Top 10 Best Dive Lights Reviews

1 ThorFire Scuba Diving Flashlight – Best Dive Lights for Cave Diving

Those in search of a top quality diving flashlight should take a close look at this first entry on the list of the best dive lights. Built by ThorFire, this is one of the best cave diving dive lights.

How bright is it?

The 3 CREE XPL LEDs pump out 2000 lumens. This equates to a throw of 656 feet., which will be more than enough for the average diver. The dive light is rated to a depth of 230 feet. (70m), and that covers most recreational dives quite easily.

Will it last?

Crafted from aircraft-grade aluminum with double O-rings, this flashlight holds an IPX8 waterproof rating. The magnetic control rotary switch offers complete control, no matter the conditions you’re diving in.

How long will the illumination last?

This diving flashlight runs off 4x 18650 3.7v batteries, providing about an hour’s worth of use. That’s long enough to ensure you’ll likely run out of air long before your flashlight runs out of charge. It should be noted that the batteries are sold separately.

ThorFire Scuba Diving Flashlight

Our rating:3.9 out of 5 stars (3.9 / 5)


  • 2000 lumen output.
  • Depth rated to 230 feet.
  • Aircraft-grade aluminum.


  • Doesn’t have the best seal, so check it before heading out.

2 OrcaTorch D520 Diving Flashlight – Best Dive Lights for Night Diving

Diving is one of the most dangerous, yet is still one of the most enjoyable sporting activities there out there. The danger aspect is what leads most experienced divers to use backups. This next entry on our list of the best night diving dive lights makes for the perfect backup dive light.

A perfect back up, or one of the best dive lights for beginners.

The super bright CREE XM-L2 provides neutral white shine of 1000 lumens. The 5000K LED color temperature provides color rendition that you’ll appreciate whether you’re taking photos or just enjoying the day.

What’s the depth rating?

The OrcaTorch is rated down to 150 meters, which covers recreational depths with some wiggle room left over. The 4mm thickened tempered glass and triple waterproof O-rings keep your underwater torch secured from water damage. Professional style rotary switch ensures easy control of the light in any condition.

What about the battery?

The D520 dive light is compatible with a range of battery options, making this one of the best dive lights for murky waters. Simply load up a single 18560 battery, or two CR123A or 16340 batteries. We like this, as it means no matter where in the world you are diving, you should be able to find batteries.

OrcaTorch D520 Diving Flashlight

Our rating:4.7 out of 5 stars (4.7 / 5)


  • 1000 lumen output.
  • Depth rated to 150 meters.
  • Compatible with a range of battery options.


  • Not the brightest torch, but good quality for the price.

3 ScubaPro Nova 200 Dive Light

One of the most recognizable brands in the scuba diving world is ScubaPro. Their Nova 200 dive light offers a great option for those looking for an option that will easily fit in a BCD pocket.

It’s compact and lightweight enough to meet every diver’s needs…

Composed of lightweight aluminum, this dive light gives off 200 lumens. This isn’t nearly as much illumination offered as with the two lights we’ve already reviewed. For this reason, we would recommend this light as a backup. It’s certainly not the best dive light for the money.

What about battery life?

Running off three AAA Alkaline batteries, this dive light will deliver up to 8 hours of illumination. Plus, the impact-resistant LEDs will not break if you accidentally drop the light on land or bump into something below. The push-button switch and wrist lanyard with sliding barrel lock help keep you in complete control of the light beam.

What color light does it provide?

For maximum visibility and more accurate colors, the flashlight uses white LEDs. This allows the light to travel farther underwater for a better and safer experience.

ScubaPro Nova 200 Dive Light

Our rating:3.6 out of 5 stars (3.6 / 5)


  • Doesn’t need special batteries.
  • Compact and lightweight.
  • Impact resistant.


  • Not the brightest illumination.

4 Underwater Kinetics SL4 Dive Light – Best Dive Lights for GoPro Users

The next flashlight built for diving on our list of quality dive lights is crafted by Underwater Kinetics. The SL4 is designed as a secondary diver light and is meant as a backup rather than a primary source of light.

However, it is one of the best GoPro dive lights…

Built tough as any dive light should be, the LEDs on this flashlight are durable. They won’t break if you drop it, or knock in on something when underwater. The single-handed thumb switch is convenient and practical for one handed use.

How much light shines from this dive light?

While it’s brighter than some, this still isn’t the brightest dive light we reviewed. Offering 400 lumens, this flashlight will offer around 10 hours of illumination. The narrow beam of light cuts through the water for better visibility in murky waters.

Underwater Kinetics SL4 Dive Light

Our rating:4.1 out of 5 stars (4.1 / 5)


  • Narrow light beam.
  • 400 lumen output.
  • Long battery life.


  • Not the brightest option available.

5 Light and Motion Sola Dive Light

If you’re looking for one of the best scuba lights on the market, then this next entry is likely just what you’re looking for. Designed as a primary scuba light, this option has considerably more features than others reviewed here. It is also the most expensive option on this list of the best dive lights.

