ДРИ 175 (СЭЛЗ)

The 175W metal halide lamp. Color (color temperature) at a rated current is just over 4000K. Nice sample for the collection.

NAV-E 400W (Osram)

The 400W sodium lamp in an ellipsoidal frosted bulb. Thanks to the matte finish, the light does not hit the eyes that hard. The color rendering has not been improved in any way, and therefore it is better to use this lamp only in industrial facilities.

LRJ 400W (Polamp)

The 400W ellipsoidal metal halide lamp. At rated current, the light is very similar to an incandescent halogen lamp, but when operating from a standard choke, this lamp cannot enter the normal mode.

ДРОТ 2000 (Разряд)

Metal halide lamp for irradiation of plants. Notable for the shape of the flask. To power this lamp, you need a 380V supply and an appropriate ballast. I managed to run it at 1/3 of the power from LATR regulated transformer through a choke for DRL 1000 and IZU. To start, I also had to additionally touch a lamp with a plasma ball. It is not very correct to judge the color of the glow in this mode, but it is very pleasing to the eye and is well reproduced in the photo No. 3.

HL2-3,8-400 (Telpod)

Series compensating capacitor manufactured by Telpod. These were put in 2 pieces in parallel, working with the 1UBE80 ballasts.

1УБИ-80/220-ВП-312-У4, 1УБЕ-80/220-ВП-312-У4 (ЦП ВОС)

Cumbersome chokes for creating an anti-stroboscopic (with highly reduced luminous flux ripple) luminaire for two 80W fluorescent tubes. The capacitive branch works through two paralleled Polish capacitors Telpod HL-2-3.8-400 3.8µF +/- 5%, designed for 400V AC voltage with a frequency of 50Hz.

Production of the CP VOS (I do not know the specific plant).

ESRR 46/20

Foreign neon lamp in the form factor of a switchboard lamp. In Europe, such neon indicators were very common, but I do not know if they existed in the USSR. At the end of the bulb there is a focusing lens, it shines with a distinct blue tint.

230V 100W (Mazda)

Interesting incandescent lamp. The cylindrical bulb, the dense arrangement of the filament and the darkened upper part betray its, probably, searchlight purpose. On the side there is an inscription MAZDA 230v 100 (?) W gasfilled lamp 70. The stengel and one of the terminals inside the base are covered with an insulating tube.

ИН-?

Miniature foreign neon lamp with E10 base. The electrodes are 2 dark metal plates. It shines very nicely.

«Домик» (КЗРП)

Christmas tree lights switch. It has a circuit with an electromagnetic relay. The body is metal, made in the form of a hut. You can connect two garlands to it, which will be switched on alternately - there are two sockets on the rear panel for this - "GIR-1" and "GIR-2". Also on the rear panel there is a handle of SP-1 regulator. In the window on the front panel, there is a neon lamp (unfortunately, I do not know its type), which lights up and goes out simultaneously with a garland connected to the "GIR 1" socket.
