Hello Roman. So this is technically the successor to the DRL-M 250 lamp with two electrodes ?

Hello Olav! Unfortunately I did not see the early lamp DRL 250 with two-electrode arc tube yet. Therefore You may be right -- or no.

This is a lovely shape, the metal heat shield disc is an interesting feature.
