What our customers are saying about Kraken KS40 Flash dive light

Kraken KS40 Flash dive light

Good flash for macro.

2025/07/25

Felipe

A very good flash, ideal for macro photography due to its small size and good power. It has details I miss in other flashes, such as the red focus light and the excellent layout of the controls. I would buy it again.

Ideal buyer profiles

General buyers seeking a dedicated underwater flash

This buyer is looking for a specialized lighting solution for underwater photography and videography. They require a reliable, powerful, and easy-to-use flash that can enhance the quality of their underwater images by providing consistent and adjustable illumination.

The Kraken Ks40 meets these needs with its 40W power, multiple power levels, and a 500-lumen focus light for superior underwater vision. The manual mode and included mounts like the ball mount and YS adapter ensure it can be easily integrated into an existing underwater camera setup.

Competitive features

When choosing essential diving equipment, it's important to understand how different items serve specific needs. We're comparing the Kraken Ks40 Flash Dive Light to a selection of other specialized gear, including a dive computer and various spearfishing fins. This analysis highlights the unique function of each product to help you select the right tool for your underwater activities.

Where it excels

The Kraken Ks40 is a dedicated underwater photography flash, providing powerful and adjustable lighting to enhance image quality in dark environments. It features a 500-lumen focus light and a red light mode, offering versatility for different shooting conditions and marine life. Constructed from aluminum and including both a ball mount and YS adapter, it is built for durability and compatibility with various camera setups.

Consider alternatives if...

If your primary need is monitoring dive metrics like depth, time, and air supply, a dedicated dive computer such as the Mares Smart Air would be the appropriate choice. For activities focused on propulsion and efficiency, such as spearfishing or freediving, specialized fins like the Go N Sea or Epsealon models are necessary. This product is not a primary dive light for general navigation; it is a flash designed specifically for underwater photography.

Verdict

The Kraken Ks40 Flash Dive Light is a specialized tool for underwater photographers, not a direct competitor to dive computers or fins. It excels in providing powerful, versatile, and long-lasting illumination for capturing high-quality underwater images. While alternatives like dive computers and fins are essential for other aspects of diving, the Ks40 is a purpose-built solution for those looking to significantly improve their underwater photography.
