From Episode #114, The Case of the Blind Man's Bluff
It appears that the "black ray" ultra violet lamp used forensically in this episode was a Blak-RayŽ B100 Series High Intensity model manufactured by UVP of Upland, California. This model, unlike in the episode, requires an external power source. The coiled-up power cable should have been plugged-in somewhere.
As seen in the episode. Note the unused coiled-up power cable.
The current model B-100AR. Similar, but not the same.
