Sylvania Grolux Tubes

Grolux fluorescent tubes provide the most optimal light output for plants and aquaria.

For Plant Growth

By producing high levels of blue and red radiation, Grolux tubes promote photosynthesis in plants making them ideal for the artificial lighting of plants in indoor gardens, florists or greenhouses where there is insufficient daylight.

For Aquariums

In addition they’re also known to promote fish activity and help enhance the visual appearance of the plants and fish in fresh water aquariums.

Grolux tubes are available in both T8 (26mm diameter) and T5 (16mm diameter) ranges of varying lengths. The T5 Grolux tubes have a higher output per watt in comparison to the T8 versions.
