FAQ
What is the difference between using a switch and using a Shadow-NET product with this light?
When wired to a standard on/off or color-selector switch, the SCM-10-EXT-CC gives you access to 12 preset standard colors. When paired with a Shadow-NET enabled controller or app, you unlock unlimited color mixing, dynamic lighting effects, and synchronized control across multiple lights - giving you full creative control over your boat's underwater lighting.
Is this light safe to use on boats that are trailered or stored on a lift?
Yes. The SCM-10-EXT-CC features thermal throttling technology that allows safe operation even when the unit is temporarily out of the water. This makes it ideal for trailered boats and lift-stored vessels where the light may be energized while exposed to air.
Can this light be used in saltwater?
Absolutely. The housing is constructed from passivated 316 stainless steel - one of the most corrosion-resistant alloys available for marine use. Combined with the clear-gel-filled, fully sealed design and IP68 waterproof rating, this light is built to perform reliably in both fresh and saltwater environments.
How many lights would I need to fully illuminate my boat's hull?
This depends on the size and shape of your hull. The SCM-10-EXT-CC covers a 120-degree beam angle and produces up to 3,750 lumens, making it highly effective as a single light for smaller vessels. Larger boats typically benefit from two or more units spaced evenly along the hull. If you plan to run multiple lights, Shadow-NET compatible controllers can synchronize all units into a unified lighting display.
What voltage systems is this light compatible with?
The SCM-10-EXT-CC accepts an input voltage range of 10-30 volts, making it compatible with both standard 12V and 24V marine electrical systems. No additional voltage converter is required for most boats.
