LED Lights
LED Light Applications
Many LEDs lights can replace halogen light bulbs without any modifications. These use 12 volt and so they can also be fitted in caravans and boats where 12V battery systems provide power. These are also suitable for use in 12V solar panel lighting systems. They use approximately 10% of the power consumed by halogen lights and about 40% of the power used by CFL lights. They do not get hot like halogen bulbs and will never burn out as they are solid state devices and so are not a fire hazard.
Consider using LED lights and lamps for caravan and RV interior and exterior lighting when camping and travelling, and just add a small solar panel and battery and you have low cost solar lighting system.
Led Lights for Boat and Caravan Lighting and Portable Camping Lights
The LED lights and lamps featured here provide excellent lighting, approximately ten times the light output of similar wattage halogen lights. They can be used in any application where a 12 volt or 24 volt DC power supply is available. When used with our portable solar panels they are a powerful, low power consumption alternative to conventional lighting. The great advantage of using LED lights, apart from their low power use, is their durability and toughness, they are not not fragile like standard light globes and halogen filaments.
21st Century Technology
The LED light components, casings and reflectors used are the most technically advanced available today, including the latest technology multi-voltage circuitry , they can be powered by a DC power supply from 10 volts to 30 volts, so they are well suited for remote and portable solar powered systems.
Waterproof, Shockproof and Rustproof LED lights
The LED dome lights can even be used on off-road vehicles, caravans and mobile homes because they are vibration and shock proof and fully waterproof for use as marine and boating lights, They can even be installed underwater because they are fully submersible. The LED Lamps are manufactured from durable ABS plastic and have stainless steel fittings so they are rustproof as well.
Interior/Exterior LED Lights
The interior and exterior dome lights for boat cabins and caravans have a 120°beam spread that will illuminate an area about 10 meters wide. They are available in warm white and cool white and also with a combination of red and white LEDs. Some are fitted with a switch to select on/off and red or white light. Red light is used for lighting where a white light might impede night vision, such as when driving or navigating a boat.
5 Year Warranty
Most units are sold with a 5 year warranty to highlight their reliability, these truly are LED lights for tough conditions.
These high luminance LED lights are well suited for solar lighting and we assemble solar lighting kits to your custom needs too, so contact us to discuss your requirements.
How to evaluate LED Lights
LED lights compared to other types of lighting
Most of us understand how bright a light bulb will be by it's watts rating, we know a 100 watt incandescent (old type) light bulb will be bright enough to use in the kitchen or shed.
We also know that a 25 watt CFL (Compact Fluorescent Light) is as bright as a 100 watt incandescent because the CFL uses less electricity to produce the same brightness.
Some of the newer technology incandescent halogen lamps are more efficient, a 70 watt halogen will have the same brightness as the 100 watt incandescent, but still be less efficient than the CFL because all incandescent lights waste a lot of power is as heat.
Measuring light quantity - Lumens
Although watts are usually used to indicate a light's brightness, in actual fact they are a measurement of the electrical power used.
The proper term to describe the amount of illumination filling a space is the Lumen, with the 3 light bulbs mentioned before all producing about 1300 lumens.
In terms of efficiency the incandescent is least efficient at 13 lumens per watt, next is the halogen at 18.5 Lm/watt and most efficient is the CFL at 52 Lm/watt.
These three types of light can be directly compared because they shine in all directions as a sphere radiating outward from the source.
LEDs are also categorised by their lumens output and their efficiency is calculated as lumens per watt of power consumed.
But knowing how many lumens an LED light produces is not enough information when selecting one because its light is not the same, it does not radiate a sphere of light in all directions, just in one direction.
How LEDs produce light
LED lights are different because they produce light directly from electricity. Their light is made up of photons that are emitted from the flat top surface of the LED (light emitting diode).
High brightness LEDs emit photons in such great quantities that a powerful beam of light shines directly outward from the surface. The fact that light only shines directly outward from the diode's surface is the main drawback because it only provides light directly in front of the LED.
Therefore optical lenses are used to spread the light out.
For instance, a 100 lumens LED with a beam spread of 80°will spread its light evenly in a cone-shaped beam of light spreading 40°to either side of the beam's center point.
An equally powerful 100 lumens light, but with a beam spread of 150° (the widest beams currently available) will have its light spreading 75° on either side of the beam center.
So we can see that both lights produce 100 lumens of light but the degree of beam spread will determine how bright each light will be.
Therefore we need to measure the light brilliance or intensity to show how they differ in brightness.
Measuring light intensity - Candela
Lumens (Lm) represent the total light emitted while Candelas (Cd), and millicandelas (mcd) correspond to the light intensity.
Referring back to the two 100 lumen LED lights with the different beam spreads, we can measure their light intensities with a light meter to find the narrow 80° beam has an average intensity of 68 candelas (68000 mCd) while the broader 150°beam has an average intensity of only 21.5 Cd.
This shows that while both lights have the same total light power in lumens, the narrow beam is concentrated into a smaller area of high brilliance while the broader beam is less brilliant but will illuminates a larger area.
LED light colour
There is another variable called light colour that needs to be understood.
LEDs don't produce natural white light so they use yellow phosphors, chemicals that glow, to produce white light from blue LED light.
Different shades of white are produced, from cool white which is a bluish white to warm white which is yellowish white.
LEDs are the most efficient producers of light.
Their directional beam is more efficient because the light is not wasted by illuminating areas where it not needed.
The greatest need for LED lighting is as a replacement for the old fashioned light bulbs but the directionality of the beam is restrictive so multi-LED units are produced to simulate conventional 360 degree lighting.
LEDs are used in LED lamps and torches where they can produce very bright light with very low power consumption.
LED torches are usually rated according the the spot brightness in millicandelas (mcd) to indicate the brightness of the beam, while Lights for area illumination are rated in lumens for a given beam spread to indicate how much total lighting is produced.
High brightness LED lights can be used for many purposes, they are often used for solar powered lights as they consume very little power.
