Here is my 2nd Soviet 40W lamp. I got it for free with 6 Elektroimpex tubes. I drove it with these 6 tubes on my bike and they survived the ride. The markings on the flask are worn out and barely noticeable. Nice tube.
Here are lamps from Bulgaria. I found them discarded in working condition due to replacement with LEDs. These tubes do not have a date code. The coating is almost uniform like Philips. Pins are made of brass. 6500K color.
This is one of my favorite tubes. It's very durable and you can see that it worked a lot, but here's the miracle: it still turns on fine, gives a lot of light, and colors are clearly visible.
One of the highest quality tubes. I got it new because the building has been renovated and had LED lighting installed. The tube shines beautifully and the colors are clearly visible. There are no cathode guards.
This is an interesting starter designed for 40-65W fluorescent lamps. Manufacturer - tt. The starter is filled with neon and heats up quickly, taking a long time to fire, which means it is nearing the end of its life.
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.
Rare and valuable tubes. I found them thrown out last year. I brought them home by bike. They still shine, although there are traces of long-term burning.
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.
