Studio Due – City Colour 2500
Studio Due – City colour 2500
The city centre light is similar to the wash light as it projects one block
of colour, the colour gets brighter as the lamp heats up. The light gets
very hot however the heat is distributed so it is not one part of the
light getting hot and doing damage to the light. This light is also water
proof so it can be used in any weather conditions. The powerful light
beam can create numberless colour shades. The studio due city centre
was selected to illuminate the major section of the mast in Australia. I
found one if these lights for 1,900 euros for second hand on
sourceEurope.com. You would use them outside or in a large venue
because they produce a large amount of lights and are very bright and
have a large spread.
The difference between the city colour and nova flower are, the city
colour stays still and does not move, the nova flower moves in various
positions so the nova flower would be better for more exciting
lighting.
Scenario:
I would use this light outside as it is IP rated, I would use it to light up
buildings such as a castle, it is very bright due to its 2500 watt lamp
and has a wide beam angle of 50°x52° meaning less fixtures could be
used.
Comparison:
I would use this over a nova flower light because the nova flower does
not wash a wall/room, it creates a pattern.

Nova Flower Light
The nova flower is a 1200 watt lamp which is waterproof so it can be
used in any weather conditions. The light beam projects onto a metal
plate and goes up into the sky making a moon flower shape in a vary
of colours. The nova flower is weighed about 88kg which means It is
too heavy to transport easily so it is placed on a flight case so you can
easily wheel it around. The nova flower has 14 channels: 1) colours, all
the combinations, 2) colours motors speed, 3) reflectors speed, 4)
lamp on/off + reset, 5) shutter, 6) magenta, 7) cyan, 8) yellow, 9) pan 8
beats, 10) tilt 8 beats, 11) pan 16 beats, 12) tilt 16 beats, 13) pan
speed, 14) tilt speed. This light has been used at big venues and had a
huge impact including the Paul O'Grady show and the x-factor and the
mtv awards. I found a nova light second hand for £3,500, however you
could double the price if it was brand new.
Comparison:
The difference between the nova flower and a moving head are the
following: a moving head is a lot smaller and doesn’t produce as much
light, the nova flower is a lot brighter and bigger.
Scenario:
I would use this light outside as it is waterproof or indoors at a concert
or extremely large theatre as they give out a lot of light due to the
1200 watt lamp.
Moving Head
The ultra-compact MAC 101 LED moving head wash is available in three white light versions that expand its use to
applications where high quality, pure white light is needed. The MAC 101 CT incorporates both cold and warm
LEDs instead of RGB for a better white light quality and greater output. Colour temperature calibrated to ensure
visual consistency across fixtures, the MAC 101 CT allows for easy changes in colour temperature from crisp cold
looks to warm shades, and features simple intensity control.
• High quality LED white light
• Ideal for highlighting skin tones, textiles or set pieces
• Variable colour temperature
• Tight and punchy beam effects, long throw
• Multiple field angle options for a perfect wash
• Incredibly fast and precise movement
• Less than 125 watt total power requirement
Scenario:
I would use this light to wash the stage with a block colour as it isn’t very big and is easy to place. I would use this
light in a concert to create effects for the performance.
Comparison:
The difference between a moving head and a Fresnel light are the following: a moving light can be various
difference colours and can move at many angles. The Fresnel is set as white or clear and lights up one area
as it stays still.
Fresnel
The Fresnel light uses a circular reflector. The lens is not very precise however it gives a very soft edged beam as well as
spreading a great deal of light outside the beam (spill). The light can be focused in order to alter the size of the light beam
but it cannot project gobo images. Even though the Fresnel light isn't very efficient, it is a good light for stage lighting.

Extremely Versatile Light
Scenario:
I would use this light to wash a stage for a theatrical production as it is a flood of light and you can put coloured gel in
front of it to create a coloured light.
Comparison:
The Fresnel is the opposite to a pin spot because the Fresnel lights up a big area and the pin spot only lights up a
small area.
LED Pin Spot 2
The LED Pin spot 2 includes two front focal lens options to produce hard-edge beams for a variety of applications. The
LED Pin spot 2 is extremely lightweight and is powered by a 3W white LED. The auto switching power supply allows the
fixture to adapt to the voltage provided, ranging from 100V to 240V.
• Light Source: 1 (white) 3W (700mA) LED 50,000hrs
• Beam Angle: 6° (installed), 9° (included)
• Illuminance (6°): 4,120 lux @ 2m
• Illuminance (9°): 1,335 lux @ 2m
• Input Voltage: Auto-ranging 100 - 240VAC 50/60Hz
• Power and Current: 4W, 0.1A @ 230V 50Hz
• Weight: 0.4kg
• Size: 193 x 105 x 148mm
• Approvals: CE
Comparison:
The pin spot is very different to a Fresnel light because it is a
very narrow spot light and you could not light up a stage
with a pin spot, only a small area of the stage or a person.
Scenario:
I would use this light to light up a musician during a gig.

I have compared the Chauvet lighting desk to the showtec lighting desk, here are the
differences:
• The chauvet lighting desk is lighter than the Showtec
• The showtec lighting desk holds more channels than the Chauvet lighting desk
• The chauvet lighting desk had anologue controls
