Holophane Wallpackette 2
This bulkhead is unused; however, the Wallpackette fittings are very common as security lights and even for general street lighting where particularly narrow roads mean that regular lanterns cannot be installed. Surprisingly, I have seen more mercury examples than SON ones - maybe Holophane had trouble fitting ignitors to these in the past, and elected against using internal-ignitor lamps.
This Wallpackette dates from 1992 but is unused - it had been left in a storeroom for its entire life; hence the surface dust on the front. The anti-vandal lens guard is an optional extra though the lens itself is constructed out of thick glass, so it would still be hard to break without the guard.
The back of the fitting has a number stamped onto it but there aren't any other details.
The front part of the Wallpackette is held in place by two clips.
With the clips unfastened, the front hinges open through 90 degrees and the lamp and gear are revealed. There are cable entry holes on either side of the gear area and these are plugged with conduit stop pieces to ensure that dirt or moisture cannot enter the bulkhead. The ballast was manufactured in April 1992, with the capacitor being made between the 13th - 19th.
This view clearly shows the refractor patterning. Two fixing screws and collets were included with the Wallpackette.
Once the surface dust had been removed from the bulkhead, I wired it up and then switched on.

Testing with my energy monitoring device revealed the following results:
Test Voltage (V) | Current being drawn at full power (A) | Measured wattage (W) | Apparent Power (VA) | Frequency (Hz) | Power Factor | True Power (W) | Difference to rated wattage | Percentage Difference |
246.2 | 0.49 | 92 | 121 | 50 | 0.73 | 88.07 | 18.07 | 25.81% |
