When is the Best Time to Buy LEDs

There are several factors to consider when transitioning from incandescent or halogen fixtures to LEDs. Cost, compatibility and performance are aspects that are important to get right, for a successful transition.Focusing on the first factor, many people want to buy LEDs but are concerned about the initial, high upfront cost. Read on to learn more about how LED prices could shift in the next few years.

Price and Timing

According to a new study published in Environmental Research Letters (Replacement policy of residential lighting optimized for cost, energy, and greenhouse gas emissions), the reason for transitioning to sustainable LED fixtures may determine the ideal time to make the move.

Researchers applied life cycle optimization frameworks to build a model for the study. The results of the trials showed that individuals who are concerned about high CO2 emissions and saving the environment should transition to LEDs as soon as possible.

However, people who are more interested in reducing their energy consumption and decreasing their monthly energy bill at home, should wait a bit longer.

But is this really the best option to take for people who want to decrease energy use at home?

Immediate Energy Savings

The authors of the study cited that LED Lights tech will go through rapid development in the next three years, between 2017 and 2020. This will affect its performance (increase), as well as its price (decrease).

With this in mind, this three-year window (and beyond) is an optimal period to buy LEDs.

Furthermore, LEDs offer immediate savings after installation, through reduced energy use, which will accelerate one’s return on investment (ROI). The modern, solid-state fixtures also last longer than traditional lighting technologies (the units come with a lifespan of 50,000+ hours), which could decrease replacement costs, from a long-term perspective.

Using LEDs to Transmit Wireless Data with Li-Fi

The Internet-of-Things (IoT) sector will revolutionize lighting systems by incorporating wireless features and sensors for network-based or automated operation. LEDs, with their energy efficient features and solid-state builds, is also set to become the lighting technology of choice around the same time the IoT industry hits mainstream.

Can LEDs help bridge the gap between the demand for wireless data transmission and IoT networks? Find out below.

LEDs and Li-Fi

Li-Fi, which uses light instead of radio frequencies (used by traditional Wi-Fi), was first introduced in 2011 at the University of Edinburgh, as an alternative to Wi-Fi. The protocol uses rapidly flickering light from a single LED to transmit data wirelessly. Called Visible Light Communication (VLC), Li-Fi leverages frequencies in the range of 400 and 800 terahertz.

The best way to visualize how Li-Fi works is by comparing it with light-based Morse Code. The diodes toggle at rapid speeds (undetectable by humans). This process, which is called on-off keying, facilitates the transmission of binary code to a receiving device. An alternative VLC method includes continuous signaling.

Combining Illumination with Wireless Data Transmission

Interestingly, according to researchers from the University of Edinburgh, LED fixtures can be used to light up a room and transmit wireless data simultaneously, without affecting illumination. Both VLC techniques mentioned above does not degrade LED performance (no dimming or color shifting).

The lifespan of the LED is also retained at 50,000+ hours. However, it is critical to highlight that such processes can contribute to a slight increase in operating temperature experienced by the luminary.

According to a recently published study (Perovskite Nanocrystals as a Color Converter for Visible Light Communication), scientists are incorporating a nanocrystalline structure (derivative of cesium lead bromide and nitride phosphor) in order to increase bandwidth capacity. As a result, data speeds of 2 Gbps and a bandwidth of 500 megahertz can be achieved.

omni-directional leds

Directional vs Omni-Directional LEDs

Traditionally, LEDs are directional light sources. Taking on a standard chip configuration, the diodes project beams at roughly 180-230 degrees. By comparison, incandescent and conventional bulbs offer omni-directional LEDs illumination, emitting beams between 270-360 degrees.

When choosing between the two designs, it is important to understand how the two options handle illumination.

Directional Lighting and Detailed Tasks

With a tighter spread, directional light sources provide more control over the positioning of the beams during illumination. This makes the configuration ideal for task, recessed and display lighting. Directional bulbs do not utilize reflectors to push the light towards the target area. As a result, less light is wasted during operation.

The proliferation of LED technology strongly relies on healthy consumer adoption rates. Since most individuals and businesses are used to omni-directional light sources (incandescent bulbs, fluorescent tubes and metal halide lamps), lighting manufacturers were forced to release innovative solutions for LEDs to meet such requirements. Specifically, engineers added reflectors and new designs that extend the angle of the beams, making them wider.

To ensure consistent performance, today’s lighting manufacturers trade in epoxy for silicone for robust thermal management. Silicone can withstand temperatures up to 200 degrees Celsius, while epoxy starts breaking down at 80 degrees Celsius.

Omni-directional LEDs Illumination and General Spaces

Omni-directional LEDs are suitable for wide-area lighting and outdoor locations. In order to get the most out of this type of light, it should be installed over large spaces, with minimal obstructions. Capping the light (without a reflector) would waste the stray beams, causing a significant loss in brightness. Lamps that require full, 360-degree illumination, such as strobe or emergency lights, can directly benefit from omni-directional lighting.

