					Par Can Lighting
Par Cans are possibly one of the most widely used pieces of lighting
equipment you will ever find. Traditionally used for stage lighting, they
have progressed to become popular lighting solutions for displays, retail
outlets, band & bar lighting and occasionally even used around the home
to hi-light areas of interest!
Why are they so popular? Probably due to their versatility! Available in
a range of sizes, with a choice of fittings they can near enough fit into
most applications. The Par lamps are offered in a range of beam spreads,
normally 'spot', 'flood' & 'standard' meaning you can choose what effect
you want for your individual can. Alternatively you can have further
control of the light beam by attaching barn doors allowing you to adjust
the direction of light on separate performances. In addition to this
colors can easily be changed with the use of gel frames & coloured gel
filters.
Progressing on from standard Par cans and with the development of LED
technology there are now also a wide range of LED Par Cans available on
the market eliminating the need for replacement bulbs, gel filters and
with many offering simplistic control from the actual unit they are a
popular choice for low maintenance requirements.
There are many size Par cans available and it can be difficult knowing
what Par can to go for. To start with; the numerical reference they use
is an indication of their size. For example you can get PAR16 cans and
you can get PAR64 cans. The number quoted relates the diameter of the
bulb in 8ths of an inch. So a PAR64 can takes the PAR64 lamp which will
be 8 inches across.
Ok so we understand the sizing of the Par lamp but what is most suitable
for what application? For hi-lighting display areas, shop use or in bar
set ups normally PAR16-PAR30 cans are sufficient and can be directed to
hi-light your required area. For illuminating small stage areas such as
in pubs and for general background lighting the PAR36-PAR46 are normally
used. Then finally for large stage areas, rock bands & theater lighting
the PAR56-PAR64 cans prove most popular. It is important to remember that
the number of cans you will require will very much depend of what effect
you want to achieve and how larger an area you wish to cover. Sometimes
you are better using multiple smaller cans along one area than trying to
achieve more light with fewer large cans as this can cause an
overpowering flood effect (not to mention intense heat in one area).
When using standard Par cans rather than the LED version, users should be
aware that the fittings can get extremely hot. This is particularly the
case with larger cans and extra caution will be required if using the
floor mounted types. In certain situations when inexperienced lighting
technicians may be accessing the lights, such as in schools and youth
theatre groups the LED versions may be more suitable as they generate
very little heat.
