Product information

Light as energy source
Plants provide the aquarium with the oxygen vital for the aquarium dwellers. Plants prevent algae growth, remove pollutants, provide hiding places and reduce pathogens. The right full-spectrum light is important to achieve full photosynthesis.

Easy to install
Insert the fluorescent T8 tube socket into the fixture and turn until the tube locks into place.

Nature as a model
With its light colour and its spectral distribution of the light the tube meets with 9000 K the needs of the plants. It supports their growth and their photosynthetic performance. The light, equivalent to sunlight, inhibits the growth of algae. The light with the colouring render index 1 A means plants and fish present themselves in their natural beauty.

The full daylight spectrum
JBL full-spectrum tubes create light conditions modelled on nature and reproduce a balanced natural lighting. Tested by the IFM-Geomar Leibnitz-Institut für Meereswissenschaften and rated as very good and “Comparable to natural sunlight”. With energy efficiency class B the tube is particularly energy-efficient. Correlation between light spectrum and light intensity: To create a very light tube you only have to intensify the yellow-green spectral range. Adding a little more red and blue will prevent the light from looking too yellow. That’s how it is done with most tubes! However, we don’t want to illuminate a living room but a planted aquarium with different demands, including ALL the spectral ranges of visible light (rainbow colours) to promote perfect growth. That’s why JBL has designed “full-spectrum tubes”, which include all the spectral ranges with NOTHING missing. In return they are slightly less light than other fluorescent tubes. The output of a tube is always 100%, but it is important to know which spectral ranges they cover!

FAQ
JBL Solar tubes: My two new tubes don't "glow". Is that due to a production error?

We can exclude the possibility of a production error. If a light doesn't turn on, that is an unfortunate exception.
If you have a light bar with conventional electronic ballasts, I would recommend changing the starters once to see if they are causing the problem. Does the defective tube glow when you change the tubes on the light bar ? And the other one doesn't ? Then there is a defect in the light bar.

What do the hours of service life indicated for the fluorescent tubes mean ?

Our tubes are not tri-band tubes, but instead, are modern full-spectrum tubes.

If there is a loss of luminance, the operating conditions must definitely be checked. T8 tubes have the longest service life with the least losses at 25 °C ambient temperature, whereas the T5 tubes have the lowest at 35 °C ambient temperature. Most of the closed covers have ambient temperatures that are higher than 25 °C. Generalising data of 8,000 or 10,000 hours of service life should generally be treated with caution, as this data applies to optimised operating conditions.

Why haven't my plants been growing since I changed the tubes?

Depending on the tubes used previously, installing new tubes can result in a changed spectrum of light. The plants then have to adapt to the new spectrum with their light-harvesting pigments (this does not just refer to chlorophyll, but instead, to so-called accessory pigments as well). This process may take anywhere from a few days to around two weeks. Accordingly, when tubes with a different spectrum are installed, most plants react with a short-term stagnation in growth.

After I installed new tubes, algae started growing in my tank.

If algae start growing after tube replacement (especially if all of the tubes were replaced at the same time), there are two potential causes:

1) An increase in light due to the new tubes:
Although plants can react to increased amounts of light quickly, plant fertilization must also be adjusted accordingly. A lot of light means stronger plant growth, which in turn results in an increase in the plants' nutrient requirements in terms of CO₂ and trace elements. This applies all the more when reflectors are used additionally above the tubes.

2) Changes in the light spectrum:
Depending on the tubes used previously, installing new tubes can result in a changed spectrum of light. The plants then have to adapt to the new spectrum with their light-harvesting pigments (this does not just refer to chlorophyll, but instead, to so-called accessory pigments as well). This process may take anywhere from a few days to around two weeks. Accordingly, when tubes with a different spectrum are installed, most plants react with a short-term stagnation in growth.

Therefore, it is often advisable not to replace the tubes all at once and instead, to replace one tube at a time at two-week intervals.
