A dive light is any light source carried by an underwater diver to illuminate his route, especially at night. Primarily, self-contained lights are used by divers, while in few cases, lights powered by cable supply are used.
Dive lights are mainly used at night or during cave dives when little or no natural light source can find its way. Dive lights help in providing lights underwater navigation, safety, and seeing the actual color of objects.
How to choose a dive light
One of the essential Scuba diving equipment for your safety and enjoyment should always be with you whether you’re diving during daytime or nighttime.
You might be wondering, do you need a dive light if you’re starting diving? Yes, you need a dive light, beginner divers go as far as 50 to 130 feet, and at just 30 feet, everything loses its color and turn to shades of gray and blue – and that’s not perfect if you are in the sea for the unique visual experience of seeing underwater.
A good dive light is your best friend during dives, as it will help you reveal your way through and guide you through darker and deeper waters. If you’re looking to purchase a dive light that you will use for your next diving, here are some factors to note:
What activities are you willing to engage in?
When choosing a dive light, the first thing to ask yourself is what activities you are willing to engage in, as there are different types of dive lights, so you need to select the best for your actions. If you’re going on spearfishing, choose a light that can be mounted on your weapon or your head to have your hands free to operate your tools and weapon. A sizeable primary light will be the best if you’re exploring underwater caves and significant shipwrecks. Oh, note a sizeable primary light if you’re visiting the wreck of the Titanic (winks).
The Beam angle of the dive light
Another crucial factor to note when choosing a dive light is its beam angle. A narrow beam angle is what you will need for illuminating specific spots, such as when you need to observe a water plant, a small rock, or an underwater crevice. A narrower light is also the perfect option for hazy, low visibility waters.
A wider beam angle is needed for night driving as it provides maximum visibility of the surroundings and keeps you alert of dangers.
How deep are you willing to go
A good thing to note when choosing a dive light is the duration of your dive as the longer your dive light’s power duration is, the more reliable it is during long drives. This highly depends on the kind of material your underwater light source was made from whether it is high-intensity discharge, light-emitting diode, or incandescent.
Mostly, LEDs and HIDs offer more powerful lights and last for longer durations. LEDs however are more popular as they are more energy-efficient, durable, and more robust than HIDs.
Incandescents are usually less powerful and less expensive than LEDs and HIDs, and also have a shorter battery lifespan. But you might be wondering, Why do most divers still use Xenon despite their short battery span? The main reason is that incandescents give off warmer colors which can make sea creatures and plants look more appealing in pictures and videos.
Just be alerted that, the deeper you go, the darker it gets, which is why you need to get a powerful light source with a long battery span if you are going on deep dives.
Note your budget
The last but most important thing to note when choosing an underwater light source is your budget. Dive lights with powerful bulbs and a longer battery span are more expensive. Because dive lights become your main source of safety in deep water, investing in them becomes worthy in the long run. This is particularly why you are required to choose an LED light, as it provides more power than incandescents and lasts longer than HIDs.
Again, if you’re buying multiple light sources to rig them together for photography and video sources, it’s better to buy a single good one as the affordable ones can rack up a bill if they’re bought in multiples.
Also, note investing in rechargeable batteries than cheap disposable ones that you have to be changing frequently. In a nutshell, choose a dive light that favors your budget while favoring you.
Types of dive lights
After knowing the factors to note when choosing a dive light, the next thing to look at is the types of dive light to choose the one that suits you best. Below are some types of dive lights:
- Primary dive light
Primary dive lights are handheld light sources that are large, bright, and designed for both nighttime and daytime usage in hazy water bodies. It usually comes armed with a pistol or lantern grip and divers usually find this type of light more comfortable compared to stick lights. It has a wide coverage, and its power is focused in the center beam making it to be able to penetrate through turbid water bodies without requiring an additional light source.
Primary dive lights are very durable as they can last for up to ten years, which makes them very expensive. They offer three choices of bulbs – the long-lasting LED light that offers more light and power than the older halogens comes at an affordable price, the HID bulbs produce power five times than the halogen bulbs comes at a pretty expensive price and the cheap halogen bulbs that give off the warm traditional light. Primary dive Lights can use either disposable batteries or rechargeable batteries.
If you’re going on night diving or deep diving, a primary dive light is the perfect source of underwater light for you.
- Secondary dive lights
Unlike primary dive lights, secondary dive lights are smaller handheld light sources that can be used for extra illumination during daytime diving. However, some divers use a secondary dive light as a backup in case your primary light source stops abruptly. These types of light sources offer a narrower beam light as such they can be used for illuminating specific spots in waters.
