When a leaf or flower is dying you can cut these off, see plant care how to do so.
The technology integrated in the Living Light lamp does not affect the plant or its (natural) surrounding. So, you do not need to worry that the ecosystem is being harmed by the technology. If, for whatever reason, the plant dies, you can replace it by yourself with one of the specified Living Light plants, which you can order by sending an email to [email protected]. See how to replace your plant how to do so.
After the new plant is adapted to its new environment, the energy system will recover itself and the Living Light lamp will be up and running again. You can also place your own plant in the Living Light, however we cannot be accounted for the risks of lack of functioning of the Living Light lamp when you decide to do so.
