The Best Focus Lights for UW Photography in 2021

We consider a good focus light as essential to consistent success with underwater Photography. Here are our thoughts on the best of the bunch.

Fix Neo 1500 DXII SWR Premium: A favorite among photographers.

Why they are important

The reasons to use a focus light are many. It is always nice to have a light on a dive of course for dark overhangs and such, and an obvious essential on a night dive, but it is in assisting AF where these lights earn their value. It is hard to over emphasize what a difficult environment the underwater world is when it comes to using autofocus. In even the clearest Caribbean water, there are thousands of suspended particles in every foot of water the Camera has to look through that rob contrast and filter light. All this works against even the best autofocus as the the camera struggles to identify our subject. A light can help bring back some of that contrast and definition which in turn helps the autofocus lock on its subject properly.

So what makes for a good focus light?

This will vary a bit from one person to the next, but here are the "typical" considerations.

• Small size - no one wants to add much bulk to their rig.
• Light weight in water. Older style lights and some low-cost, less sophisticated lights are like a brick in the water
• Wide angle of coverage (60-110 degrees) - Focus lights should be close to zero fuss during a dive and that means it is set for wide coverage and shouldn't need to be re-aimed during the dive.
• A red light "stealth mode" is not essential, but a nice feature for shy subjects.
• enough power/runtime to last for your style diving (do you do 1 tank dive trips or 3 tankers?)

There are many other potential features, but these are the basics.

Can a focus light be used for video?

Sure - but if you want to take advantage of this, than it helps to have this a consideration from the start of your selection process. A 1000 lumen focus light is not likely to be very effective for video. We would probably suggest going to at least 3500 lumen if you intend to take video from more than about 10" away. But with more power, you also want to make sure you can adjust the power low enough for decent focus work (usually 500-800 lumens).

Our recommendations

Light & Motion 

This venerable light manufacturer has been in the game of lighting a long time and arguably introduced the first truly compact underwater LED rechargeable light for shooters years ago. The SOLA line was an immediate hit with divers.

Today the evolution of those lights are still popular and represent a lot of value for the money.

Sola Photo 1200

Pros:

• At $279 (current pricing), this is a lot of light for the money
• Extremely simple operation appeals to people that want minimal fuss.
• Has both white and red light (stealth mode).
• Still one of the smallest and lightest lights in this power range available.
• Adheres to FL-1 standards

Cons:

• The light only has 3 power settings, so limited tweaking.
• Sealed battery means no user changeable extra battery.
• Mounts purchased separately (adds $20)

Another brand that has been in the industry for a long time is Fix. Moving from halogen to LEDs years ago, Fix has always generated feature rich lighting of high quality. All Fix Neo lights are rated on the FL-1 Standard.

 Conclusions

There is clearly no one perfect light to suit everyone's needs. But these lights all shine (pun intended) in one or many areas. Equally important, these lights deliver what they claim and adhere to the international standards for measuring the quality and coverage of light without a noticeable loss in performance with battery charge decline. Are there other dive lights that could be used as a focus light? Sure. But they probably won't check all the boxes we are looking for and the price point some of these purpose designed lights are at, there is really no need to compromise.
