How to Choose a Dive Video Light: A Deep Dive Into the VL16 Series
There's no shortage of dive lights, scuba lights, and underwater video lights on the market — the spec sheets all look similar, but prices can vary wildly. Most people shopping for their first underwater video light end up guessing: more lumens is better, right? Does CRI actually matter? Do I need two lights or is one enough?
This post walks through those questions one at a time, then lands on our two best-selling entry-level lights — the VL16 A and VL16 B — so you can figure out if either one is right for you.
Start With What You're Shooting On
Before you even start browsing lights, take stock of what camera you're actually using. Different gear needs very different things from a light.
Smartphones (in a waterproof housing) — small sensors and limited light-gathering mean phones lose color and detail fast just a few meters down. Without a strong, color-accurate external light, footage tends to look flat and murky almost immediately.
Action cameras (GoPro, Insta360, etc.) — wide-angle lenses with relatively small sensors, so footage washes out or turns green fast. You need a gopro dive light with enough power and an even beam to bring the detail and color back.
Compact cameras / mirrorless bodies — better auto white balance and dynamic range than phones or action cams, but natural light still fades fast past a few meters, so you still need a diving video light to keep colors accurate.
Professional video / photo rigs — need higher brightness, more accurate color, and even beam coverage, which usually means running two or more lights together since a single light rarely meets professional output standards.
Once you know your gear, it's much easier to tell whether an entry-level dive video light is enough, or whether you should be looking at something more advanced.
What Do You Actually Shoot?
Different subjects call for different things from a diving light video — brightness, color temperature, beam angle all shift depending on what you're shooting:
Wide Angle — reef scenes, wrecks, big open compositions. You need a wide beam angle with even, soft light, or the frame ends up bright in the middle and dark at the edges.
Macro — nudibranchs, shrimp, small critters. The beam needs to be tighter and more controllable, or everything around the subject goes pitch black.
Underwater Video Vlogging — everyday dive footage where you want something light, bright, and flattering on camera.
Marine Life — documenting reefs and marine ecosystems, where you want gentle light that doesn't spook animals while still keeping colors accurate.
Night Diving — footage depends entirely on artificial light, so brightness and battery life become non-negotiable.
Commercial / Professional Production — needs top-tier image quality, precise color management, and multi-light setups that entry-level lights usually can't deliver.
The VL16 series is really built around four of these: Wide Angle, Underwater Video Vlogging, Marine Life, and Night Diving. If your shooting falls into any of these, VL16 is a solid, budget-friendly place to start. If you're aiming at commercial cinema work, jump ahead to the positioning section below.
How Much Brightness Do You Actually Need?
Brightness is the spec everyone fixates on — and misunderstands the most. The underwater videographers we work with tend to use a rough rule of thumb like this:
Each VL16 A tops out at 8,000 lumens, and each VL16 B at 8,900 lumens — enough to cover everything from casual vlogging to light professional work as a single light. Pair two together and you're getting close to a professional-level setup.
Why These Two Lights Sell So Well
Both lights also come with IPX8 waterproofing, an 80-meter depth rating, an aircraft-grade aluminum body with multi-layer corrosion resistance, and a dual-button lock to prevent accidental activation — solid build quality for an entry-level pro underwater video light.
What's the Difference Between VL16 A and VL16 B?
On paper the two are nearly identical — 120° flood beam, 30-meter beam distance, CRI 94, IPX8 waterproofing, 80-meter depth rating, and the same three-cell 21700 battery system. What actually sets them apart is the LED layout, and the light quality that comes with it:
VL16 A runs on a single high-power COB LED. A COB emits from one unified surface, so the light comes out smoother and more even, without the layered shadows or overlapping hotspots you sometimes get from multi-point arrays. On camera, that reads as softer, more natural light — a good match for close-ups of coral and soft-bodied marine life, where smooth tonal transitions matter more than raw punch.
VL16 B uses eight main LEDs plus four red and four blue auxiliary LEDs (8+4+4), pushing max output to 8,900 lumens. Stacking more light points gives you more raw brightness and wider coverage, but the footage tends to read a bit cooler and harder-edged, with more punch — useful for cutting through murky or low-visibility water.
In short: the specs are nearly the same — what actually separates them is the feel of the light. VL16 A leans soft and natural, ideal if you want a gentler, more organic look. VL16 B leans cooler and sharper, better suited to low-visibility conditions or footage where you want maximum clarity and punch. Think of it this way: VL16 A behaves like a softbox, VL16 B behaves like a spotlight — one flatters the mood of the shot, the other flatters the sharpness. Both also switch to red and blue auxiliary light, letting you observe marine life or shoot fluorescing coral at night without startling animals with a full white beam.
Where Does the VL16 Series Fit?
VL16 is an entry-level series — meant to give people just starting out in underwater videography a real bump in image quality without spending a lot.
Who VL16 probably isn't for
1-Commercial production teams that need very high, stable output across complex multi-light setups.
2-Cinema-grade underwater film work, which usually calls for 15,000+ lumens, tighter color temperature control, and a more elaborate rigging setup.
Who VL16 is a good fit for
1-Beginners who want one light to noticeably improve their footage.
2-Creators shooting underwater vlogs on a GoPro or Insta360.
3-Divers who enjoy shooting coral reefs and marine life.
4-Night divers who need a reliable light — arguably a must-have for night diving.
5-Wide-angle shooters going after big reef or wreck scenes.
6-Anyone who wants a well-rounded diving video light that balances brightness, color, and price.

Whether you just picked up a phone housing or a GoPro and want cleaner underwater footage, or you're already shooting coral and marine life and looking for a dependable scuba flashlight that doubles as a real video light, both the VL16 A and VL16 B deliver near-professional lighting without the professional price tag. Go soft and natural with the A, or bright and sharp with the B — either way works, it just depends on your style.
