Cyrillic etch, Wow!

I am presuming that they are made in 4th quarter of 1989?

Pretty, please no more Chinese failure.

These seem to be pretty good colour quality mercury lamps, normally you only see ДРЛ125(6) lamps but yours are ДРЛ125(15). I am fairly sure the last number refers to the % of red radiation, and 15% red is rather good for a mercury fluorescent lamp.

Yes, is Red. 6 - is the smallest number. It was 6, 8, 10, 15. These phosphors were invented at different times and applied to certain lamps. 15 was only on 50, 80 125 watt. It was also written that was project phosphors 12 and 14 were invented. For a long time it seemed that they were only on paper. But unexpectedly, i found a phosphor 12 in last year.

Other numbers after the parentheses are indices of the difference of the model.