To suit omni-directional lighting preferences, LED bulbs typically incorporate a series of diodes, pointing at different directions. Initially patented under US patent number 5594433 such luminaries also use convex reflectors to promote even distribution.

Top UV LED Applications

Top UV LED Applications

Ultraviolet (UV) LEDs are unique lamps that emit light within a range of 10 nm and 400 nm. At this rate, the bands are invisible and undetectable without special machines.

These days, there are plenty of uses for UV LEDs in industrial operations. For example, in commercial paint spray booths, explosion proof UV lamps are crucial components for paint curing. The lights help streamline the final stages of curing, for a speedy, thorough finish of coatings.

Read on to learn about other UV LED Applications!

Top 5 UV LED Applications:

  1. Food/Air (HVAC) Sanitation: UV LED lamps that emit UV-C bands are capable of non-invasive disinfection. Food manufacturing plants use such lighting systems to clean vegetables and other products before packaging. Interestingly, UV luminaries can also be installed inside HVAC systems, elevators and vents to promote clear airflow.
  2. Currency Verification: Law enforcement groups use handheld UV lights to verify the legitimacy of banknotes. Exposure to UV bands cause certain components inside bills, such as embedded stripes, to glow or turn different colors. Such techniques are also applicable to artwork inspection. Curators may shine UV light over paintings to check for inconsistencies, repairs and hidden elements (overpainting or the use of new inks).
  3. Mineral Detection: In mining, operators apply UV lighting systems to uncover precious stones and minerals. This method is safe and non-invasive, since it does not require workers to dig into the ground. Flashing the lamp over the location allows chemicals in gemstones to react to the light. Explosion proof (for safety) and short-wave UV bands are most effective for such operations.
  4. Crime Scene Analysis and Inspection: Forensic specialists and scientists commonly use UV flashlights to investigate crime scenes and evidence. Blood, urine and saliva all react to UV bands, which can be easier to detect in small amounts.
  5. Crowd Control: Businesses, concerts and other events can use UV light to verify tickets and bracelets at various entry points of the location. This is considered to be much faster than checking registration numbers. Workers at the event can also monitor beverages using handheld UV lights.

boat dock lights

Types of Boat Dock Lights

Keeping boat docks safe starts with illumination. With adequate boat dock lights you can keep the location secure, discouraging criminals for tampering with valuable items on your boat. From a safety perspective, you can move around the dock and vessel freely with more confidence.

Keep reading to learn about the different types of LED lights for boat docks.

Configurations and Concerns

Boat dock lighting systems must be able to withstand rough treatment and unpredictable conditions. Because of this, it is important to make sure the LED light is waterproof and (ideally) corrosion resistant. When it comes to size, the units should be compact or low profile. This is because there isn’t a lot of space on boat docks. Lights that are bulky or intrusive could expose individuals who aren’t familiar with the placement of the units to accidents.

In some cases, the dock is so tight that installing LED lights on the actual walkway is not possible. For such concerns, it would be a good idea to install marine lighting systems under the dock, with the light shining outwards on the water. If the light is bright enough, the beams should reflect off nearby surfaces or the water, providing indirect illumination.

Types of Boat Dock Lights

Slim pendant lights that provide 180 degrees of light are ideal for just about any type of lighting configuration on boat docks. They can be installed along the floor boundaries and corners or wall mounted on the side of the dock. Another option includes LED strip lights. The units are extremely slim and are ideal for locations with limited space. They can also be equipped with an in-line transformer for low voltage requirements. Moreover, due to their thin design, people are less likely to trip or slip on them.

Lastly, for a traditional approach, one could setup a pole-mounted lighting system at the intersections of boat docks. This option is reliable but can be costly, as it requires investing in a sturdy pole and other electrical components.

LED Underwater Boat Lights

LED Underwater Boat Lights have numerous applications. Unlike other lighting technologies, such as incandescent and fluorescent lamps, LEDs take on solid-state designs that allow the units to withstand the effects pressure in underwater environments.

As a result, this makes the luminaries incredibly useful for a myriad of marine-related tasks. This article explores such applications, which shows just how far you can push these heavy-duty lights during operation.

Exploration, Repair and Safety

LEDs are being used for illumination during exploratory projects and research. With the use of custom light engines and drivers, some groups have taken LED boat lights to great depths at 20,000 pounds per square inch. Furthermore, the lights are compact, making them easy to install on underwater vessels and machines.

On offshore oil rigs and drilling platforms, LED Underwater Boat Lights are ideal lighting systems for repair work and operations. Equipped with corrosion resistant and waterproof builds, the units can withstand immersion in harsh environments during underwater welding, pipe installations and equipment teardown.

When it comes to safety, LEDs are being applied to monitor underwater oil wells, pipes and costly equipment. Submersible LED boat lights with high color temperature ratings help improve detection, as well as equipment failure in seabeds, where conditions are often cold and dark.

