The Revo C13723T street light lantern for 140w-SO, 90w-SOX sodium lamps

            The Revo C13723T sodium lantern was a new light-weight street lighting lantern first offered by Revo of Tipton in the late 1950s. Shown is the top-entry version, but it was also offered more popularly as a side-entry type for use with 45w, 60w, 85w or 140w sodium lamps. At the time, 85w and 140w versions would be for main road use.

These new light-weight lanterns featuring a one-piece Perspex bowl, replaced a similar looking lantern that had a more intricate 5-panel bowl. The older 5-panel bowl was set in an aluminium frame, three of those panels being made of specially formed figural glass. The other two panels being made of moulded Perspex with a refractive linear pattern to aid light distribution control. A heavier and more expensive lantern to produce, it's no wonder that Revo opted for this simpler version which they described as: - 

'This street lighting fitting comprises of a cast aluminium alloy canopy with internal high quality vitreous enamelled reflector. The lower portion of the lantern consists of a single-piece Perspex bowl with two internal Perspex refractor plates securely sealed to provide complete protection for the prisms. 

The Perspex bowl is hinged to the canopy and may be instantly opened by released two stainless steel toggle action fasteners.

High efficiency and effective light control is thus obtained while the exterior surface is completely smooth to facilitate maintenance.

Apart from the area covered by the refractor plates the internal surface of the bowl is of figured formation.

The lantern is completely weatherproof and will not permit the ingress of dust or insects.'  End of quote.

Often referred to as 'Revo Daleks', because of the array 
of patterned nodules on the Perspex bowls, production of the type had ended by c1967.

The lanterns came in two basic sizes. A smaller lantern for 45w & 60w SO lamps (now 35w SOX), and the larger lanterns for 85w & 140w SO (now 55/90w SOX) lamps. 

Today, very few of these lanterns exist outside of museums and private collections. The last one I knew of in nightly use on a public road, a side-entry type came down in early 2023 after 60+ years of service.
