Oh, that's not a simple question I don't know, if you understand russian? But I'll try to explane and give some examples. Allmost all types and names of RKU-01 (and 02) you can find in this table: http://www.miestai.net/forumas/showpost ... tcount=440 In russian RKU (rus. РКУ) are versions for mercury (pol. LRF) lamps and ZKU (pol. RZKU) (rus. ЖКУ) means lanterns for sodium lamps. But I don't know which number exactly belongs to each version of RKU-01 RKU-01 were produced in three russian factories - in Lichoslavl "Svetotechnika", Taldy-Kurganski experimental factory and "Gorelektroset" factory in Penza. Some examples you can see here:
1) Small version for 125 W mercury lamps (RKU-01-125-05) http://www.miestai.net/forumas/showpost ... tcount=352
2) Big version with opening iron case (with three locks) http://www.miestai.net/forumas/showpost ... tcount=162 http://www.miestai.net/forumas/showpost ... tcount=164 http://www.miestai.net/forumas/showpost ... tcount=347
3) Big version with not opening aliuminium case (withuot locks, it opens only thruogh reflector) http://fotkidepo.ru/?id=photo:596570 http://www.miestai.net/forumas/showpost ... tcount=158
4) ZKU (ЖКУ)-01-400-001,002 with aliuminium case and smaller reflector for sodium lamps: http://fotkidepo.ru/?id=photo:186077 http://vkontakte.ru/photo-1844648_141924792
And 2 versions of RKU- 01 very similar to Narva LBL - "Penziuk" and it's copy by "Svetotechnika" (both similar to Narva LBL) (РКУ-01-250, 400; 007, 011?) (found only in Russia)
1) RKU-01-250-011? made by "Svetotechnika", Lichoslavl. Very similar to "Penziuk": http://fotkidepo.ru/?id=photo:313774
2) РКУ01-250-?? made by "Gorelektroset" in Penza - real "Penziuk" http://fotkidepo.ru/?id=photo:312915 (both versions in compare with Narva LBL: http://fotkidepo.ru/?id=photo:447696)
