Dear all,

 

What's a good alternative to a 10K or a 5K Tungsten Molebeam? We had two on our lighting package, but thats not the case anymore, since one of them is going out. The desired effect is a sharp parellel beam of light shined through a window frame for a "spread of light".

 

The shoot is in Hungary. There won't be any Xenon arc lamps available.

 

Thanks

- Ben

Perhaps a HMI Par with only the safety glass will give you a bit of a punchy beam. Not as tight and contained as the molebeam.

Another alternative is to spot up a large lamp into a 4x4 mirror from a bit of a distance. This can give you quite a hard directional beam.

You could back up a 20K tungsten if you want the spread (and pull the fresnel if you don't need the brightness), or you can try a 10K or 5K tungsten par if you want the punch, but without the spread and without really parallel rays.

 

Otherwise, you are really talking about lights with projection lenses or xenons.  I've clustered Source-4 Lekos, for example, with narrow lenses like 19 degrees, and as long as the lamps are all pointed to create parallel rays, it looks like one beam that was broken up by passing through something like a tree (of course, on the floor you see multiple circles of light.)  A Super-Trooper 2K theatrical spot light would also create this sort of effect, or a xenon that was gelled to tungsten.