How bright is it?

There’s a total of five light options. The first high beam mode offers 1200 lumens in a flood pattern. The lower beam mode provides 500 lumens in a tighter spotlight fashion. Both of these offer three further power settings.

This alone makes this the best for photography, but what else sets it apart?

The factory sealed housing guarantees no flooding will ruin your dive. The rechargeable Li-ion battery will provide 270 minutes with the low power setting. So, you’ll be able to extend your dive right up to the maximum without worrying about exiting in the dark.

This could well be the best dive light for photographers, cave divers, or those who enjoy night dives. Light and Motion certainly have produced a top end waterproof flashlight. The Sola Dive Light even provides 60 degrees of even light in the floodlight setting, for illumination of your entire field of view.

Light and Motion Sola Dive Light

Our rating:4.5 out of 5 stars (4.5 / 5)


  • Rechargeable battery.
  • 1200 and 500 lumen output settings.
  • Wide flood beam or spotlight illumination.


  • The most expensive option reviewed here.

6 Underwater Kinetics UK Light Cannon eLED Scuba Diving Light – Best Dive Lights for Camera Users

Our list of the highest quality dive lights now looks to another option from Underwater Kinetics. The UK Light Cannon can be used with a pistol or lantern style grips. This makes this one of the best camera dive lights.

How bright is it?

Producing a massive 2100 lumens, this dive light offers a full and half power mode. This means you can opt for the power saving lower illumination mode, or go full power for ultimate brightness. The high color temperature provides light in the same color and shade as sunlight, for true colors underwater.

What about the durability?

There is a heavy rubber boot that protects the front lens from drops and knocks. The non-corroding ABS and polycarbonate plastic construction will stand up to tough use. Disposable alkaline batteries can be used for power, or you can employ a rechargeable UK NiClad upgrade kit.

Underwater Kinetics UK Light Cannon eLED Scuba Diving Light

Our rating:5 out of 5 stars (5 / 5)


  • 2100 lumen output.
  • Pistol or lantern style grips.
  • Tough, durable materials.


  • Not the most expensive but more pricey than many other options.

7 Ikelite Gamma LED Dive Light

One of the most compact options that we reviewed when looking for the best dive light is produced by Ikelite. The Gamma dive light weighs only 4 ounces. You’ll easily be able to slip this flashlight into your BCD pockets and forget it’s there until it’s needed.

Can something so small provide proper illumination?

The light shot from this unit may only offer 350 lumens, but they are configured into a tight 10° beam. With a color temperature of 6500K, it will feel like you have a much stronger dive light than you do. This all runs for up to 10 hours on two CR123 batteries.

Is it durable?

The aircraft-grade aluminum and precision machining come together for an ergonomic and non-slip grip. With no grooves or texture to get caught, this dive light was designed to easily slip in and out of your pocket. The switch is located on the tail, and the touch button can be used for momentary or continuous illumination.

How deep can we take the light?

This scuba light is rated to 120 meters (400 feet). This more than covers recreational diving limits and makes this a great backup dive light.

Ikelite Gamma LED Dive Light

Our rating:4 out of 5 stars (4 / 5)


  • 350 lumen output.
  • Rated to a depth of 120 meters (400 feet).
  • Illuminates in a right 10° beam.


  • CR123 batteries can be difficult to find in some diving locations.

8 Dorcy Submersible Dive LED Flashlight – Best Dive Lights for Beginners

This may be one of the cheapest dive lights available on the market today. Produced by Dorcy, the Submersible dive light may not be the top choice of expert divers due to its limitations. Still, it’s a great option for those on a budget.

Is this the best dive light under $100?

Similar to the first couple of lights reviewed on this list, this option has a limited illumination. The light only produces 220 lumens, so it won’t offer top end illumination. But for the price, we think this makes a great entry level dive light.

What’s it composed of?

The anodized aluminum and anti-corrosion, hardened black finish provides the durability that you expect from a dive light. In fact, the flashlight is IPX8 rated to 100 meters (+300 feet).

We think this may be one of the best beginners dive lights. The quality isn’t what you’d want for a long-term dive light. But if you’re starting out or need a backup dive light, this is a good option.

Dorcy Submersible Dive LED Flashlight

Our rating:4 out of 5 stars (4 / 5)


  • Depth rated to 100 meters.
  • Corrosion resistant housing.
  • 220 lumen output.


  • Twist on/off is not a favorite of many divers.
  • Minimal illumination and narrow light beam.

9 Princeton Tec Sector 5 LED Dive Light

Many cave divers prefer a dive light with a pistol grip, as it provides you better control of your light beam. For this reason, Princeton Tec has produced the Sector 5 dive light. While not the most expensive dive light reviewed here, this is certainly a great option for any diver.

How many lumens does it shine?

The 500 lumen output can be triggered in a constant illumination or momentary beam of light. Great for those looking under rocks and in crevices for exciting undersea critters. The trigger style light switch makes it easy to choose with a half pull for a quick illumination or full pull for constant light.

