Keldan announces the LUNA 4X video Light

Published

on

Swiss-based compact light manufacturer Keldan have announced the LUNA 4X 6,000 Lumen video light. Upgrades from the product’s predecessor include an increased output of 50%, a 110° beam angle, and a colour rendering index of 82.

Here are the technical specifications for the LUNA 4X:

  • 6,000 Lumen Output.
  • 110 Degrees of Usable Beam Angle in Water (90 Deg using FWHM Standard).
  • 82 CRI.
  • 5000K Color Temp.
  • 200m Depth Rating.
  • 45 min Burn Time at 6,000 Lumen, 180 min Burn Time at 1,700 Lumen.
  • Extreme Efficiency from Custom Reflector and Dome Lens.
  • Magnetic Power Switch.
  • Intelligent Lithium Ion Battery with LED Status Indicator.

Beam angle in water when measured using the FWHM standard of 50% intensity is 90 degrees; however, that doesn’t accurately represent the beam pattern of this light. The usable beam angle is much wider thanks to a very even and gradual edge fall off. Battery packs can be easily changed in the field, supporting long shooting days, and an LED charge indicator provides battery info at a glance.

Thanks to its compact form factor, the light is perfectly matched in size with mirrorless interchangeable lens systems, DSLR cameras, and camcorders. The ultra wide lenses utilized by these systems demand a wide, smooth beam angle, and LUNA 4X delivers. LUNA 4X achieves remarkably accurate colour rendition thanks to its even spectral distribution.

The LUNA 4X is available now from Keldan dealers worldwide. For more information, visit the Keldan lights website: www.keldanlights.com.

Book Review: Shells of the World

Shells of the World: A Natural History by M.G. Harasewych

Shells of the world is a guide to the world of marine, shelled molluscs. And what a varied and interesting world it is. Some of my favourite things to find on a dive are detailed in this book, including disco clams (or Electric File Clams as they are correctly names), the cephalopods, giant clams and sea hares. There are also many on my wish list, top of which is the Nautilus.

Each chapter provides a detailed description of the species, along with beautiful images. You can dive deeper and discover where they live, both with global distribution and the habitat they prefer. Learn about their diet, reproduction and diversity.

Having dipped in and out of this lovely book over the past few weeks, it has inspired me to learn more about this group of animals that we see on most divers, wherever we are in the world. Some of the shells are incredibly intricate and beautiful. I have always agreed with never collecting, or touching, marine life. The description of a certain set of cone shells should be a warning to those that are happy to pick up marine life! One of the cone shells has a local name called the cigarette snail. Why? Because once the venom is in your system from this animal, you only have time to smoke one cigarette before the affects of the venom are fatal!

What the publisher says:

Mollusks are invertebrate animals with a remarkable natural history and a rich fossil record, and their shells are prized for their breathtaking variety and exquisite beauty. Shells of the World provides a wide-ranging look at the incredible diversity of marine mollusks. An informative introduction outlines the lineages covered, followed by a directory section, split into classes, that profiles a broad selection of different taxa to give a sense of their sheer numbers and variety.

  • Features hundreds of beautiful color photos, depicting both the live animals and their shells
  • Discusses mollusk evolution, anatomy, life cycles, behavior, and ecology
  • Describes unique characteristics, distribution, habitat, and size
  • Provides valuable insights into the conservation of the world’s marine mollusks
  • Ideal for malacologists and shell collectors everywhere

About the Author:

M. G. Harasewych is research zoologist emeritus and former curator in the Department of Invertebrate Zoology at the Smithsonian Institution’s National Museum of Natural History. A fellow of the American Association for the Advancement of Science, he is the author (with Fabio Moretzsohn) of The Book of Shells: A Life-Size Guide to Identifying and Classifying Six Hundred Seashells.
