Siemens SRL35

Lantern acquired in November 2004.

A nice change now, as this lantern is brand new and was even still boxed when I received it. It was stored in the same 'magic' storeroom that the Alpha 6s were in, although quite why it was never used is a mystery as it doesn't use anything that is hard to come by today. SRL 35s are not a particularly common lantern in the Derby area, as lanterns such as the Thorn Beta 5 and Philips MI 26/XGS 103 have always been preferred; however examples do exist on some roads built or relit in the mid-1990s.

This lantern is about the smallest 35 W lantern available - even smaller than the Beta 5, and so the box was also very small. In fact, the word I'd use to describe it is "cute"! Don't worry, I'm receiving treatment for these odd descriptions! (The reason that it is soaked in the picture is because it was left outside when the storeroom was cleared out.)

A close up of the sticker. It is interesting that the original name for the lantern is mentioned as well. The NEMA socket on this lantern is dated March 1995, so it is possible that both names were used to avoid confusion if lighting managers were still using GEC codes and catalogues; the company only having closed a few years previously.

The tape holding the box closed had long since lost its stickiness, so it was easy to open the box without tearing the cardboard. Once I'd opened it, I instantly saw the lantern - there was no packaging to protect it.

Looking down on the lantern, the canopy is very shiny indeed. If a photocell were to be fitted, the small cap covering the terminals of the NEMA socket would be removed, but I won't be doing this as the lantern doesn't need photocell control.

From the side, the size of the lantern becomes fairly apparent. Although the canopy is thicker than the Beta 5's, the bowl is does not have as much depth as even the Beta 5's shallow bowl.

Another difference between this and the shallow bowled Beta 5 is that the bowl has refractor lines beneath the lamp area, whereas this area is clear on a Beta 5.

The gear for the lantern is reached by undoing two screws and then sliding the gear tray past them. Once removed, it is held by two plastic ties, which probably would become brittle if the lantern were to be used on a nightly basis.

The lantern is so small that I managed to perch it on the end of a shelf. When I powered it up for the first time, the lamp stayed red for quite a while, but on the second occasion, it warmed up much faster.

With the flash on, the lantern actually looks like part of the shelving!


The lantern was mounted to an AC Ford AC872 wall bracket on Sunday, 21st August 2005.
