daytime matrix T5/T8 adapter set for installing the daytime matrix in an existing T5/T8 luminaire. This adapter set is used to convert an aquarium with conventional light bars or covers for fluorescent tubes with a diameter of 16 mm (T5 standard) or 26 mm (T8 standard). The width of the fastening elements can be adjusted and adapted to the frame spacing. The matrix LED lights can be quickly and easily inserted into the existing tube holders (sockets). The matrix is not supplied with electricity via the sockets. The distance between the center of the tube holder and the lower edge of the matrix is 45 mm. The aluminum alloy used - typical for daytime - corresponds to the seawater resistance according to DIN 81249-1.These adapters do not work with JUWELaquariums, as the distance between the tube holders and the water surface is too small.our adapter profiles are the optimal solution for JUWELaquariums .
