differces between par HMI and copact HMI
Posted 28 May 2008 - 03:31 AM
It's very basic question, which feels kind of stupid to ask.
but could anyone explain the qualities of par HMI lamps?
In general I lost track in what are differces between par HMI and copact HMI.
Which are good for what....
will be happy to get some advice

Many HMI par lights also use the newer bulbs as well.

Par lamps (including tungsten) best feature is that they kind of have more bang for the buck. They have a very powerful beam that does not have much spread. Now that beam can be used to give you an exposure (and often a very hot one) without that spread.
But they do come with lenses to vary the spread. The lenses offered are usually a narrow spot, medium, wide, super wide, (and some HMI pars have a fresnel like lens). HMI pars have the lens to change and tungsten pars usually needs to change the whole bulb to change a lens.
But whether one uses a par or fresnel depends on the use of the light.
