They tend to have a longer body and a motorised mirror, which reflects the beam at the head of the light. Moving head mirrors or 'scanners' are another variation of the popular moving head spot. Wattages range from 50W for a PAR16 up to 1000W for a PAR64. Dividing the given number by 8 will give you the diameter of the bulb in inches.
Parcans come in a range of sizes starting at a PAR16 all the way up to PAR64. Barndoors may be used on the front of the fixture to control spill. The one exception is the VNSP bulb which produces a round beam. The bulb may be rotated by hand in the rear of the unit to adjust the direction of the oval beam. A variety of lens and bulb combinations are available:Īll PAR cans produce a soft, oval beam which is suited to washing large areas or aerial beam effects. To do so requires changing the entire bulb and lens unit. The nature of its construction means that the beam angle on a parcan is not immediately adjustable. It is a sealed unit consisting of bulb, reflector and lens all as one unit which is then placed inside a metal tube ‘can’. A PARCAN or PAR is short for ‘Parabolic Aluminized Reflector’
