Upgrade Summary
The VL5+™ Series Wash Luminaires feature many improvements over the standard VL5™ Wash
Luminaire and VL5Arc™ luminaire, both to the exterior and interior components. The following is a
complete summary of improvements:
•
Improved color matching from luminaire to luminaire. This improvement was accomplished by
installing newly designed Blue, Amber and Magenta color filters (made using an improved ion-
assist process). The new color filters have less color shift problems. An anti-backlash drive ring
was also installed to improve color match and dimmer accuracy, and increase repeatability of those
functions.
• Increased reliability of the Controller PCB. This improvement was accomplished by adding
ventilation holes to improve air flow.
• Increased reliability of Pan and Tilt functions. This improvement was accomplished by retrofitting
the pan/tilt mechanisms with new clutches and encoders, replacing the pan/tilt cable assemblies
and installing a newly designed pan stop which prevents sticking.
• Increased reliability of power and data transmission. This improvement was accomplished by
replacing the Input Cable Assembly.
• Increased reliability of color and dimmer functions. This improvement was accomplished by
replacing all linear actuator motors and connectors.
• Improved light output. This improvement was accomplished by installing a new reflector.
• Improved yoke covers. This improvement was accomplished by installing new yoke sheet metal
which adds support to the yoke covers which will prevent damage to them during normal use.
Ventilation holes have been added to the yoke leg for PCB cooling and air flow, along with heavy
duty yoke covers and new safety tethers to prevent covers from falling off.
• Reduced head temperature. This improvement was accomplished by moving the UV glass to the
rear of the luminaire head, while also switching to a thicker, more durable UV glass. This will
allow replacement of the glass without the need to disassemble the luminaire, along with reducing
the temperature of the Blue/Amber bulkhead, extending the life of filter pads and linear actuators.
• Increased reliability of motor harness. This improvement was accomplished by designing a new
harness with highly stranded 24AWG PVC wire which makes a more reliable connection in the
MTA connectors.
• ( only ) Increased reliability of the lamp strike. This improvement was accomplished by
installing a new solid state ignitor which reduces hot restrike time from 8 minutes (VL5Arc) to 1
minute ().
• ( only ) Added lamp douse switch to yoke cross-member. The switch should be used to
douse the arc lamp before disconnecting the pigtail cable. This will prevent damage to the contacts
in the CPC connector, which can be caused by drawing an arc during disconnect.
