How do you illuminate your aquarium correctly?
Unlike in your living room or bathroom you shouldn’t just follow your personal taste when choosing aquarium lighting, since live aquatic plants are involved. For your fish the lighting is less important but aquatic plants have adapted to the existing sunlight in the course of evolution. They use the individual spectral components of visual sunlight to produce energy through the photosynthesis process.
For your plants to thrive, your aquarium light needs a sun-like spectrum. The JBL SOLAR fluorescent tubes and LED light under Lighting precisely have this sun-like light because they are full spectrum lights. Full spectrum means that not only some spectral components but that ALL visible spectral components of the sunlight are created. Plant expert Prof. Dr. Ole Pedersen has found out in tests that the JBL SOLAR full spectrum lighting has the most positive influence on the growth of aquatic plants of all the lamps tested!
What can modern LED lighting do?
The LED technology has revolutionised our lives: long-lasting torches, stylish car headlights, energy-saving room lighting and, of course, natural aquarium lighting. But why has a JBL LED concept taken so long? LEDs have been around for a long time!
Because LEDs have only recently become more energy-saving than fluorescent tubes, there hasn’t been the technology or demand (!) generally to improve the LED light spectrum for aquarium plants. Up to now LEDs were only used in the technical sector and in the home. The light spectrum of aquatic plants, however, varies considerably from the spectrum of household or torch LEDs. Here we are talking about the photosynthetically active radiation range of the light, called PAR (Photosynthetic Active Radiation), and a full spectrum which contains the TOTAL range within the visible light spectrum. Both of these components were needed before we could produce the perfect light for aquarium plants!
Since JBL was the first manufacturer worldwide to develop a full spectrum modelled on sunlight with its JBL SOLAR fluorescent tubes (under Lighting ) our development department didn’t just want to use the available home spectrums for LED aquarium technology, it wanted to create a SOLAR full spectrum, especially for aquariums! This took some time – but now it is available!
How does the amount of light (lux) and the PAR value change under water?
We investigated this interesting question with an equally interesting experiment. In the JBL indoor koi tank we determined all the values with increasing water depth (every 10 cm) while diving with waterproof sensors.
The PAR meter was placed in a waterproof mobile phone case and the sensor head was slowly moved back and forth in the direction of the light at different depths. Elena Hänle, JBL’s chemistry expert, noted the highest PAR value displayed at each depth on the outer pane.
The values were measured directly above the surface (5 cm distance to the JBL LED SOLAR NATUR) and directly below the surface, then at distances of 10 cm, until they reached the bottom of the tank.
In short: The PAR value is always highest when a colour temperature of 4000 K is selected. The illuminance in lux was always measured with a luxmeter at the same time. It is directly related to the PAR value. A colour temperature of 4000 K also gives us the highest lux values because the cool white AND warm white LEDs are on together with this setting.
What are the benefits of the JBL SOLAR range?
With the modern JBL LED SOLAR system you will receive:
JBL LED Solar Natur and Effect with remote control unit
An immediately accessible, elegant LED light system, incl. remote control, with maximum light efficiency for beautiful aquarium plants.
JBL LED Solar Natur
Perfect light for your fish, invertebrates and aquarium plants, since the warm-white and cold-white LEDs are evenly distributed in the light bar (only at JBL!).
Lux measurements compared
An energy-saving aquarium light, since the JBL LED SOLAR provides twice as much light compared to lighting with fluorescent tubes, while simultaneous halving the electricity costs.
Gives you the possibility, with the help of the enclosed remote control, to slowly increase the light levels in increments or to simply switch the light on or off. You can also select one of three set colour temperatures: 2700 K (warm light), 4000 K (daylight - ideal for aquatic plants) or 6700 K (cold-white daylight).
Mounting all required components for the attachment: fits into the existing T5 or T8 fluorescent tube light unit (Both T5 and T8 end cap sizes are included) or position with the telescopic V4A stainless stell holding brackets (also included) on the aquarium rim. Special brackets for suspension from the ceiling are also available as accessories.
Cooling fins prolong the service life
Optimal passive cooling through cooling fins in the lamp body lead to very long service life. The LED module has a service life of more than 50,000 hours. With an illumination time of 10 h/day it lasts for more than 13 years! (The extremely long service life of 50,000 hours applies only to the LED module. The other components are subject to the guarantee: 2 + 2 years)
Ideal PAR value
Specially optimised for aquarium plant growth: ranges of the visible light are used by the plants to produce energy in the photosynthesis process. The quantity of this photosynthetically active spectrum (PAR) can be measured with special devices. With a PAR value of >200* the JBL LED SOLAR Natur provides the perfect light, just as the plants would get from the sun in their natural habitat!
*) measured as PPFD (Photosynthetic Photon Flux Density) in µmol/m2/s in a distance of 20 cm to the light.
A safe system with double effect: watertight in accordance with IP67. If a water ingress were to cause a short circuit, the power supply would switch off automatically.
The changeover to modern LED technology is easy
You can easily exchange your fluorescent bulbs for JBL LED SOLAR lights, even if the original light unit doesn’t work anymore. You only need the holders left and right to attach the JBL LED lights. Here's how it works:
Removing fluorescent tubes
Remove your fluorescent tubes (T5 or T8) from the sockets and measure the tube length without the pins at the ends. In the following table you can find the suitable LED for the appropriate tube length you want to replace.
Selecting JBL LEDs
Start with the basic equipment of the JBL LED technology ( JBL LED SOLAR NATUR ) in the required length stated on the back of the packaging.
Plugging in the adapters
Press the JBL retrofit adapters (included in the kit) onto both ends of the JBL LED light and then into your moisture-proof sockets of the tube holder. Screw them back onto both ends of the tube sockets – finished! The LED lights are freely rotatable and can be precisely aligned into a horizontal position.
Putting light on the aquarium rim
If you don’t want to use the existing fluorescent tube holders you can also put the JBL LED light directly on the aquarium rim with the enclosed V4A stainless steel holding brackets.
Now connect the cable of the LED light with the infrared receiver (enclosed in the kit) and connect the IR receiver with the driver (ballast). The driver has a power plug which you put into a timer or directly into the power socket.
Putting remote control into operation
With the enclosed remote control you can now switch the LED light on and off or slowly switch it up and down. With the remote control you can also choose between three light colours. The buttons for the colours Red (R), Green (G) and Blue (B) are only relevant if you extend your basic equipment with a JBL LED SOLAR EFFECT light.
Get the most out of LED light technology
Would you like to exactly reproduce the light of a tropical living environment (biotope)?
With the accessory JBL LED SOLAR CONTROL you have the opportunity to imitate the light conditions of a habitat exactly, with dry and rainy seasons or lightning storms, or to set the perfect light for a densely planted aquascaping aquarium. The JBL development team has implemented 5 aquarium types with the JBL LED SOLAR CONTROL :
