Yes, it's an amazing scene and David Warner and Ronny Cox deserve their fair share of credit for those episodes.
I recently made a tweet about the harsh lights in a maternity unit waiting room I was in reminding me of the torture chamber in Chain of Command. I obviously ended the tweet with "There are four lights!!".
Within one minute of having sent the tweet, I got a tweet back from someone called @Gul_Madred who simply said "No... there are five".
