AEC UNO
Lantern acquired in February 2006.
Another lantern to be removed from one of Markeaton Park's car parks - and another Italian one at that! This lantern was only installed for a short time, when a new pay-and-display machine came into use, but it was also replaced with a Beta 79 to standardise the lighting.
The lantern is of an all-plastic construction (except for the 76 mm column adaptor, which is steel), meaning that it could get away without requiring an earth; however, the ballast has an earth wire running to it, for continuity purposes.
The canopy is plain except for a purely decorative grille towards the back of the lantern.
The canopy hinges forwards for maintenance purposes. It is held in place with the red screw visible between the spigot cap and the bowl.
An ignitor is not fitted - instead, an internal-ignitor lamp is required. (Oddly, the label on the inside of the canopy states that an external-ignitor lamp should be fitted!)
The reflector simply lifts out if the lamp has to be changed.
The lantern was attached to a post-top stand in October 2018, where it was then connected and powered up.

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 |
| 242.1 | 0.46 | 82 | 111 | 49.9 | 0.76 | 84.64 | 14.64 | 21% |
The photographs below show the Beta 79 that replaced this lantern; a part-night 'Night Star' photocell is employed here.
