Both Lamps at Once.
.
Unless someone in the 'team' has a fetish for cardboard boxes, the far setup (showing old lamp + PSU) looks VERY much like the setting for the new demo lamp...
In photo of new lamp, in its demo setting, attached here:-
The laptop is on a high wooden table/desk
The front cam is on small tripod on 1 box
in front of demo lamp is pile of 3 boxes
the wall is near right-hand of demo table, as and when seen from front cam
....this would be the wall that we see illuminated in the EM/GEIGER test reflection (shown by h_l earlier)
the pile of boxes is probably being used there now to support the SKLed + red tube
the old PSU will be providing power to the SKLed, with the red digital displays adding to the red reflections (as guessed earlier by h_l)
