LED Spearfishing Lights

Spearfishing is an activity that requires presence of mind and fast reaction to changing environmental factors. These high-risk elements require powerful LED lamps for illuminative support. LED spearfishing lights can come in the form of a compact LED flashlight, an LED helmet lamp or an LED diving light.

Mounted LED Spotlights

Hands-free lighting is recommended for divers and spearfishing-related activities. Individuals can opt to install a micro LED flashlight with a bracket on their spear gun. This configuration is similar to the use of an LED light mounted on a blasting gun in industrial sites. By securing the LED lamp on the spear gun, accuracy of light beam placement is greatly improved, as the beam follows the general movement and aim of the gun. For spear guns, the LED light is usually mounted below or at the side of the holder.

Divers could also mount LED spotlights on helmets or other types of head gears. This setup is useful for seeking out underwater locations for spearfishing. Alternatively, it would be possible to mount an LED light on one’s wrist, using a flexible strap or holder. With the luminary readily accessible at all times, divers can react to unforeseen dangers quickly.

Underwater LED Floodlights

At the start of an underwater spearfishing session, divers must first find an ideal fishing spot. This is typically carried out using LED floodlights. The wide beam pattern enables comprehensive coverage of underwater environments. A submersible LED light bar is a great example of such equipment.

To make operation seamless, LED lamps for fishing should come with features that enable direct activation. For instance, a twist-to-activate feature is perfect for divers because it caters to gloved hands. Large, visible pushbuttons may also be suitable for such activities. In addition to waterproof protection, individuals could benefit from shockproof features due to the rugged nature of spearfishing sites.

Types of LED Mounting Solutions in Offshore Oil Rigs

Offshore oil rigs lack conventional and sturdy mounting options, due to the remote setting and type of tasks carried out in the hazardous location. For lights, many oil rig operators look to portable and seamless LED mounting solutions for proper illumination.

These days, there are several types of portable mounts available for offshore oil rigs, which can be setup without tools or extra hardware.

Ladder and Magnetic Mounts

On remote oil rigs, portable mounts consist of components that can easily be setup and removed at various sections of the work site. An ideal solution makes use of existing structures in the surrounding area. With this in mind, a scaffold or ladder mounting component for LED lamps is recommended for such facilities. This type of mount can be utilized at almost all parts of the rig, from confined spaces (inside tanks) to makeshift walkways and entry or exit points.

Magnetic mounting options also perform well in remote offshore sites. Without any additional tools, operators can easily secure battery-powered LEDs, strobe lamps and other types of compact LED lamps on compatible surfaces. As there are numerous tasks around oil rigs that require gloves, magnetic mounts ensure workers keep their hands protected at all times by forgoing the need for tools during setup.

LED Drop Lights and Hook Mounts

Like ladder mounts, LED lights with hooks are reliable forms of illumination on oil rigs. LED drop lights traditionally incorporate hooks at the light head, which facilitates mounting at various places in the facility. Furthermore, the units are less bulky than ladder or scaffold mounts. This feature is ideal for lighting up tight spaces around the site, as well as for illumination during inspections.

Lastly, hook mounts may be applied to chain or suspension-mounting requirements around the remote site. This type of mount provides temporary, overhead lighting in areas without flat surfaces.

Illuminating Confined Spaces in Shipyards with LED Lights

Confined spaces exist in a myriad of dangerous industries. Shipyards, mining sites, construction and tank storage facilities are examples of operations wherein confined spaces are abundant. OSHA and other safety regulators have set forth several regulations to promote safety in and around confined spaces. This article outlines how LED lights can boost illumination in confined spaces and explosive environments.

Example of Dangers in Confined Spaces  

In IMCA Safety Flash 32/17, the notice highlighted an incident involving painters and a large tank. One of the workers became trapped inside the tank, when the other painter closed the manhole cover, assuming no one was inside. This led to the worker being stuck in the confined space. After 15 minutes, another individual passed by and heard noise coming from the tank and set the painter free.

