The Lighting
“Lamps
are suspended from silk cords with iced shades which hang from the dome.
Lamps in brackets are also arranged around the walls. Over the main
entrance is
a bracket carrying a large globe with lights in the interior.”
(Opening night record)
It
was a remarkable feature of the new building because “electric lighting
was quite new in New Zealand theatres”. Stage lights included 3 borders
each containing 18 lamps and 30 footlights. On each side of the stage were
movable ground lights, each carrying 10 lamps. Below the switchboard was a
dimmer with connections at five different points under the stage floor for
the production of scenic effects.
However,
“the Wanganui Opera House was lit from the outset by electricity rather
than gas. An erratic supply caused early problems and for the opening
season power was generated in the theatre.
 |
Later in the season, this
supply had to be supplemented by the Council’s traction engine and later
still by a 16 HP engine (pictured). As the noise from this often drowned out the
performers, the Council had, reluctantly to fall back on gas until
electricity was laid on from the town’s tramway system.” |
The
plant was located in the basement at the rear of the stage and was a
Crossley special electric lighting gas engine. It was guaranteed by the
makers to give 19.2 HP with a constant BHP of 16.5 running at a speed of
250 revolutions. The dynamo was Crompton made, with an extra fly-wheel and
an outer bearing capable of lighting 166 16 c.p. lamps. The main
switchboard carried a voltmeter main, controlling the switches and fuses
on a slate base. Two large distributing boards on stage were used for
controlling lights on stage and in the auditorium.
Resident recalls machine in
action
“I
had the opportunity to see and hear this machine in action in the late
thirties and it has left a lasting impression.” Eldon Burkitt, Wanganui,
movie projectionist and historian. (March, 1999) Here he describes his
impression.
“Hidden
away in the gloomy confines under the stage there existed an unusual
machine that intrigued those who saw it. It was an electric generator
which supplied power in the very early days. It was not used once
electricity was installed from the city supply. In those days steam
powered generators were quite common. This one, however, did not run on
steam. An internal combustion single cylinder engine which ran on the
town’s gas supply powered this one.” He notes that in WW2 gas
producers were fitted to cars when petrol rationing was imposed on all
vehicles. “The gas mains delivered gas to a large bellows arrangement on
the wall and this in turn was fed to the motor, a kind of reservoir
supply. This was ignited in the cylinder and a large flywheel belt drove
the generator. Probably rated at 110 volts it would have produced quite a
number of volts. The 16 HP Crossley gas engine, with a massive 7ft (2m)
flywheel, was built in 1899, it was, in 1958, thought to be the last one
of its kind in the country still in working order. “
Electricity still meets
needs
Today
electricity continues to meet most of the energy needs of the theatre. On
warm nights the balcony on the first floor is open and floodlighting makes
the front of the building look spectacular. Wanganui-based Midwestern
Powerco gifted $4000 gift of exterior floodlighting for the Victorian
theatre in 1992. The
gift was a gesture made to mark the company’s 70th year. Powerco board
chairman Peter Warnock said the directors believed the opera house was a
worthy recipient of the presentation because it was used by people from
throughout the region. The old floodlights cast a lot of shadows and
needed replacing. Powerco improved under-verandah lights at the same time.
The engineer who designed the system, Neil Griffin of Corys Trades and
Electrical Supplies, of Wellington won a national exterior lighting award
in the 1993 Institute of Illuminating Engineering National Lighting
Awards. Mr Griffin’s design was awarded one of two premier awards, from
36 entries and 8 finalists. The Opera House holds the award. (WC5/10/1993)
