Understanding the Basics of Underwater Lighting

May 1st, 2013 | Technical ResourcesUnderwater Imaging

In subsea photographic and video imaging applications, one of the challenges that system designers, integrators, and operators face is bringing along all of the light they will need for tasks below depths of about 150 to 250 m. At these depths, an understanding of how light propagates through water helps designers and users balance mission requirements against the real-world constraints of underwater lighting while helping them make informed lighting choices.

LEDs are Now the Choice for Underwater Lights

LEDs are Now the Choice for Underwater Lights

May 1st, 2011 | Press ReleasesUnderwater Imaging

Properly designed underwater LED lights can be “plug & play” replacements for halogen lights. They can operate using the same wide choice of connectors, the same input power (120VAC or low voltage DC), and the same dimming controls (variable voltage or phase control dimming) as the halogen lights that they replace. This makes it easy for underwater operators to significantly upgrade the lighting that they use without encountering complex or costly changes in the process.

Advanced Underwater LED Power Supply and Light Control

May 20th, 2010 | Press ReleasesTechnical ResourcesUnderwater Imaging

While great attention is given to LED solid state devices during their rapid evolution, they are just one component in a larger electronic circuit. LEDs are tiny, fragile devices that will be easily damaged if allowed to overheat or if exposed to excessive voltage or currents. These devices need an external electronic circuit, commonly called a driver, to safely control the power applied to them. This article will look at the driver circuitry behind the light emitters.
