value is low and it has a high lumen count. Video lights are best recorded using this technique.

If you want to illuminate small gaps, crevices and caves during snorkeling, an underwater flashlight with a high lux value and a large amount of lumen is the best.

Light output over 2000 lumens in LED underwater dive lights are considered comparable to daylight.

Power

wide light

For underwater dive lights to have good effect it must have at least 800 lumens.

Type of lightbulb:

  • LED

Bulbs have a longer battery life than xenon lamps since they are brighter, more efficient, sturdy and long-lasting. They do, however, provide a colder, bluer tint that photographers prefer to avoid.

  • XENON

These the incandescent dive lights were the only ones accessible 20-25 years ago for diving. They are the cheapest, but they also have the lowest lumen output. They are using a lots of power.From this reason the battery life is short.The photographers like the more natural, softer and less blue look that xenon dive lights produce.For example LED or HID lighting.

  • HID bulb

It’s a type of LED light that is no longer in use since it is inefficient.

Working Time

night dives

As the underwater torch shines brighter the shorter the working time will be. The maximum charging capacity of the battery and the number and type of LEDs also play a role in this.

Material and Fabrication

Marine grade aluminum is a better choice for underwater dive lights. Plastic does not dissipate heat as well as aluminum. As a result LED lamps last longer without getting too hot.

Choosing a dive lights with a glass front is also more desirable than one with a plastic one. Over time, your underwater flashlight will lose brightness due to scratched plastic.

Size and usability

night dives

It is important that the underwater flashlight’s controls and buttons are easily accessible, even when wearing gloves. It is also advisable to keep an underwater flashlight with good batteries and a few LED lights in your BCD pocket if not needed to keep it on hand. Make sure that underwater flashlights are easy to use.

Batteries

Typically the batteries included with the torch are cheap and don’t last very long. I suggest buying some proper batteries right away from the top.

To reduce the environmental impact of batteries I recommend using rechargeable batteries.

Make sure that the charger you use for these batteries is appropriate.

Waterproof

dive buddy

You can tell how waterproof the torch is by its IPX rating. The classification goes from IPX0 to IPX9. A higher IPX rating means better protection from water under pressure.

However, manufacturers do not always indicate this characteristic, instead they mention the working depth of the flashlight.
