Local Philips MA 90s (SRS 201s)

The MA 90 appeared here in the mid 1980s - as both the gear-in-head and gear-in-base versions. I would guess that the gear-in-head version was first used in the mid-late 1990s but only in small numbers as the Thorn Alpha 4 has always been the preferred choice.


This MA 90 in Willington (complete with the old-style mounting spigot) is mounted at the unusual height of 6 m.


This example is also in Willington and is also mounted at 6 m! Both this and the previous installation have since been replaced.


This gear-in-base MA 90 in Allestree is on a sleeved 8 m Stanton column. A Royce Thompson P42 two-part cell is employed to switch the lantern on/off.


The column that supports this MA 90 on Broadway in Duffield appears to have been designed to resemble the style of older columns along this road that support Thorn Alpha 9s, owing to the use of a curved bracket.

 

The detector for a Royce Thompson ER4N two-part photocell can be seen emerging from the lantern's canopy.

 
 

This elderly wall-mounted, gear-in-head MA 90 is located in Matlock. A newer MA 90 can be seen in the background.

The MA 90s seen above are pictured again below; this time, on a wintry Friday, 3rd December 2010.

A close-up of the farthest MA 90 in the above picture:


This gear-in-head example was not in use for a while - originally, the column was installed beneath the tree but was moved when the lantern and bracket were fitted a few years later.

Nearby is an MA 90 that has been converted to part-night operation.

 

A Zodion SS9-DLS photocell can be seen fitted in the lantern's NEMA socket.

 
 

The late November / early December 2010 snowfall again provided excellent photographing opportunities. Despite the following MA 90s all being operational the night before (and thus, become warm), the temperature was so low that previously melted snow on the canopies had re-formed as icicles.
