Glostertube was founded in Milano in 1953. Our principal goal has always been the Customer satisfaction achieved through a continuos quality care of our products and a fast and accurate service.
Our main products are the fluorescent coated glass tubes.
Raw materials are best quality glass tubes and phosphors.
The glass can be lead, lead free , borosilicate, coloured and soda.
The phosphors are made with inert matter where impurities are dispersed. These impurities are able to absorb energy from the electric discharge and to return this energy as light of a given wave length and therefore of a given colour.

Glostertube coats glass tubes in dimensions ranging from 6 mm to 38 mm diameter and from 1500mm to 3200mm length.
The phosphors, give to the tube when lighted several colours ranging from white tones, warm almost pinkish to cool as ice, to pink, blue, purple, orchid, salmon, cyclamen, green, yellow, ect.

We also have in our range some whites triphospor with high lumen efficiency and CRI, very suitable for architectural lighting.
