Par cans

[lightingyoung]

Hi all

 

I am looking into hiring some par cans but I can only find 1k ones are there any other type but which use less power?

 

Many thanks

I am looking into hiring some par cans but I can only find 1k ones are there any other type but which use less power?

They certainly come in various flavours:

 

Par 64 can use 500W bubbles, and there are Par 56 (normally 300/500W) and the smaller, (and thus less powerful) Par 36 and par 16.

 

Try the BR Wiki.

Hi,

 

Yes there are a range of different PAR cans that have a variety of different lamps available.

 

If you want to hire PAR 64s, you could ask that they have 500W lamps fitted.

 

For example. CP88 is the 500W equivalent of CP62 (a medium flood 1k Lamp). This is a sealed beam lamp, much better than the raylite equivalents (a bulb mounted in an unpleaseant reflector).

 

You could also hire ETC Source Four PARs (These are available as 575W versions and have interchangeable lenses for spread adjustment).

 

If 500W is still too much you could look at PAR56. These have some 300W lamps available.

 

Most hire shops will be able to help if you ask when you give them a call. You should look at the FAQ here: http://www.blue-room.org.uk/index.php?showtopic=3369

Good Luck,

There is an alternative. Like stated before, you can use CP87s. The ETC source four pars are good, however I find their beams to be not as crisp as the Par 64s.

Just as a query,I once heard of a 2kw Par Lamp,google doesnt reveal anything for me.

Just wondered if such a thing actual exsists?

2kW PAR?...mmmh. I think the heat generated would cook the ali coating and the glass. I know that GE have produced 1200W versions, but I think that is as far as it gets.

PAR means parabolic aluminised reflector so you can theoretically get massive lamps. Doesn't have to be the traditional can.

Don't forget the PAR originally had a different result for the acronym.

 

Precision Aligned Reflector - the design patent allowed for different lense set-ups to produce beams that were not spherical or circular -but had a controlled beam pattern that could have hot spots, dark areas, extra brightness at certain points in the beam etc. The older solution was to have a reflector, a lense and a replaceable lamp - mechanical tollerences required alignment after a lamp change. The sealed beam solution enabled greater accuracy. Pretty vital in an aircraft landing light, for example. Up until then, replacing a lamp required using a calibrated jig to reset the angle - not a simple task.

 

In the context we are talking about, we are only really talking 64 or 56 - so increasing the power is a big problem - heat and pressure would go up - I'm not qualified to state that a 2K isn't possible, but to me, seems unlikely without increasing the cooling and weight - without increasing size. No doubt somebody will do it, but I can't quite see what for. A 1K PAR64 is pretty bright already. - more light will make gels last even less time?
