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 T5 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 animals and plants. It supports their growth and their photosynthetic performance. Perfect plant growth 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”.

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.

Which electronic ballasts should be used for JBL Solar ultra T5 ?

The technology for fluorescent bulbs is standardised so that the manufacturers of the lamps and the ballasts both determine the ignition and controller of the tubes.

For this reason the tubes can be operated with any electronic ballast.

Can the JBL Solar ultra T5 fluorescent bulbs be operated with conventional ballasts?

No, this is not possible.

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.

PUSH messages from JBL

What are PUSH messages? As part of the W3C standard, web notifications define an API for end-user notifications that are sent to the user's desktop and/or mobile devices via the browser. Notifications appear on the end devices as they are familiar to the end user from apps installed on the device (e.g. emails). Notifications appear on the end user’s device, just like an app (e.g. for emails) installed on the device.

These notifications enable a website operator to contact its users whenever they have a browser open - it doesn’t matter whether the user is currently visiting the website or not.

To be able to send web push notifications, all you need is a website with a web push code installed. This allows brands without apps to take advantage of many of the benefits of push notifications (personalised real-time communications at just the right moment).

Web notifications are part of the W3C standard and define an API for end user notifications. A notification makes it possible to inform the user about an event, such as a new blog post, outside the context of a website.
