New museum items



FC BB 18W, FC DS 18W (Tesla Pančevo)

Here are the T8 tubes from Tesla. These tubes are both burned out Sad DS one lost vacuum due to short circuit, BB one was used and got cathode broken. Color of DS on this one is about 5000K (factory used different coating for short period), BB color is similar to 33/640. Tubes have cathode guards, which was only seen on T8 tubes. Coating is as smooth as Philips ones.



FC DS 20W (Tesla Pančevo)

Here are the first tubes in collection. I bought 5 of them in 2017 and only 4 survived to this day. 3 of them are 100% working, 4th one has broken wires. Color is daylight (DS), CRI is good. Tubes are new and have less than 10 hours of use.



ЛБ 40-4 (SLZ)

Another rare lamp, already well-worn, but quite durable, the same LB color from childhood, although it greens the camera, the very caps that were the "hallmark of daytime lamps" when I was just a jerk looking for them everywhere and everywhere.

The etching at the end is practically lost, but it can be seen at some angle.

I preheated mercury stains about an hour before shooting and another hour after, they practically stretched out.



1УБЕ-40/220-ВП-05У4 (Луйс)

Retrieved from an unidentified fixture. It worked there in tandem with 1UBI choke. I have no clue on what is the difference with the 051 series. The quality is disgusting. Ignites the lamp from the 3-4 attempt and hums like a tractor. Together with its "partner" they were set aside and replaced with electronic ballasts.



1УБИ-40/220-ВО-051У4 (Луйс)

Retrieved from an unidentified fixture. It worked there in tandem with 1UBE choke. Despite the manufacturer, a fairly high quality sample. No noise and reasonable heating during operation. Possibly this is due to the year of manufacturing (1975).



QTi 2x14/24/21/39 (Osram)

Quite by accident I came across an advertisement for the sale of electronic ballasts for $7.5. Therefore, without thinking for a long time, I bought 4 such ballasts for replacement in garage fixtures. Since the buzzing of regular chokes was just starting to drive me crazy.

As you can see from the photo, they are capable of working with different types and wattage of lamps. The ignition is always stable. There is no flicker.



220V 100W (Tesla)

During cleaning in the pantry, I found this exhibit. Honestly, I can't even think of where did it come from.



НСБ-? (Электрометалл)

An elegant chandelier from the late fifties of the last century. The markings that we managed to find are on the lampholder mount. It contains the following information: "Electrometall, Tallinn, 220 V / 75 W, GOST 8607-57, 1959". The lamps, together with the lampholders, are placed horizontally in the cavity of the glasses, illuminating the room with a pleasant soft light, diffused by frosted glass cups and reflected from the ceiling. In order to remove the cover, it is necessary to unscrew the bulb and partially disassemble the lampholder.



НСБ-?

Luxurious chandelier made in the Stalinist Empire style. Manufacturing materials: brass, bronze, steel, bakelite, glass (glass or crystal - I can't judge). Since there is doubt, let it be glass. This, in my opinion, does not detract from the artistic value and historical value of this product. Unfortunately, no markings could be found. Internet searches have yielded no positive results. For the manufacturing date of the chandelier I took the year of production of one of the lampholders, which I had to repair after the purchase.



«Камелёк» (МЭЛЗ)

"Kamelyok" souvenir night light from the era of the distant seventies was designed to create an atmosphere of peace and home comfort. The body is assembled from the identical brass elements, connected by plastic corners using screws and nuts. The glow discharge lamp (with E27 base) flickers pleasantly when glowing, imitating the quivering tongues of flame. At that time, this lamp was very expensive. I bought it in those distant years as a gift to my grandmother on her birthday.
