Lantern acquired in December 2007.
This lantern was also used at the stately home as the Kingswood Precinct (and was also supplied by Kingswood) but was used to light a backyard service entrance. It was removed when this area of the house was extended and built on.
This example has, clearly, seen more use than my 70 W example has. Unlike that version, this lantern was installed side-entry.
This lantern is also not fitted with a photocell. The AEC logo is different as well.
At least, this lantern features the familiar red thumbscrew to hold the canopy in place.
As with the Precinct, a Tridonic ballast and Parmar ignitor are fitted.
The reflector is the same, inside and out, as the one in the other example is.
Restoration of the lantern commenced on Friday, 29th June 2018. The lantern was stripped down to its component parts; all of which were treated to a much-needed clean. Painting of the canopy exterior followed.
The reflector was cleaned and polished.
The lantern chassis was washed but left unpainted.
With the gear tray removed, the inside of the chassis allowed the original light grey colouring to be seen.
An adaptor fitted within the lantern's spigot entry allows 34 mm diameter brackets to be used. Two spacers (resembling 5 mm grub screws) ensure that the bracket is mounted centrally within the adaptor, while a single 'real' 5 mm grub screw secures the lantern to the bracket.
The gear components and wiring were wiped down on the gear tray, but were not removed. Incidentally, the capacitor was manufactured in 1995.
The (previously) rather grubby bowl was given a much more substantial wash, however.
The lantern was reassembled; fortunately, everything still fitted together as comfortably as it had previously.
The bowl can be installed either way around in the lantern - the refractors are symmetrical.
The difference in diameter between the 60 mm intended brackets and the 34 mm adaptor is evident here.
The lantern was attached to a wall bracket on Friday, 6th July 2018.
The lamp's warm-up was relatively slow, suggesting that it had been run for considerable hours prior to entering the Collection.

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|
This showed that the lantern's capacitor was defective, although, as the power consumption was still low, I will probably not change it for the time being.
