General Knowledge

IP stands for Ingress Protection, and is followed by a two digit number, such as 65. The first number stands for the light’s protection level against dust and particulate. This first number in the IP rating is on a scale of 1-6 with a 6 being the highest rating. The 6 in all Highliner IP ratings state that the fixture is protected from any dust and particulate. The second number stands for the light’s ability to deter water ingress, the most important factor to keep in mind for marine applications. Here is a table with information about water ingress. That second number in the IP rating should be a 5 or higher. A 5 states the fixture is protected from water sprays from all directions, the 6 stands for protection against low pressure water jets and waves, 7 stands for protection against string water jets and waves, 8 stands for protection against temporary immersion up to 3 meters, and the last is 9 which is the rating for a fixture that is protected against pressure washing and prolonged immersion under pressure.

Upgrading your existing lighting to LED has four major impacts on your business Increased Productivity – It is easier and more efficient to work in the right amount of light, and the right color or light. Working in an environment with 5000K daylight white is easier because our eyes are more used to working in that type of condition versus the orange light from high pressure sodium lights. Decreased Maintenance – Everyone knows that LEDs last over 50,000 hours, but in the marine industry those LEDs only last 50,000 hours if the fixture can withstand the harsh environmental conditions they are in. Highliner fixtures have the best possible coating, components, and overall design to protect them from corrosion, water ingress, and overall fixture failure. When your lights last that long you don’t need to worry about maintenance. Improved Safety – With your crew working under a higher volume of light, and a more natural color of light it is easier to avoid hazards. Working in brighter conditions also helps lower operator fatigue, like the effect of attempting to read in a dimly lit room. Also, now that your lights are no longer burning out you don’t have to send the greenhorn up the mast to change bulbs. Economic – With LEDs lowering required power by 70%-90% that creates a lower amp draw on the generator. With that lower draw on the generator you are now consuming less fuel, and therefore saving money while getting better performance out of your lighting. LED lights require dramatically less power than traditional bulb-based lights, reducing the load on your vessel’s generator. Lower generator load means lower fuel consumption and a savings in actual operating costs --- depending on how many hours per day you use your new LED lights, the fuel savings alone can cover the cost of the new lights within their warranty period.

Color temperature is a measure of a light’s appearance – think of your incandescent lights at home compared to the bright white lights that you see in a sports stadium. Highliner lights are offered in a “daylight white” color of 5000 Kelvin (K), which is the natural color of daylight – the best we’ve found for most lighting applications. For fog-cutting look forward applications, we offer lights with an amber color measuring 2700K – the amber LEDs have a longer wavelength that is more effective at penetrating fog – without the bounce back that is typical of white lights.

Lumens are the measurement of output of a light source – regardless of the light’s installation. Think about a 100W light bulb mounted 3’ above your desk or25’ above your desk. Both have the same lumen rating, but clearly the higher mounting height will result in less light on your desk. Lumen rating can be a useful figure when comparing output for a given amount of power consumed. One thing to keep in mind is that lots of lighting manufacturers publish the lumen output based off the capability of how much light the LED can produce, not the actual amount of light the fixture is delivering. Manufacturers that give an accurate account for how many lumens the fixture delivers typically specify with “delivered lumens,” “actual lumens,” or “landed lumens.” The factors that take away from the potential lumen output are things like the power supply, how efficiently the LED is being run, the optic or reflector, and the lens. So, lumens are a good measure of a lights output but they can be misleading. A more useful way to measure light is to examine the amount of light on your target working area – which is a measurement in lux or foot candles.

Foot Candles and Lux are measurements of the amount of light in a given area. 1 foot candle (fc) is equal to 10.1 lux. These are the measurements taken by a light meter. These are also the measurements we use to determine what lights are recommended in the Lighting Recommendation Tool.

It depends on the application. For deck lighting you should have at least 200-250 lux (20-25 fc). Inside the engine room you should have over 300 lux (30 fc). To help put things in perspective an office or classroom setting has about 400 lux. We recommend 250+ lux on the deck in order to work in a safe environment, avoid operator fatigue, and to work more accurately and efficiently.

Highliner Policy

The Highliner warranty covers defects in manufacturing.

Products may be returned to Highliner Lighting with the written consent of a duly authorized officer of Highliner Lighting in advance of the return being made. Approved products for return will be given a Returned Material Authorization (RMA) number which needs to be clearly marked on the outside of the packaging of the returned products. Returned products without an RMA number will not be accepted. Products may not be returned unless they are in marketable condition, and delivered to Highliner Lighting without damage. Products may be shipped back to Highliner Lighting, with an RMA number within thirty (30) days of invoice without penalty. Products shipped back to Highliner Lighting within ninety (90) days are subject to a twenty percent (20%) restocking fee at the discretion of Highliner Lighting.

If the light is in stock than orders will ship out typically the next day, and within two business days at the latest.

You may cancel your order prior to it shipping out at any time. You may also return the product, with RMA number, within 30 days without penalty. Approved orders returned within 30 days will be subject to a full refund on the credit card used during the initial purchase.

We use UPS or USPS shipping for all our orders. Please call us for express shipping.


While we recommend that you have your Highliner lights installed by a professional electrician, the connecting wires are marked to indicate Line, Neutral, and Ground connections.

Each Highliner light is labeled with the appropriate power connection, with DC or AC voltage ranges identified. DC voltage models are available – please see the Details section of each light’s product page when selecting which lights to purchase.

The wire must be rated to carry the current load (amperage) of the light at the appropriate voltage of the power supply. DC voltage installations must consider the length of the wire. Below is a table with typical light wattages, vessel voltages, and acceptable wire sizes based on the light’s current or amperage draw. To calculate your amperage draw, use this formula: Amperage = Power (Watts)/ Voltage. For example, the current draw for a 500W halogen light in use on a vessel with a 220V lighting circuit is 500W/220V, or 2.27A (amps).

Highliner LED T8 tubes are different than most other LED T8 tubes. Most other tubes receive power from only one end, where one pin is line and the other is neutral. This can become an issue because ships are constantly vibrating, and that creates wear and tear on the tombstones holding the T8 tubes, especially if they are old fixtures. If one of the pins on the tombstone fails, then the entire tube loses power. And, depending on how the fixture is wired, the other tube could lose power as well. For this very reason, the Highliner LED T8 tubes have power on both ends. Both pins on one side are neutral, and both pins on the other side are line, it does not matter which side you wire up as line or neutral, the tube will work either way. If one pin on a tombstone fails the other pin will still be powered and the tube will continue to work.

The ballasts need to be removed, or bypassed. LED lights do not use these ballasts. If you do not bypass the ballast it will fry the power supply in the light, and possibly the LEDs themselves.

The Right Light

Most general lighting applications will find that a 60 degree beam angle is a good fit. If the mounting height is higher than 30’, a narrower beam angle of 40 or 45 degrees will result in better light coverage on the target area. In applications where more light is needed side-to-side than distance, an asymmetric beam angle of 60 degrees x 135 degrees can provide a better solution.

Highliner LED lights will provide the same light output of bulb-based lights at much lower power consumption – reducing generator fuel consumption. Here is a table with guidelines for how to decide the right wattage of your replacement Highliner LED light. One caveat – if you’re not satisfied with the amount of light from your current installation, consider moving up one level for your new light (e.g. instead of choosing a 50W LED to replace your aging 500W halogen, step up to a 100W LED).

Highliner lights are either ETL or UL certified – both certifications indicate that Highliner lights have passed stringent requirements for electrical safety
