What does CCT (correlated colour temperature) MEAN?

Correlated color temperature
 
In order to differentiate the various hues of white, artificial light sources like LED lightbulbs are labeled with a correlated color temperature, or CCT.

Lighting color is measured in Degrees Kelvin, with different temperatures providing different colored light. LED lights with lower Kelvins appear warm, like candlelight or incandescent lamps. Neutral daylight-like LEDs are 4000-5000K. LED bollard lights in the 6000-7000K range cast their surroundings in a cold, icy blue.

As the lighting color most similar to daylight, neutral light is the most common LED light option. Warm light creates a softer ambience and is often used in landscaping and decorative applications. It offers the advantage of more effectively conserving power than other colors, as cooler temperature lights are more efficient than warmer ones

Frequently Asked Questions

A solar light is one that captures the sun's rays and stores them to power the light when it becomes dark. Seems easy enough, right? and it is.

Solar-powered lighting consists of a solar panel or photovoltaic cell that collects the sun’s energy by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity that is stored in a rechargeable battery.

Other components include an intelligent controller that prevents the solar panel from overcharging the battery. Once the sun goes down the controller senses that no more energy is being gathered so it automatically turns on the LED light and viola, you have light that is using energy from the sun.

LED lights, or light emitting diodes will emit that light in an efficient controlled way. They also have a long life, meaning you won't be replacing your solar lights any time soon.

So, we know what solar lights are and how they work, but how are they beneficial? For starters they are totally green. This means environmentally friendly because they don't need to be plugged in, they aren't draining our electricity and they are not emitting any harmful gasses back into the atmosphere. In other words, they are clean energy.

Each day the energy stored in the battery is renewed by the sun. Our Solar lights simply go about their business of recycling the sun's energy day after day, even when the sun isn't shining directly onto them. Once it gets dark they come on, each and every night. They are reliable and easy to install.

Solar lights are stand alone. They can be used anywhere and everywhere from gardens to docks and from boats to walkways.

Solar lights are a unique way and functional way to light your pathways, roads, parks and gardens or just about anywhere, they come in many applications and many shapes and sizes, but they all do the same thing, use a renewable resource to power themselves. Solar is a fantastic way to light our way.

  • 100 lux – This level of light is sufficient for lifts, corridors and stairs. Areas that are transitory for occupants and don’t require any detailed work. Warehouse areas and bulk stores will also require this minimal light level. You wouldn’t want to read a book in this sort of light, but it is good enough to get around without injuring yourself and see where you are going.
  • 150 lux – Restrooms and plant rooms require this level of light. Again this is not particularly bright but good enough for simple tasks.
  • 200 lux – Entrance areas and lobbies require this level of light, and it is also the minimum for a restaurant dining area.
  • 300 lux – Assembly Areas, like village halls require at least 300 lux
  • 500 lux – Retail spaces should have this as a minimum light level, as should general office spaces. This level should be suitable for prolonged work on computers, machinery and reading.
  • More than 500 lux – If you have an area where intricate work is being carried out, then very high lux values may be needed. Where fine detailed work is being carried out, anything up to 2,000 lux can be used – this is usually only necessary in fairly unusual circumstances. For most purposes, 500 lux will be ample.

The lux (symbol: lx) is the standard unit of illuminance and luminous emittance, measuring luminous flux per unit area. It is equal to one lumen per square metre. In photometry (the science of measuring light), this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface

The lumen (symbol: lm) is the standard derived unit of luminous flux, a measure of the total quantity of visible light emitted by a source. Lumens are related to lux in that one lux is one lumen per square meter.

Basically, the higher the number of lumens a light source emits, the brighter it is.

In simple terms, Lumens are a measure of the total amount of visible light from a lamp or light source. The higher the lumen rating, the “brighter” the lamp will appear.

Familiar examples

  • A typical 4 x D cell battery Maglite will emit approx. 70 lumens
  • The average hardware shop path light using 2-3 LEDs emits 15-18 lumens
  • A 25W incandescent globe emits approximately 160 lumens

Can’t tell the difference between the black and navy colored socks in your walk in closet? Could be that your current lighting source has a very low CRI! Not all light is made equal; some LED's renders color better than others. Color Rendering Index (CRI) is the measurement of how colors look under a light source when compared with sunlight. The index is measured from 0-100, with a perfect 100 indicating that colors under the light source appear the same as they would under natural sunlight.

