Philips MA60 180-watt SOX lantern. Primarily for main road and motorway
use the Philips MA60 was the largest member of the MA range of lanterns
produced by Philips; MA meaning Main road lanterns. Like all lanterns in
the MA family, the MA60 has a fibreglass canopy and injection-moulded prismatic
bowl. Although still available from Philips, the MA range has been
re-designated as the SRS 201 range of lanterns by Philips, but remains more or
less unchanged in design.
There are two main variants
of the MA60:
- MA60-OO: Remote-geared version, where the
control-gear is mounted in the base of the column.
- MA60-GO: Geared version, where the
control-gear is mounted at the rear of the lantern in a separate housing
known as the 'shoe'.
Both versions of the MA60
are represented in the collection.
The MA60-OO remote-geared
version came from Walsall in the West Midlands in 2004, and was a victim of
Walsall Metropolitan Borough Council's PFI scheme. The lantern is thought to
have come from the Streetly District of Walsall and was the best example found
at the time of my visit to the Contractor's yard. Unfortunately its canopy is
quite tatty in appearance and the lantern will be replaced if a better example
is found.
There are in fact two
'geared' MA60-GO's in the collection. The first is an unused example that came
from the City of Derby (my thanks to fellow collector Jeremy Strichley for
saving this superb lantern for me). The second example came off the A38 at
Fradley, Staffordshire, during November 2005, and was one of the hundreds of
MA60’s taken down on the section of the A38 running from Fradley in
Staffordshire through to Burnaston in Derbyshire. This SON for SOX lighting
renewal programme was part of a huge road improvement scheme that commenced in
2005, and was completed in 2006.
Remote-geared MA60-00's on twin-arm brackets in use on the
A38 in Derbyshire in early 2004. The picture shows what is now the last
remaining SOX lit section of the A38 between Fradley in Staffordshire and
Burnaston in Derbyshire.
The unused example from Derby is the intended
main MA60 exhibit, but the lantern from the A38 will be kept and eventually
restored because having used the A38 between Lichfield and Derby for a good
many years, I thought it sad when this large SOX lighting installation was
dismantled, so it was nice to save one working example for posterity.
It's worthy of note that just beyond the Burnaston A50 junction on the Derby
side of the A38 the remaining stretch of this large MA60
SOX installation was still extant and working in April 2006, and
appears to have been outside of the Contractor's remit to renew this final
low-pressure sodium lit section.
The MA60-GO is a big lantern; the pliers give an idea of its
size. The
'shoe' is the large aluminium casting at the bottom
of the lantern. This
example is the weather-beaten lantern from
the A38.
Sorry,
no image of the MA60-OO remote-geared lantern in the
collection is currently available
The remote-geared MA60-OO has a cast-aluminium spigot
receptor attached to the back end of the canopy, which fixes straight onto the
lamppost bracket. The geared MA60-GO uses the same GRP canopy, but has a larger
aluminium spigot fitting attached to it that also incorporates a large
detachable ‘shoe’ containing the control-gear. The canopy and lens of the MA60
are also used for the integral-geared MA50-GO (SRS-201 135w) lantern, where the
control-gear is mounted inside of the lantern itself.
Access
to the lamp on all models is made by releasing the seven stainless steel
fasteners around the perimeter of the canopy (three of which also act as
hinges), allowing the bowl to swing down clear of the canopy. Access to the
control-gear is made by releasing the two recessed screws in the bottom section
of the shoe; this allows the lower half of the shoe containing the control-gear
to swing downward on a rear mounted quick-release hinge. The whole control-gear
unit can be unplugged in one go and changed with a replacement unit to facilitate
a quick repair to the lantern (see below).

The
shoe, which is hinged from the back, contains the large
leak-transformer
and capacitor. The disc lock and keys give an idea of
scale.
Redundant MA60s strewn along the central reservation
of the A38 at Branston near Burton on Trent after their removal in December 2005. These
lanterns would eventually be broken up into their
component parts by the Contractors at their
Nottingham depot; the SOX lamps being destroyed and
the lantern remains skipped. The new Urbis ZX3 150w
SON lantern replacements in the background were
mounted onto new columns.
A dumped
Philips MA60-GO awaits its fate in late December 2005.
All
of these discarded lanterns had had their
control-gear trays removed so that workmen could gain access to the spigot
fixing screws to remove the lanterns from their brackets.
The tiny yellow
sticker on the bowl simply reads '2001', and probably means that the lantern
was last
overhauled in 2001 (?). The electric cable was left
attached to some lanterns and was used as a means of
quickly lowering the lantern to the ground after removal.
Thanks
to the kind offices of the Contractor a similar lantern from
this contract has been saved for the collection.
MA60-GOs
on a twin arm bracket on the A38 at Branston. When these
lanterns were erected in the early 1990's, no
account was taken of windage, which along with the combined
weight of the geared MA60's would cause
some of the longer twin-arm brackets to bow under the
considerable weight. However, I don't ever recall seeing
any failed brackets, or any fallen lanterns.
