PowerArc
lights eliminate wasted light, creating brighter
warning lights |
|
| |
As
the size of emergency vehicles has increased, so
has the amount of signal blockage caused by the
design of the apparatus. A common example is the
wasted rear warning signal from a standard lightbar
on a fire engine with a raised cab roof or on the
front of an ambulance. By using controlled arc
elements instead of old fashioned rotators, PowerArc
warning lights put the light only where it is needed. |

|
| |
PowerArc
lights reduce the number of needed warning
devices |
|
| |
One
surface mounted corner PowerArc sweep light
protects two sides of the apparatus, reducing
the need for extra warning devices to comply
with the requirements found in NFPA 1901. Full
lower level protection around the apparatus
is achieved with only four PowerArc’s,
one on each corner of the apparatus. Other
systems require a minimum of eight warning
devices. |
|
|
|
|
|
|
|
| |
PowerArc’s
don’t just comply, they exceed the lighting
requirements |
|
| |
A
PowerArc system exceeds all of the photometric
requirements found in NFPA 1901, ASTM F 2020-00,
SAE J2498 and KKK-A1822-E, and the data is
published. |

PowerArc
oscillating lights create better intersection
protection |
|
| |
Through
oscillation, each PowerArc lower level corner
light and lightbar element provides strong
energy signals at the 45 degree points. |

PowerArc
LED’s provide more light with fewer LED’s |
|
| |
PowerArc
LED’s are flashed through mechanical
movement and stay on all the time, maximizing
performance. LED’s flashed electronically
must be turned off for a period of time, reducing
performance. Six oscillating LED’s do
the work of eight to twelve electronically
flashed LED’s of equal energy. |
|
|
|
|
|
|
|
| |
PowerArc LED’s produce brighter light throughout
the coverage area |
|
| |
LED’s
are typically bright to the front but weak
to the sides. Stationary LED’s must use
spreader optics (typically 45 to 90 degrees)
to increase the coverage. However, this reduces
the intensity of the light. PowerArc oscillating
LED’s permit the use of tightly focused
optics (10 degrees) to create a concentrated
beam of light that maintains maximum intensity
at every point throughout the desired coverage
area. |
|
|
|
|
|
|
|
| |
PowerArc
LED’s have less thermal degradation |
|
| |
Flashing
LED’s with electronics forces the LED’s
to turn on and off. This action causes an inrush
of electricity to the LED’s every time
they operate, reducing the life and performance
of the device. Oscillating devices allow the
LED’s to be operated at a constant current,
without harsh current spikes, improving performance
and longevity. |

PowerArc
lights are engineered to last for the life
of the apparatus |
|
| |
PowerArc
lightbars are constructed on massive aluminum
frames. The surface mounted devices are built
on zinc die cast, triple chrome plated back
plates. All lamps are standard, bayonet base
halogens. The element base plate, motor bracket,
and helical drive belt system are all stainless
steel. The bearings are sintered bronze lubricated
to operate in temperatures from -40 to 400
F. The reflectors are individually formed from
sheet aluminum, vacuum metalized, and then
hand focused once assembled. Each element is
individually powered and can be easily removed
for repair or replacement. PowerArc warning
lights are truly designed to withstand the
rigorous demands of the emergency services.
All PowerArc products come with a standard
2 year limited warranty. |

PowerArc
Products are designed with serviceability in
mind |
|
| |
All
PowerArc halogen products have a 2 year warranty
and all LED products have a 5 year warranty.
Warranties start after the apparatus is placed
in service. Field diagnostics are made easy
with removable elements incorporating simple
mechanical parts and very basic electronics.
The end user can field replace any individual
lens, bulb, LED, optic, or the entire element. |

PowerArc
Surface devices have direct interchangeability |
|
| |
PowerArc
surface mounted halogen and LED devices are
interchangeable and can be field retrofitted
in less than 5 minutes. The casework and mounting
are the same. |
