Does the LUX 18 need a separate controller?

Yes. The five channels are driven by a compatible Lumishore multi-channel controller, which handles color mixing, white tuning and dimming. Without one, the fixture will not deliver its full range.

Can I use it in saltwater and rain?

Yes. It is IP68 rated and built with a powder-coated aluminum housing and frosted lens for harsh marine conditions. Mount it where the cable entry stays protected.

What beam pattern does it produce?

A 70°–90° oval beam. That spreads light widely across a deck or dock rather than throwing a narrow spot, so aim it to avoid glare into the cockpit.

How does it compare with single-color marine flood lights?

It is brighter and far more flexible, with tunable white and RGB channels in one fixture. Single-color floods are simpler and cheaper but cannot change color or white tone.

Is red light available for night use?

Yes. The red channel gives a low-glare option that helps preserve night vision. It is one of the five channels alongside warm white, cool white, green and blue.