Although a buddy system was implemented, it was not enough to prevent the issue. Furthermore, investigation into the matter revealed the individuals did not hold a valid work permit for the task. As a result, control measures were compromised.

LED Lights for Confined Spaces and Shipyards

LED lights can help increase safety in confined spaces. Taking the scenario above, using an explosion proof manhole LED light may have indicated that work was being conducted in the space, preventing the individual from closing the entry/exit point.

Portable LED light towers that cast intense light over the site can also be setup, to improve productivity inside the tank. Any worker passing by will be able to see traces of the light from the LED light tower, indicating activity inside the confined space.

Additionally, explosion proof cameras could be setup inside the tank to monitor the presence of workers in real-time. Explosion proof, wireless gas monitoring devices may also be deployed to check for the accumulation of combustible materials in the area.

How to Attract Fish with Green LED Fishing Lights

Fishing at night is an exciting and rewarding experience, with the right equipment. Unlike fishing during the day, anglers use special equipment to locate and attract sea creatures. Light during nighttime fishing serves two very important purposes. Boat lights provide general illumination around the vessel, ensuring proper use of equipment and guided visibility on the boat. Green LED fishing lights are used to attract and entice fish in the water.

Green LEDs and Fishing

Green light is used to stimulate zooplankton in the water, as the creatures are naturally drawn to the light due to reproduction. Other light colors, such as white, also have similar effects. However, green is capable of penetrating the water better, ensuring maximum reach of the light beam. Blue light is applicable to fishing in saltwater, as the light color is ineffective in attracting zooplankton lurking around in fresh water locations.

Anglers deploy green lights using floating pods that rest on top of the water. The light beam is pointed downwards and individuals simply keep track of the unit with a string tied to the boat or a pole.

For areas prone to insect gatherings, floating lights are not recommended. Instead, submersible boat led lights should be used. This also improves the reach of the light beam in murky lakes and bodies of water. Submersible green LED fishing lights should only be submerged roughly three to five feet in the water.

Tracking Lines and Fishing Equipment

To improve fishing techniques and catches, anglers may utilize black lights. With several rods casted, it may be difficult to monitor every single line. Black lights may help detect slight movements and bites from the boat, without distracting fish and the water.

Equipment with fluorescent tips, such as fishing rods and lines, or other reactive color signatures glow when exposed to black light. Because of this, slight movements are extremely visible.

LED Buoys and Safe Navigation

In active bodies of water around the world, navigational markers are prevalent. Such components include beacons, day boards and buoys. Lighted buoys have been around for some time and serve as important safety mechanisms for boaters and commercial vessels. Read on to understand how LED buoys work and their applications in the marine sector.

Flashing Green or Flashing Red

The most common types of lighted buoys are equipped with either a flashing green light or a flashing red light (can be both). The flashing pattern varies, depending on the unit’s application. In most cases, two buoys close to each other must have opposite flashing patterns for seamless identification.

Furthermore, there are several standard flashing patterns implemented by the US Coast Guard. Such strobing configurations include the following: Quick Flashing, Isophase, Group Flashing and Composite Group Flashing.

For example, illuminative navigational aids found when entering a channel flashes a green/red light (2+1) with 6-second intervals. The lighting configuration is reversed when exiting a channel. Lighted buoys may also be used to mark dangers in the water, signaling to boaters to exercise caution during an approach.

Solar LED Buoy Trends

Maintaining lighted buoys is a meticulous process, as large bodies of water may have numerous units floating around throughout the day or night. In order to reduce such tasks and improve reliability, LEDs are being used for signaling and illumination.

In locations wherein sun exposure is frequent, marine-based operators may also utilize solar LED strobes or lamps on the buoys. The entire system can run for roughly two years before replacement. It is important to consider that the batteries used to power the lights are usually the first to fail, as LEDs have an expected lifespan of 50,000+ hours.

To prevent damage, a watertight enclosure should be used, as well as UV inhibitors for protection from persistent sunlight exposure.

