New museum items

Linestra 220-230V 35W (Osram)

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.

Softone 20W S (Philips)

High quality lamp. It has an outer glass envelope and 3 discharge tubes. The ballast heats up the electrodes, which is the reason why it lasts so long: 20 years. Made in Poland.

HPL-N 125W (Philips)

Another bulb that I got with SON-H 110W bulbs. Although it is almost 20 years old, it did not darken much, because before the general replacement of lighting, there were areas on the street where the lamps were not turned on often, and this is how these bulbs survived.

ДС 235-245-60 (МСЭЛЗ)

Less common and unique light bulbs. In the picture, both bulbs are the same. One of them does not work, although it has an unbroken coil, there is no damage to the filament. The power is 60 W, and the operating voltage is 235-245 V.

F 40W/54 (GE)

I got this tube yesterday from electrical shop. Tube isn't used too much and has nice color rendering. It gives 2450 lm of 6500K light. It was replaced with LED tubes.

H 40W/Warm Weiss (Tež Tesla (tt))

The picture shows the tubes I got last year together with Tesla 40W DS tubes. I started arranging the gallery and I decided to place these tubes separately in relation to Tesla because they differ in a brand that is unknown for now because one man told me that they are not NARVA's productions.

Uplate: Tubes are from tt (Tež Tesla).These are export made, but ended up being sold on local market by mistake.