Wash-down and Cleaning

Marine vessels and equipment need to be cleaned on a regular basis to prevent corrosion-related damage. While such tasks are not conducted underwater, lights used during cleaning and wash-down sessions are still exposed to large amounts of harsh liquids and oils. Again, LED boat lights with industrial-grade builds are perfect for illumination during such tasks.

They can be mounted on carts for added stability and control. Moreover, magnetic mounts for portable variants allow operators to quickly attach lights on compatible surfaces with ease. Illumination from powerful LED lights also help workers uncover inconsistencies on surfaces of vessels, greatly improving safety and reducing operational risks. Catching these issues before they become full-blown is critical to preventing accidents in the workplace.

vapor proof boat light

The Benefits of Vapor Proof Boat Lights

LED boat lights are prone to a plethora of corrosive substances out in the water. Because of this, lighting manufacturers have designed Vapor Proof Boat Lights that are corrosion resistant and waterproof. But what about damage caused by moisture and vapors? What can be done to protect marine luminaries from such destructive elements? Find out below.

Vapor Proof 101

Wet atmospheres can wreak havoc on standard lighting systems. The presence of moisture could trigger chemical reactions that breakdown surfaces and wire coatings. To ensure protection in wet environments, such as boat docks, ship yards and industrial sites, luminaries with vapor proof features must be used in the location.

Vapor proof lights are constructed differently, compared to standard lights from mainstream hardware stores. The socket and wiring are protected from moisture, fumes, dust and rain. In other words, the critical components of the fixtures are sealed to prevent unwanted contaminants from entering. Traditionally, the lamps are housed in thick glass, which reinforces its sturdiness in marine or wet locations.

It is important to consider that vapor proof lights can help boats and businesses maintain consistent power usage, resulting in long-term operational reliability and savings. Damaged lights have a tendency to consume large amounts of power over time. By protecting the internal components of lights via vapor proof designs, they can operate optimally without meticulous maintenance.

Do I Really Need Vapor Proof Boat Lights?

The question that most boaters have is whether or not vapor proof lights are really important for marine lighting systems. For rugged marine sites, the answer is yes. For example, vessels that are used for dock cleaning projects can benefit from vapor proof lighting. In addition to preventing saltwater corrosion, the extra layer of protection prevents the buildup of moisture caused by steam jets, which can carry aggressive chemicals from cleaning solutions.

For mainstream, consumer boat lights and locations, vapor proof luminaries are not vital to maintaining illumination. However, this does not mean that you can’t use them. Vapor proof units are used in car washes, processing plants, parking lots, warehouses, swimming pools, kitchens and auto repair shops. They come with numerous applications outside of boats and marine locations.

With that being said, it’s common for boaters to use vapor proof lighting for peace of mind. If you’re constantly replacing your lamps due to the presence of a range of destructive elements that go beyond water, such as dust and harmful fumes, vapor proof lighting might be what you need.

colored led boat light

White vs Colored Led Boat Lights

Choosing between white and colored led boat lights can greatly affect your experience on the water. The two options vary in applications, from safety lighting to personal preference. Most consumers are not aware of such benefits, which limits the lighting system’s integration with their boating activities.

colored led boat light

White LED Boat Lights

White LED lights are the most common luminaries found in boats. They only emit one color and are mainly used for clean aesthetic designs and mid-to-long range viewing. Moreover, the units can be used to focus on specific targets in the water. White LEDs come with extended lifespans of up to 50,000+ hours and feature sturdy, solid state construction. They are extremely compact and are ideal for lighting up docks, ladders, stairs and the frame of vessels via strip lighting systems.

 

White LED units for boats come in a range of color temperatures. At the low end of the scale, one can find warm white light, which resembles yellowish light coming from an incandescent light source or natural candle. As you go up the scale, light turns from dark yellow to sharp white. LEDs with high color temperatures come with a bluish white color. For bright illumination, white LED boat lights with high color temperatures are the way to go. They are also safe for use in dark waters, when indirect, passive lighting from docks, roads and city lights are unavailable.

Colored LED Boat Lights

Colored LED boat lights are capable of emitting up to 16 million different color combinations. The units offer the same extended lifespan benefits and solid state construction as white LEDs. However, they come with more operating components, such as remote controllers and components that allow the luminary to shift colors. Using red, blue and green colors, the lights are able to light up a boat with an array of dazzling combinations.

Aesthetically, colored LED lights can make a boat stand out from other vessels at the dock. For anglers, some use green lights to attract large fish at night. This practice is mostly applied to spotlights and submersible units. RGB boat lights can also be used to comply with certain regulations at sea. Referred to as navigation lighting, the units serve as early warning systems for other vessels in the area.

To conclude, choosing between white and colored LED boat lights highly depends on how the luminaries will be used on the boat. To prevent premature failure during operation, don’t forget to make sure the units are waterproof and corrosion resistant.  To learn more about Boat Lights visit Larson Electronics LED Boat Lighting.