Inspecting Boats Using Infrared LED Lights

Inspections on boats and hulls must be conducted on a regular basis in order to boost reliability. To uncover inconsistencies on the surface of vessels, inspectors leverage a myriad of different types of equipment. Moisture meters are commonly used to detect the build-up of water between materials, while sounding hammers are frequently applied in determining various levels of durability. When it comes to lamps, infrared LED lights can be deployed to locate damage during boat inspections.

Thermal Imaging and Boat Inspections

Most LED infrared boat lights used for inspections are built directly into the camera. However, it is also possible to use a standalone LED infrared spotlight to illuminate targets on and around the vessel. The beams are non-visible without a camera and only appear in the captured image or viewing panel.

Thermal imaging using infrared lights offer real-time feedback of temperatures. Inspectors may opt to use a thermal imaging device with other types of tools to improve accuracy.

For instance, pockets of moisture typically appear hotter, compared to dry locations. This can be picked up by the cameras and infrared LED boat spotlights. In hulls, the build-up of moisture tends to appear between wood, steel, aluminum or fiberglass. On commercial sailboats, pockets of water are common around encased (glass-in) chain plates.

Infrared LED Boat Light Applications

Boat inspections using thermal imaging and infrared devices have numerous on-site applications. In addition to detecting trapped moisture, the equipment can also be used to locate previous repairs and uncover worn out components.

During operation, an infrared LED light (with a thermal camera) may be applied to monitor engines. Such units detect abnormal operating temperatures, which is beneficial in preventing failure from overheating. Infrared LED lights can take on explosion proof construction, for use in flammable work sites, including industrial shipyards and other marine locations.

UV LED Lamp Applications in Commercial Aquariums

In marine locations, ultraviolet UV LED lamp is mostly used for non-invasive disinfection. Specifically, UVC, with a wavelength range of 200-280 nm, is applicable to large-scale sterilization, which can be found in industrial water treatment plants and food processing facilities.

Commercial aquariums also use UVC LED lamps to streamline cleaning inside tanks that hold corals and fish. This article expounds on such applications and provides tips for proper usage.

UV LED Sterilizers

UV LED luminaries inside aquariums are utilized to disinfect the water and surface. The lamps target bacteria, algae and harmful parasites that could cause diseases inside domesticated fish.

There are two types of UV sterilizers for tanks and large chambers: inline and hanging. The main difference between the two options is their mounting mechanisms. An inline UV LED unit is designed to work with the core filtration component of the aquarium. It is installed in the last pass of water, before re-entering the tank.

Next, a hanging type of UV LED fixture for sterilization incorporates a ladder-hook, which allows the unit to be mounted on the back of the chamber. Easy access to the luminary allows for seamless maintenance. Hanging UV LED lamps are low wattage and feature compatibility with small aquariums.

It is important to consider that both types of UV LED sterilizers are supported by a conventional water pump and plumbing components. These parts help circulate water around the tank.

Determining Flow Rates

Maximizing exposure is key to boosting the effectiveness of UV LED lamps inside aquariums. Parasite control requires a slower flow rate, while bacteria and algae can be controlled at a slightly faster flow rate.

These settings should be carefully adjusted, based on the type of organisms inside the chamber. For inline UV LED fixtures, this is done by configuring the ball valve and bypass components.

Integrating LED Lights with Marine Equipment in Boats

Boat owners have very limited space to work with inside vessels. This is an issue for individuals who use different types of marine equipment at sea. Furthermore, boating expeditions that require large amounts of supplies or cargo need to incorporate space-saving features to ensure flexibility and comfort during the trip.

Read on to learn about how such techniques work and their applications in marine environments.

Space-saving Tips for LED Lights on Boats

One of the most effective ways to improve illumination on boats without taking up unnecessary space is through integration. This technique works by installing LED lights with equipment around the boat. For example, individuals may choose to setup LED fixtures inside speakers. This configuration can be used to boost aesthetics on the boat without needing to install a separate lighting system.

When selecting an LED light for boats, one can choose from a wide range of colors and effects. It is important to select a set of colors that will not obstruct or interfere with standard navigation lights, as required by marine regulators.

