An ordinary tube for Serbia. Although few people have heard of 30W lamps, in Serbia, FEP produces fittings for them, as well as ballasts. The color is even and gives a lot of light. An interesting piece for the collection.

A very interesting tube, although not old. It is interesting because they were rarely sold, because 6500K tubes were (and still are) more popular. This brand is also rarely found, because the most common one is Phillips.

On the picture you can see light bulbs that were rarely used in Serbia. The reason is the use of traditional fluorescent lamps and tungsten light sources in lighting. Most of these lamps were imported for newly built objects, but their time is running out because LEDs have replaced them.

The 9kW lamp is only slightly larger. About three years ago OSRAM also began to build a lamp size between 6 kW and 12 kW.
