LED Spa Pool Light/LED Underwater Light
LED Spa Light Underwater LED Pool Lights LED Float lights
LED Pool lighting technology has come a long long way in the last 5 years.
In fact LED lights are revolutionising all lighting applications including swimming pools.
LED pool lights use up to less 80% less energy, are still very bright, can change colors, and last a lot longer than typical pool lights.
LED Light refers to a type of lighting that utilizes Light-Emitting Diodes (LEDs) as sources of illumination, rather than electrical filaments or gas.
Unlike traditional lighting, however, LED lights create visible light with reduced heat generation or parasitic energy dissipation. In addition,
its solid-state nature provides for greater resistance to shock, vibration, and wear, thereby increasing its lifespan significantly.
LED pool lights use up to less 80% less energy, are still very bright, can change colors, and last a lot longer than typical pool lights.
Color changing LED pool lights are programmed with a set of lighting modes that completely transform the environment on your pool area.
We have several RGB LED controller for choosing, say WIFI LED controller, DMX512 LED Controller, 2 Wires Remote controller, 4 Wires Remote controller,
Switch and Remote controller.
The Inground Pool Light/LED Spa Light:
The unique, high quality stainless steel and ABS, PC engineering plastics as the lamp housing makes it perfect for vinyl-liner and concrete pools.
LED Pool lighting is revolutionising the way we light our pools and spa– and, indeed, the entire art of pool lighting.
But what are they, how do they work and, most importantly of all, what do they cost? Want to know more? Read on…
What are LEDs?
LED stands for “light-emitting diode”. As pool lights, they emit a rich and warm quality of light that not only illuminates your pool much,
much more effectively than halogen lights – they do so at a fraction of the energy consumption and, therefore, at a fraction of the running costs:
around, if not more than, 4/5th of the costs!
That’s because they work differently, both in terms of light and heat output.
LED Light Output:
Incandescent lights work by using electricity to heat a tungsten filament that glows when white hot, and emits light in a 360? arc.
However, 90% of the energy is emitted as heat rather than as light.
Halogen lights operate on a similar principal, except that the filament is encased in a quartz envelope that is filled with halogen gas.
The net result is that halogen lights are able to run at far higher temperatures and produce more light for less power.
LEDs, however, work entirely differently. LEDs don’t have a filament.
Instead, light is produced as a result of electrons being passed by an electrical current through a semiconductor.
Unlike regular incandescent or halogen bulbs, LED’s don’t emit light in a 360? arc – instead they emit light in a specific direction.
LED Heat Output
Unlike regular lights, LED’s do not get particularly hot. That doesn’t mean, though, that they don’t produce heat – it’s because,
just like the light they emit, they produce heat in a specific direction. As a result of the directional nature of the heat,
LEDs are equipped with heat absorbers called “heat sinks” that remove the heat and prevent the LED from ever burning out.
Indeed, rather than “burning out” like traditional filament-driven lights, LEDs merely become (very, very slowly) progressively dimmer – or,
to use the technical terminology, they undergo “lumen depreciation”. The practical upshot is that LED pool lights can keep working for north of 30 years – in practical terms, although the LEDs themselves are likely to outlive any other part of the lighting system, other parts of the light will more than likely fail first.
LED Colours
Unlike traditional pool lights, LEDs come in a wide variety of different colours and hues –
colours and hues that can be changed by the flick of a switch, or pre-programmed, or be controlled via a smart phone app.
Having said that, however (and just in case your physics teacher is reading this), LED light is only actually emitted in four colors:
red, green, blue, or amber. Different colors, shades, and hues are created by combining these colors: especially the red, green, and blue combination.
Also, although it is perfectly possible to install white LED lights, there is actually no such thing as “white” LED light.
White LED light is created by either combining blue, green, and red LED light, or by putting a yellow phosphorous coating on top of blue LED light.
If you’re looking to light your pool in different colours,
it’s important to be aware that the wavelengths of different coloured lights react differently when underwater.
Green light, for example, travels through water at 3 times the speed of red light; blue light travels 5 times faster than red light.
The result is that green and blue lights appear, respectively, 3 and 5 times brighter than red lights.
How Much do LED’s Cost?
1. Purchase Costs
The price per fixture of an LED light will run between $20 and $100. The difference in price will depend upon the quality of the product.
LED lights can vary in terms of the colour they produce from anything up to a 15% variance from the ideal specific colour wavelength.
LEDs are priced, therefore, according to the variation from the ideal: the more expensive, the closer to the ideal.
In real world terms, this only really starts to matter when you are using multiple lights in your pool.
If you have multiple lights, you’ll notice if some of them are emitting slightly different shades of light since
the wavelengths coming from each of them will vary. For an average 8.5 x 4.4 metre pool, however, it’s not such a big deal –
especially if you’re pool is rectangular and you can get away with using just one light.
Additionally, price will be determined by the material used in the light mountings.
LED pool lights are protected by heatsink that prevent water from leaking in. Plastic heatsink are cheaper than stainless steel mountings –
but may be less durable over time, and may look less visually appealing.
The price will also be driven by the technological efficiency of the LED. Advanced LEDs produce a significantly higher light output for less energy.
So how do you know what you’re buying? How do you tell the difference? Not by wattage.
With old-fashioned halogen lights, twice the wattage means twice the brightness.
With LEDs, however, what you want to be looking for is the Luminous Efficacy –
the technological term for how many lumens of light are produced by 1 watt of energy: the greater the Luminous Efficacy,
the greater the brightness and the greater the fuel efficiency.
2. Installation Costs
The cost of installing an LED pool light can vary between $200-$700 depending on whether
you’re looking to do a simple retrograde installation of existing lights or something much more elaborate.
3. Running costs
The running costs are where LED’s really score economically. Assuming an average kilowatt per hour price of $0.27 including GST,
a single LED pool light costs around 1/2 a cent an hour to run.
So, in terms of annual running costs, presuming you light your pool for 6 hours a day, 7 days a week, for 6 months of the year,
at an average kilowatt/hour price of $0.27, a single LED pool light will cost you $5.90 per year.
Since LEDs are 3-5 times more energy efficient than conventional halogen lights,
a 20 watt LED light will emit the same amount of light as a 100 watt halogen bulb.
Comparing the running costs of a single LED to those of a single halogen, therefore,
on the same basis of 6 hours a day/7 days a week/6 months a year, a single halogen would cost you $23.58 per year.
You will, therefore, need to engage the services of a licensed electrician to install your lighting.
