REVO/Relite Hyperion 'B' 140w SLI lantern. This lantern is an example of the second generation of 'Hyperion' lanterns produced by REVO / Relite. Although similar in appearance to the 'A' type, the 'B' type lantern differs in having a pressed aluminium canopy and a flat-bottomed bowl with an ‘inverted Vee' refractor moulded along the length of the bottom of the bowl to improve light distribution. Due to the thin gauge material used to make the canopy, this version of the Hyperion is also noticeably lighter in weight than the earlier cast aluminium 'A' variant.

The Hyperion 'B' in acquired condition, the keys give an idea of scale.

The example in the collection was originally mounted on a 10-metre column and once looked down on to the A460 Cannock Road at Underhill, Wolverhampton. This lantern was still operating on a 'Sangamo' timeswitch when it was decommissioned in May 2005 as part of an on-going lighting renewal scheme for the area, and was replaced by a modern Industria Arc-2 high pressure sodium lantern. It is thought that this particular lantern was originally made for use with 140w SLI/H linear lamps, but was later converted to run single ended 135w/150w SOX lamps.

The flat bottomed bowl with moulded 'Vee' reflector is one of the major differences from the Hyperion 'A'. Note the stainless steel bowl release clip and the two locating lugs, and also the thin pressed-aluminium canopy

Access to the lantern is made by releasing a stainless steel clip situated at the rear of the lantern, which allows the bowl to swing downwards on its front mounted hinge; this is the opposite way around to the Hyperion 'A', which has its bowl-release clip at the front of the lantern, and hinges from the rear.

The lantern seen open and the SLI G-type lamp holder mounting plate for SLI?H lamps can be seen at the front of the lantern. The 135-watt SOX lamp hangs from the lampholder because no lamp support hoop appears to have been fitted to this lantern, so this could be another clue that the lantern was once converted from SLI to SOX?