Lumen output varies by product. Please view the product specification on each light or download the individual product Data Sheet on relevant web page

Yes, our solar lights charge on cloudy days. During daylight, even when overcast, the solar panels continue to charge the batteries, and on a full charge the system is designed to work for at least three days with no sun.

Yes, the standard operating profile will operate dusk to dawn on a four-hour charge. Fully charged they will operate dusk to dawn for up to three nights with no additional charge.

All Eco Solar Lights use lithium Ion or LifePo4 batteries as their energy storage device. They are a cost effective, environmentally responsible way to add long lasting brightness and beauty to your evening landscape while increasing safety.

The advantages of using rechargeable lithium ion batteries as opposed to typical rechargeable lead acid batteries are as follows: 

Chargeability 

Where lead acid batteries can be charged and discharged approx. 1,000 times a lithium ion battery can be charged and discharged approx. 5,000 times

Superior “Useable” Capacity. 

Unlike with lead acid batteries, it is considered practical to regularly use 85% or more of the rated capacity of a lithium ion battery bank, and occasionally more

Fast & Efficient Charging. 

Lithium ion batteries can be “fast” charged to 100% of capacity. Unlike lead acid, there is no need for an absorption phase to get the final 20% stored. If you experience several partly cloudy days with your solar light lithium batteries have no problem being topped off before the sun goes down. With lithium ion batteries you can charge up what you can and not fret about leaving your battery bank perpetually undercharged

Very Little Wasted Energy. 

Lead acid batteries are less efficient at storing power than lithium ion batteries. Lithium batteries charge at nearly 100% efficiency, compared to the 85% efficiency of most lead acid batteries.

Climate Resistance. 

Lithium ion batteries are much more efficient at low temperatures. For harsh environments (hot and cold), Lithium-Ion batteries have a technological advantage

Little Maintenance Requirements. 

Lithium Ion batteries are very virtually maintenance free.

Size & Weight Advantages.

Lithium ion batteries are as much as 77% smaller in dimension and 194% lighter than the equivalent lead acid battery

We recommend a a first charge (after unpacking) of between 10 - 12 hours in full direct sunlight. Recharge after providing  a night of light is between 4 - 6 hours.

The LED’s and solar panel will last longer than the battery, so it does not make sense to have to replace the whole unit when the battery finally dies. Replacement batteries are available from us

To properly look after and maintain your battery, it is recommended that the battery be charged and discharged monthly.

Although lithium-ion batteries are non-toxic, it's still important to recycle them appropriately. Recycling centres that accept lithium-ion batteries are common and easy to find in Australia. These centres typically disassemble the batteries in a manner that completely prevents any harm to the environment. Once disassembled, the individual parts and materials are then recycled and reassembled into new materials. Contact your local recycling centre for more information or alternatively return them to us and we will deliver then to our local recycling centre

Outdoor solar lights come with an on/off switch so you can control when you want your solar light to turn on. If you want the outdoor solar light to continue to work all day every day, you can simply leave the on/off switch in the on position. If you want to charge the outdoor solar light and use the light at a later time (such as a weekend party), you can turn the on/off switch to off until you are ready to use it. When the switch is in the off position, the light will continue to receive electricity from the sun and store it for later use.

First, check to make sure the on/off switch is in the on position. Second, make sure another light source isn’t preventing the light from turning it on. Move your outdoor solar light to a darker location and see if the light comes on. If it still doesn’t illuminate, check to make sure the batteries are fully charged. Move the solar panel to another spot during the day to see if it will receive more sunlight. Note: The batteries included with your solar light will need to be replaced when their charging ability is decreased. They should be replaced approximately every five years.

Eco solar lights solar lighting is virtually maintenance free, since the batteries require no regular service, the LED’s have an expected life span exceeding 50,000 hours. Simply wipe over the panel every now and again with a wet cloth.

Each component of a ecosolarlights.com solar light has a different manufacturer expected lifespan:

  • Solar panels: up to 20 years
  • Batteries: approx. 5 years
  • LED fixtures: exceeding 50,000 hours
