Choosing the correct dive light is crucial whether your exploration is of dark caverns or appreciation of nighttime marine life. Choosing your main dive light and backup calls for some simple guidelines to bear in mind. A scuba diver's light can assist restore colours lost at deep, enhance the quality of underwater footage, and highlight tiny life in crevices. One can also use it to signal an emergency either above or below sea level.
Like xenon, HID lamps run on an arc tube filled with a combination of gases including a noble gas. The metal additions in the lamp define the colour created by the arc tube. Kelvin scale colour temperatures arise from different metals producing light at different wavelengths.
First meeting Josha and Robbie at Lookout Landing, the two will offer to scan a map of The Depths for you. Useful for lighting the gloom-lined caverns of The Depth, Josha will also hand Link over 10 Brightbloom seeds and 5 arrows.
Look for big root clusters glowing a dull orange hue while exploring The Depths; these are known as Lightroots and serve like Shrines or Skyview Towers. Interacting with a Lightroot maps the surrounding region and generates a fast transit location, therefore facilitating the exploration of sites of interest.
One of the most often used kind of light bulbs are incandescent ones. They generate thermal radiation in the form of visible and infrared light by use of a heated filament driven by electric current travelling over it. Either a vacuum or an inert gas makes up the surrounding glass envelope to hold heat from the filament and stop it from vaporising. Working well with both AC and DC power, they are cheap to build and flexible in a range of voltages, light output, and current. They also have a high CRI rating, which indicates their very good rendering of colours.

Wider beam angles of a diving light will help to highlight more of the surrounding environment. This will facilitate your more rapid identification of marine animals and threats. When there is little ambient lighting or on challenging dives when clear communication is crucial, this kind of light can be quite helpful.
A light that can generate a steady wide-angle beam is crucial for anyone wishing to record underwater images and films. This will prevent hot spots—which can overexpose your subject.
A decent photo/video light features a small beam lens for peering in holes and ledges, a diffuser for the wide-angle beam that fits GoPro cameras, and red or UV light to maintain night vision. Its high battery life and comfortable grip also count.
Your main dive light should ideally be strong enough to highlight the whole underwater scene. For flexibility, it should also provide a tiny 10-degree spot beam and a broad flood beam. Many lights additionally feature SOS mode and a built-in intermittent emergency strobes.
If you frequent diver, think using a rechargeable model. Although they start more expensive, over time they will save you money. Furthermore aeroplane safe and will give you more instantaneous power than alkaline batteries.
Burn tests help you to routinely ensure that your dive light is in good operating order. This will enable you to schedule battery replacements such that the performance of your light is maximised. At last, keep in mind to avoid shining the beam straight into the eyes of other divers, therefore practicing correct dive light etiquette.
