Illuminating the Best Scuba Diving Torches of 2019

Inexpensive and reliable LEDs have transformed dive lights in the past ten years. Mark ‘Crowley’ Russell rounds up the best, for everything from an occasional night dive to deep cave penetration

Nobody forgets their first night dive. Many divers of a certain age won’t forget their first underwater torch, either. It was big, garishly coloured, had a filament bulb that burned very brightly until just after you jumped, or perhaps went ‘pop’ when you turned it on, out at sea, in the dark, with no spare batteries.

Thankfully, time has moved on and today’s dive lights are brighter, smaller and much more reliable than their predecessors. Improvements in battery technology have been dramatic, but the game-changer was the advent of inexpensive, white-coloured LEDs.

WHAT IS AN LED?

A diode is an electrical component that allows electricity to flow through it in only one direction, and a ‘Light-Emitting Diode’ – LED – emits light while doing so, through a process known as electroluminescence. The colour of the light emitted can be varied depending on the material used in the LED’s construction.

Red LEDs are the easiest to produce and became commonplace in the 1970s in the displays of electronic pocket calculators. White LEDs first appeared in 1996, and while they were initially more difficult and expensive to manufacture, developments have since seen LED lighting come to dominate the market.

LEDs are brighter, use less energy, last longer, and are less prone to damage than filament or halogen bulbs. With advances in battery technology to match, most modern torches can last for several hours at their highest output before the batteries either need replacing or recharging.

TIPS FOR BUYING

There is a huge range of dive lights available on the market today, but as with other types of gear, you can narrow down your selection by the type of diving you are most likely to do. If you’re the sort of diver who makes one or two easy night dives a year in a tropical resort-based location with five other divers and a dive guide, then a small and compact, lower-priced torch is probably all you will need.

If you’re making night dives in a more remote or challenging environment, such as from a liveaboard, then you might want to invest in something of a higher specification. Spend more money if you have it, but it’s worth pointing out that turning up to a recreational night dive with a light that is too powerful sort of defeats the object of diving in the darkness – and won’t win you any beer-table buddies if you frighten all the critters away.

The larger canister lights are generally the preserve of cave or wreck divers, and techies will not need advice from this feature to make their buying decisions. However, those who might be seeking to join the dark side in the future might want to look at lights that are brighter, have a wider range of power modes, longer burn times, and can be used with a hands-free grip.

Thanks to the versatility of LED technology, there is an increasing number of lights that can be used both for peering at things in the darkness, or as video lights. If you think you might want a light to use for both options, make sure it has an adjustable beam angle. Remember that a torch is used for signalling underwater, which requires a tight, narrow ‘spot’ light to be effective. Wide-angle ‘flood’ lights don’t do this and shouldn’t be used as general-purpose torches.

RECHARGING

Some lights have removable, rechargeable batteries, some of which can also be used with single-use alkaline (such as AA, CR123 etc...) batteries. Other lights are sealed and can only be recharged using an appropriate cable (sometimes USB, sometimes not). For most people, it won’t matter either way, but if you might be diving in a location where power supplies are intermittent or unavailable, then being able to swap for a spare set of batteries might be a nice option

GETTING TECHNICAL

LUMENS A lumen is the SI measurement of the total amount of visible light emitted by a light source. Putting it briefly – the larger the number of lumens, the brighter the light.

SMD, COB AND CREE Surface Mounted Diode (SMD) and Chip On Board (COB) are methods of LED manufacture. COB is the most recent and most energy efficient, but SMDs are still widely used. Cree is the name of a leading manufacturer of LEDs.

BURN TIME ‘Burn time’ is a measurement of how long a light should operate continuously on a particular power setting from a full charge. This is realistically only a useful approximation. Different batteries last for different lengths of time, rechargeable batteries fade with repeated use, and the surrounding temperature can affect how quickly a battery discharges.

COLOUR TEMPERATURE The ‘colour temperature’ of a light is a measurement of how ‘hot’ the light appears to be (but not how hot it actually is). For example: an iron bar will glow red, then yellow, then white as it gets hotter, hence red is a ‘low temperature’ light, and white is a ‘high temperature’ light. Colour temperature is important for underwater photographers and videographers, as it helps to balance a camera’s sensors with the available light (white balancing). Colour temperature is measured in Kelvins on a scale ranging from an orangey-red 1,500K to a bluish-white 30,000K. Just to confuse the matter, low temperature orangey light is referred to as ‘warm’, and high temperature bluish-white light is called ‘cool’.

BEAM ANGLE Beam angle is a phrase commonly used to describe the width of the beam of light emitted by the torch. ‘Spot’ lights are narrow, between around 6° and 12° of width, and are best for general purpose diving – don’t forget that a dive light is also for signalling, which requires a tight, narrow beam to be effective. ‘Flood’ lights illuminate a much greater area – anything from around 45° to 120° – great for use with cameras, but poor for signalling underwater and shouldn’t be used as a primary light unless the beam angle can be tightened.

MODES Some lights are On/Off, others have variable power settings – 100%, 50%, 25% or variations thereof are common. Some lights have a strobe mode, which is a continually flashing signal designed to attract attention; others have an SOS mode, which repeatedly flashes the emergency signal at high power, should the need arise. Using lower power modes to extend battery life where possible is recommended, switching to high power only if it becomes necessary.
