Philips CRX204 Lantern Installations
The Philips Tunlite was designed for tunnel use, and could come with a range of housings and optics. This page documents the S/CRX204 (single-housing) option. The Tunlite as a series could run a range of lamp-types: 70W-400W SON-T Plus, 26W-180W SOX/SOX-E, 4-pin PLL 36W-55W, or 55W-85W QL. The housings for these lanterns are constructed from AlMgSi alloy, sealed from the outside world with a self-adjusting flat security glass cover, hinged on stainless steel inside the frame. Thank you to Mike Barford for supplying the information on these lanterns.

Some SRX204s are located under Derbion car park, along Morledge.
These are no-longer in use, owing to ASD Highway Diamond Midis now installed on columns. Removing these was probably deemed unnecessary, so disconnection followed.

The SRX204s are attached to the roof via four SRX208 brackets.
Although a hard-spot, this one is missing its flat-glass cover.
