FAQ-IconFrequently Asked Questions

Power & Electrical Systems

Q - Do I need a DC transformer as the power of the original Halogen lights I am replacing is 110v 60hz?

A -    Yes, you will need a power source of 12 to 24 VDC

Q - How do I know the correct wire diameter, switch and fuse to use?
A - Electrical components should always be installed by a knowledgeable and qualified individual. Wire gauge and fusing requirements are based on circuit load and configuration and therefore will vary by installation. In all instances the wire gauge should be large enough to accommodate the total circuit load, and fusing should prevent overcurrent events on the circuit. Lumitec lights do not require additional components such as dimmers and proprietary switches. Complete installation instructions for each product are included in each package.
Q - Some of your lights are rated for 12VDC, but my boat only has 24VDC where I want to install the lights. Is there any way to use your 12VDC on a vessel’s 24VDC power system?
A - Yes, by running 2 of our 12VDC lights in SERIES the lights can be operated on a 24VDC system.

Light Color, Control & Dimming Function (TTP)

Q - How do I change the output color on multi-color lights?
A - Multi-color or multi-output lights may Lumitec's TTP technology.  To change the output color or output mode of a light, briefly toggle the light OFF then immediately back ON.  The light will cycle to the alternate or next output color.
Q - How do I know that the color of my lights will match?

A - Lumitec carefully selects LED's with tightly controlled color outputs to ensure color consistency from product to product, and even from product family to product family. The human eye can detect about 10 million different colors. This means that even minor variations in output hue across a group of lights can be detected, and may be unappealing in some situations. Lumitec carefully selects "Bins" of LED's (batches of LED's that have been grouped together by the manufacturer because they have extremely similar output) so that output hue is consistent from light to light and product family to product family. In many instances Lumitec's LED suppliers such as Cree and Phillips Lumileds will design and maintain Bins exclusively to Lumitec's exacting specifications.

In 2012 Lumitec introduced "ColorMatch": a way to ensure that all of the lights for a given application have the same output hue. The ColorMatch system ensures that output hues (e.g. warm white, neutral white, blue, red, etc.) are consistent between individual lights within a family, and between different product families.

Q - What is color temperature, or Corrected Color Temperature?
A - The output hue of white LED lights is often described in terms of "Color Temperature" or "Corrected Color Temperature", expressed in units of Kelvin. In short, CCT approximates the surface temperature of an "ideal" heated light-emitting body- for example the tungsten filament of an incandescent light bulb. Typical color temperatures for white LED's range from about 10,000 K, which is distinctly blue, to a natural daylight white at 5000 K, down to the yellower color of a traditional incandescent light at about 2700.
Q- What is "TTP"?
A - TTP is Timed Toggle Protocol.  It is a technology developed and refined by Lumitec which enables sophisticated features like dimming and/or color change with no external control boxes or specialized switches.  The light is installed like any 12 or 24VDC light: using a positive and negative power wire controlled by any standard ON/OFF switch. 
Q - How do I Dim TTP-Equipped Lumitec lights?

Lumitec Lights with dimming functionality ramp up in intensity over a period of about 4 seconds when initially turned on.  A brief "Off/On" toggle of the switch during the ramp phase will interrupt the ramp and hold the light at that intensity

Q - How do I change colors or change output modes of TTP-Equipped Lumitec lights?
A - Multi-color or multi-output lights may Lumitec's TTP technology.  To change the output color or output mode of a light, briefly toggle the light OFF then immediately back ON.  The light will cycle to the alternate or next output color.

Underwater Lights

Q - What is the recommended spacing and/or depth for underwater lights?
A - Many factors will govern the placement or your underwater lights, including the location of a flat mounting surface, the ability to safely run power to the location, and the location of engines, struts, trim tabs, etc. which may obstruct the light output.  Although Lumitec underwater lights can be run above water, they perform best when completely submerged 8" to 16" below the water.  For inboard boats: generally speaking 1 light for every 2.5 to 5 feet of beam provides good results.  For outboard and stern dive vessels, good results are generally acheived by installing lights outboard of engines, and between engines.  For example, a twin engine vessel would use 3 lights, a triple engine vessel would use 4 lights, etc.
Q - What are the modes of operation for the SeaBlazeX products?

A -    Dual Colored Lights:

  • Mode 1: Cross-Fade - randomly cycles between blue and white
  • Mode 2: 6 white emitters illuminated at full power
  • Mode 3: 6 blue emitters illuminated  at full power
  • Mode 4: All 12 emitters illuminated at full power
  • Mode 5: Strobe - random strobe pattern using blue and white separately

Single Colored Lights: 

  • Mode 1: All 12 emitters illuminated at full power
  • Mode 2: Cross-Fade - dims and intensifies the light level intermittently
  • Mode 3: Strobe - random strobe pattern
Q - What are the modes of operation for the SeaBlaze 3 products?

A -    Dual Colored Lights:

  • Mode 1:        4 white emitters illuminated at full power
  • Mode 2:        4 blue emitters illuminated at full power
  • Mode 3:        All 8 emitters illuminated at full power
Q - Can I run the SeaBlaze underwater lights out of water?

A - Yes. All of our SeaBlaze lights incorporate a thermal foldback protection mechanism which will ensure the sophisticated internal circuitry does not overheat. Note however that the lights are designed for underwater operation. In some instances the thermal foldback circuitry may reduce the power (heat) of the device, therby reducing the light output. The light will return to full intensity once it is again operated underwater

Q - Do I need to bond the SeaBlaze lights?
A - Lumitec does not recommend bonding of the SeaBlaze underwater lights.
Q - What sealant is recommended for the underwater lights?

A - A high quality sealant designed for below waterline applications is recommended.  3M 4200 is one such sealant.

Q - What type of paint do I use if I am going to paint my underwater lights? What is the process I should follow if I am going to paint?

A -    While painting your underwater lights is not necessary, there are a few guidelines to follow if you choose to do so:

  • Ensure that your existing bottom paint is compatible with the light's housing (aluminum for SeaBlaze2, SeaBlaze3, SeaBlaze Mini and bronze for SeaBlazeX);
  • If the existing paint is NOT compatible, take measures to isolate the bottom paint from the light to prevent electrolysis and corrosion.  Non-compatible paints should not be applied within 1" of the light housing.
  • Do NOT sand the housing prior to applying paint. Sanding will strip the protective finish from the surface and increase the likelihood of corrosion.
Q - Where can I see the difference between the underwater lights?
A - Please visit for technical data and side-by-side comparison photos of the SeaBlaze family of lights.

Installation & Maintenance

Q - Do the Lumitec lights come with everything you need to install?
A - Mounting hardware is included with all Lumitec lights.  Electrical connections are unique to each installation and as such butt connectors, bus bars, fuses, switches are not included.
Q - Is there a way to open up my lights to do repairs or change components?
A - No, your Lumitec lights are sealed at the factory. 
Q - What do I use to clean my lights?
A - Solvents, harsh chemicals, or abrasive/scouring pads should not be used for cleaning.  Mild soap and water is generally sufficient to remove grime and salt spray. Underwater lights may be cleaned with a nylon brush and flexible straightedge to remove growth on the lens surface and housing as necessary.