Why have a trigger switch?

Many divers will appreciate this trigger switch on/off. It makes for easy use with gloves on. This makes this a great light for cave divers or those diving in cold areas that require a dry suit and/or diving gloves.

What about the batteries?

Running off four C-Cell batteries, this dive light will provide up to 24 hours of illumination. These batteries also help minimize bulk and weight for a better diving experience.

Princeton Tec Sector 5 LED Dive Light

Our rating:4.1 out of 5 stars (4.1 / 5)


  • 500 lumen output.
  • Trigger switch for easy use with (or without) gloves.
  • Up to 24 hours of light provided.


  • Poor build quality doesn’t offer confidence that the light will last many dives.

10 Light & Motion Sidekick Duo

The final product on our list of high-quality dive lights is the Sidekick Duo made by Light & Motion. Designed to be the brightest and most combat light for GoPro Hero cameras, this flashlight has a very small frame.

Is this the best dive light for GoPro users?

Due to its size and light output, it just might be exactly what you’re looking for to use with your GoPro. There is a 600 lumen floodlight option, and a 400 lumen spot beam option. It’s even manufactured in California and backed by a 2-year guarantee.

What about the run time?

The dual beam mode comes with multiple power settings. This provides between one and six hours of runtime. The factory seal and external charge interface allow for a flood-free design. The dive light is rated to a depth of 60 meters (196 feet).

While we did not experience any issues, some users have noted that their light has flooded. This flooding has reportedly happened within the 60 meter limitation noted by the manufacturer. We suggest checking your seal before heading out for a dive.

Light & Motion Sidekick Duo

Our rating:3.6 out of 5 stars (3.6 / 5)


  • 600 and 400 lumen output options.
  • Multiple power options.
  • Depth rating of 60 meters.


  • Not the best sealed dive light.

Best Dive Lights Buying Guide

Having read through our list of reviews of the best dive lights, you will now have a clear view of the various options available. But how do you know which features are most important to you? To help you with this we have detailed some of the main features to look for…

How bright does the dive light need to be?

As with any other flashlight, it’s generally agreed that brighter is better. The above list of products offer a range of illumination from 200 lumens all the way up to over 2000 lumens. That’s a wide range.

If you’re diving in caves or at night, you’ll want a higher light output. For those diving during the day and looking for a light to use with photography, a lesser output will often suffice.

What beam angle is best for diving?

Similar to the output, as noted, there is a wide range of beam angles available with dive lights. Wider angles are better for caves, and night dives. They offer a wider field of view and help you ensure you’re fully aware of everything around you.Dive Lights

Spotlight options offer a more narrow beam of light. This is better for taking pictures, and looking under rocks and into cracks when underwater. Some dive lights are able to switch between a wide beam and a spotlight option. We think this is best for the primary dive light you keep with you on all dives.

What is the difference between a primary and secondary dive light?

Expert divers know that it’s always wise to have a backup piece of equipment, just in case something goes wrong when underwater. For this reason, many divers care two dive lights when headed out for some night dives or cave diving.

A primary dive light is the one you use throughout your dive. It’s generally best to have a stronger light beam (higher lumen output) for your primary. You will also want this light to have a strong, long-lasting battery that is fully charged.

The secondary dive light is your backup. This is often smaller and lighter, so it can be put away in your BCD pocket. Generally, this light is only used if something goes wrong with your primary dive light.

What type of battery is the best for dive lights?

Some dive lights utilize traditional alkaline batteries. Many divers prefer this, as these can generally be found anywhere in the world. So, if you often dive in different locations around the world, this may be the best option.

Other dive lights come with lithium batteries. These types of batteries supply superior performance and are also more environmentally friendly. However, there are flying restrictions these days with lithium batteries, which can make travel more difficult.

Rechargeable batteries make a great money-saving option for those who dive regularly. The downfall of this option is the charge time needed. This can be a problem for consecutive dives as there won’t be enough time to charge during the typical surface interval.

What about the type of light bulb?

These days the vast majority of dive lights come with LEDs for the light source. Some still use the Xenon bulbs for the cheaper end models. But with the advent of LEDs that shoot out sunlight temperature beams, these are becoming less and less common.

You’ll need more than just light

A superb dive light will ensure you enjoy your dives more, but you will need some other items. So please check out our reviews of the best water socks, the best diving knives, our best wetsuit review, or even our review of the best underwater scooters currently available.

So, What are the Best Dive Lights?

You should now have a clear overview of the range and styles of dive lights currently available on the market. So, now all you have to do is simply make a purchase and head out to the big blue for some of the best dives of your life.

However, if you still haven’t managed to make up your mind, we would recommend the…

Light and Motion Sola Dive Light

This is a great dive light that you can trust won’t let you down. With its rechargeable battery giving two output settings of 1200 and 500 lumens, and its choice of wide flood beam or spotlight illumination, it will give you everything you want and more. However, quality costs and it’s reflected in the price.
