Dimmable UV cannons

[SceneMaster]

Quite simply can you get UV cannons which are dimmable (I didn't think you could) and if you can where from/what makes are they?

 

Thanks,

Yes, but you need mechanical dimmers.

Yes I though so... but I meant are there any electronically (opposed to DMX controlled mechanical dimmers or manually operated mechanical dimmers) dimmable UV cannons which I didn’t' think was possible. Presuming with a mechanical dimmer you can leave the UV cannon on the whole time without it causing damage to the shutters.

 

Thanks Brian useful as always ;),

Actually, thinking about it a bit further, although they aren't 'cannons' as such, you could dim UV linear fluorescents. Or, if anyone makes them, which I doubt, UV compact fluorescents as long as they were a 4-pin type tube.

What are you going to use them for?

 

A couple of movers with a "full" or very dark (181 style) blue dialled in can give a passable UV effect, especially on fluorescent materials. Blue LEDs also make fluorescent colours glow.

We need a proper UV effect as in the real stuff. This is for Honk and the underwater scene, I am the assistant LD and I am not sure weather UV is what we really need for the underwater scene. But as always the director’s spec is final and every one in the company is set on having UV for this scene so UV is what I shall give them.

As far as I know the cannons as such are discharge and you carn't dim them (as said previously without using shutters), But if you get a blacklight tube(flourie without the powdery inner coating.) and fit it to a dimmerable flourie fixture this would work. Hope is some help!

I LD'd honk and for the underwater scene and the snow scene I used mac600's and 250's in there Lee181 colour and it worked fine

Please please don't let Mr FW hear this conversation!!

 

Why do you need to dim the UVs? Switch on during the closing bit of the previous scene, and if bright enough, no one will notice until the 'normal' lights fade out.