As a general rule, entertainment lights on vessels should be less powerful than external LED navigation lighting systems. Additionally, non-standard LED fixtures should not be mixed with navigation lamps to reduce confusion on the water.

Boosting Convenience and Safety

LED light integration is useful around frequently used boating equipment. Such components may include the mast, storage bins, seats and more.

LED fixtures can also be installed on boating racks and towers (such as a wake tower). This type of integration is particularly useful for LED spotlights and bars. From such elevated positions, individuals can easily direct light beams on the water.

Lastly, for inaccessible LED lamps mounted on towers or rails, long handles or remote switches should be used to improve light direction and beam manipulation. For more information on boat led lights visit the link here

Reusable LED Lights for Trawling on Commercial Fishing Vessels

Extended boating operations, such as commercial fishing and patrolling, require LED Lights support. The main issue with this need is lack of reliable power sources. Batteries are heavy and can be expensive to maintain a constant supply.

For trawlers, this concern is addressed through the use of glow sticks. The temporary units are secured on or near the hook for visual clarity, allowing marine creatures to see the bait and consume it.

Replacing Glow Sticks with Solar LEDs

For this specific application, relying on glow sticks is an extremely wasteful practice. The lights only last a few hours and are thrown away after use. Fishermen usually throw the flimsy light sources back into the ocean, while pulling lines back in the boat.

Jesse Senko, a biologist at Arizona State University’s School for the Future of Innovation in Society, wants to change this practice, by replacing traditional glow sticks with solar-powered LED lights.

The reason Senko chose solar-powered units is due to its reusability. When he interviewed local fishermen during trials for the lights at sea, boat operators clearly expressed that throw-away batteries are not sufficient for net or trawling lights. Inserting new power cells in demanding and wet conditions can be difficult. Furthermore, it cost money (and space for storing batteries on the boat) to keep the lights operational.

Net Lighting Requirements

In order for the lights to be useful on fishing boats, they have to be able to provide illumination for long periods of time – at least 12 hours. LEDs are perfect for meeting such stringent operational requirements. The lights consume very little energy, compared to incandescent and halogen lamps.

Furthermore, the solid-state luminaries can withstand rough impacts, which on a trawling vessel includes constant banging on the side of the ship, constant pressure, when deployed underwater, and corrosion from surrounding saltwater.




Transitioning from Metal Halide to LEDs for Shipyard Lighting Systems

Shipyard facilities require brilliant illumination inside the building, due to detailed maintenance, repair and restoration tasks that come with operations. Unfortunately, lights do not thrive well in such establishments. Shipyards are extremely humid, corrosive and flammable. Furthermore, the environment is filled with vibration from constant use of heavy-duty equipment. Nowadays, shipbuilding and repair businesses are transitioning from metal halide lamps to LED fixtures, in order to improve illumination inside the facility. This article takes a closer look at Donjon Shipbuilding and Repair’s adoption of boat LED lights.

Addressing Visibility Issues

The 200,000 square-foot shipyard facility boasts 125-foot ceilings to serve 1,000-foot long commercial vessels. Before transitioning to LEDs, the building utilized 266, 1000-watt metal halide fixtures. The high ceilings made the units difficult to reach for periodic ballast maintenance and re-lamping projects, which were frequent due to the rugged environment.

Furthermore, operators used the luminaries around the clock – catering to both daytime and nighttime workers. Starting the metal halide lighting systems took approximately 20 minutes per day. According to a technician working for the company, individuals were forced to use flashlights during work because general lighting was not powerful enough to facilitate accurate readouts on measuring devices.

Transitioning to LEDs

The shipyard business replaced the metal halide lamps with 79 LED fixtures, which surpasses illumination levels of the previous lighting system. Capable of offering 60,000 lumens of white light per unit, the high bay lights are highly energy efficient. Moreover, the LED fixtures are lightweight, streamlining access during installation. The high bay lamps operate on 480V and provide lighting efficiency rates at 115 lumens per watt.

To ensure consistent operation in extreme conditions, the units feature an ambient operating temperature range of -40°F to + 149°F. Overall, the new LED lighting system will come with at least 10 years of zero maintenance.
