D.W. Windsor Iffley

Lantern acquired in July 2011.

This lantern had been privately owned and was installed in a garden. It then entered the Collection when the resident moved house, as they no longer had a use for it at their new address. Several Iffley lanterns are installed in the South Derbyshire village of Repton; all were installed on existing cast iron columns following a refurbishment in 2003. Unsurprisingly, these lanterns also see use in the village of Iffley, in Oxfordshire.


Unlike the Iffleys installed in Repton, this example does not feature a straight-sided deep bowl; instead, a more bulbous and shallower bowl is employed.


An unusual top-entry connector is fitted in this lantern's canopy. Below this can be seen a Royce Thompson Microstar 2000 miniature photocell.


The lantern incorporates the familiar 'Diamond Optic' reflector. A common mistake when installing these lanterns is that they are positioned 'backwards', in respect of the carriageway's position. The correct optical setting is for the lampholder to be positioned at the front of the lantern.


Two clips secure the bowl, which, when released, allow the bowl to hinge down for maintenance. The bowl can be removed entirely, if required.

The lamp control gear is all fitted to a removable central section of the lantern. When in use, the gear was wired out as a Philips SL compact fluorescent lamp was instead fitted. Instructions on how to change the lamp are included, even though there is no reason as to why this method would be used, as the reflector is open.


The various numbers on the lower part of the central section relate to different angles - the reflector can be adjusted in order for the lantern to produce different beam distributions, as required. Interestingly, despite the lantern being designed for running a 50 W SON lamp, the ignitor is more suited to starting SON lamps with a minimum wattage of 100 W, though it can also operate metal halide lamps with a minimum wattage of 35 W - SON lamps requiring a lower starting voltage in comparison to their metal halide counterparts.


The lantern's main connector block is located within the inside of the canopy. Nearby, the other side of the photocell is visible.