Secondary dive lights are very smaller and compact and can be inserted into the pockets of your buoyancy compensator, they also offer a narrow beam light compared to other underwater light sources due to their small size.
For shallow daytime diving, take a secondary dive light In case your primary dive light stops.
- Canister dive light
Canister dive lights are mostly used by technical divers and deepwater divers exploring shipwrecks and caves. It is also known as a canister light and comes with a canister containing a battery pack that connects to the light bulb using a long coarse power wire. This makes the battery larger, thus being able to contain more power and in turn, gives off a brighter and wider beam of light more than primary dive lights.
The bulb of a canister dive light is separate from the apparatus, thus giving you the chance to attach the bulb to your wrist or waist. For deep water diving and explorations, a canister dive light is the best source of light for you.
- Marker dive lights
If you’re in murky low visibility water and you need to keep visible to your diving team, note getting a marker dive light. This will help keep you visible to your team especially if your secondary or primary dive light is pointing away from them.
The lumen rating of marker dive lights doesn’t matter much, if you’re going on a long burn time, a nondisposable lumen like LED strobes or flares are recommended. These came in different designs and colors and are usually attached to your snorkel or your tank valve.
Avoid glow sticks as they are not environment friendly and can only be used once.
- Mounted dive lights
Mounted dive lights are for divers that want their hands free during explorations, spearfishing, or treasure hunting. It is usually mounted on its head like the ones hikers use, sometimes, it is mounted on the wrist or top of the hand.
Note using mounted dive lights with disposable batteries as they last longer and can be used once you need to as far as you have got a fresh battery pack available. However, using disposable batteries will cost you a lot of money in the long run and it is not eco-friendly.
Mounted dive lights are very small and compact, they’re a good light source during cave and shipwreck explorations, especially if you get a good one that gives off a strong beam of light.
- Photography and Video dive lights
Photography dive lights are types of dive lights that emit a flash of light each time an image is taken. A video dive light on the other hand offers a more wide and good flood of light thereby exposing a scene properly, unlike a primary dive light that has concentrated on the middle.
Photography and video dive lights are mostly adjustable to give you a chance to properly expose your shots and videos.

Buying Guide Questions
Below we shall take a look at some frequently asked questions by dive light buyers about lumens and how to choose a dive light.
How many lumens do I need for a dive light?
This highly depends on your plans and how deep you want to go, a dive light with an average of 200 or more lumen output is okay for any recreational diving.
For an exploration of shipwrecks and caves, a dive light with a higher number of lumens is required.
How do I choose a dive light?
There are many factors to note when choosing a dive light, they include; the activities you are willing to engage in, how deep you are going to dive, why are you diving and how much do you have.
Your activities will determine the kind of light you’re going to choose, as a light for recreational diving might not be good for exploration diving. The depth you’re intending to go is also a crucial factor to note, as most dive lights have the maximum depth of water they can light. For more about how to choose a dive light, check the beginning of this article.
How deep can you dive without dying?
A human being can dive to a long-distance without dying. The average human bone crushes at about 11159 kilograms per square inch. This means a human being can dive up to 35.5 kilometers before the bone crushes. And this point is three times as deep as the deepest ocean.
How bright is 1000 lumens?
1000 lumens is very bright, that is, it’s bright enough to let you see items at a very far distance from where you are. Most dive lights feature lenses to focus light into a range of about 150 to 200 meters
How many lumens do I need?
Generally, for diving, a dive light with a lumen output of 200 and above will work perfectly for any kind of diving. The exact number of lumens that you will need depends on the kind of diving you’re going and how deep you intend to go
How many lumens are HID?
HIDs generally have about 3,500 lumens which are about three times that of a halogen lamp.
How deep do navy seals dive?
Navy seals don’t have a specific depth that they dive into. Rather dive only as deep as they are required to. Commonly, they don’t require being in deep water for their diving, but during their training, they are taught to dive as deep as 100 to 300 feet.
How far will 5000 lumens shine?
5,000 is a large amount of lumen and it is capable of covering a range of up to 250 square feet.
Is 3000 Lumen too bright?
This depends on the size of your room. 3000 lumens can be used to give a large room a bright light. If your room is small or it’s a bedroom it’s not advisable to use a 3000 lumen as it might be too bright.
Dive lights are extremely important as they help you in having a good view of the water, they also protect you from prey and keep you visible to your dive team. Having a good dive light will help you a lot in the success of your diving, with the above guide and review, we’re sure you have a good guide in choosing a dive light.
