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.

Now about the very sad thing - one electrode didn’t seem to survive the transportation , although I didn’t drop it, didn’t put it on the floor during the transport, and didn’t knock it. I'll try to weld electrode with 12 volts, but it is bent to the center of the lamp and to the side, there is no contact of a thin spiral with a piece that remains in the electrode, you will have to knock hard, it may completely fall off.

Therefore, before the operation, I immortalize it in the museum in working form, it works with a closed electrode, VS starts up in almost normal mode, with one electrode warming up, T12 means T12.

Many thanks for the lamp to Gospodin Horoshy.
