Ali2580 Posted March 12, 2009 Share Posted March 12, 2009 I have used U.V. lights a couple of times, both cannons and strips and I personally prefer cannons. Using strips we had to use about 4 (2 on floor front stage and 2 flown cause we couldn't use FOH) where as we only needed a couple of cannons to achieve an even flood across the stage. And as jonathanhill said, yes it has to be complete dark for it to work properly. Link to comment Share on other sites More sharing options...
niclights Posted March 12, 2009 Share Posted March 12, 2009 It might not have to be completely dark. That depends on what you are trying to achieve. UV active dyes and paints will still show up very well with other light. Link to comment Share on other sites More sharing options...
Dmills Posted March 12, 2009 Share Posted March 12, 2009 One thing to remember about cannons is that they have about a minute warm up time, where tubes in a modern HF fitting will be pretty much instant on.If I cannot get real UV floods then I personally prefer tubes to cannon as the source is more diffuse and as I say they have no warm up time.

KevinE Posted March 12, 2009 Share Posted March 12, 2009 The other option is LED. They are particularly effective and are instant on/off and come with DMX as standard. Link to comment Share on other sites More sharing options...
Jamtastic3 Posted March 13, 2009 Share Posted March 13, 2009 The other option is LED. They are particularly effective and are instant on/off and come with DMX as standard. I've noticed this as well! Blue LED's in parcans have a fair amount of impact on certain UV dyes. Link to comment Share on other sites More sharing options...
Robe575xt Posted March 13, 2009 Share Posted March 13, 2009 hi, another vote for cannons! they have a more powerful source so inturn will shout louder, as others have said it could be possible to use other colours with the UV but UV scenes tend to be most effective in pitch black. Another source that I have found works well to highlight UV paints and dyes on costumes is the "wood light" effect on the colour of FX wheel found in some movers, I simply set the focus to diffuse the hardedges and point them in the general direction of where the action is!

tom_the_LD Posted March 13, 2009 Share Posted March 13, 2009 What about a combination? Couple of cannons FOH and then either a few strips across the bottom of the stage, or a fewstrips hung above the stage pointing down? Link to comment Share on other sites More sharing options...

Blue LED's in parcans have a fair amount of impact on certain UV dyes. I think KevinE meant UV LED's ? I have never tried these...strobing UV to reveal/conceal must be fun on dance events! Also a couple of things to bear in mind with strips....They can be used effectively like footlights - behind a screen along the front of the stage, but depending on the proximity to audio lines, you may get a round of 'tinks' across the PA as they turn on.

Sorry guys! Totally forgot there's the UV LED cans out there :unsure:But... I have tried just blue LED's from RGB cans and I does give you some interesting results.

mac.calder Posted March 13, 2009 Share Posted March 13, 2009 If you go for cannons - make sure they supply the dousing equiptment for them (ie Eclipse irises or shutters).... nothing worse than a naturalistic scene and someone walking into it wearing a white shirt and glowing...

Sound In Gloucestershire Posted March 14, 2009 Share Posted March 14, 2009 I have a few of the LEDJ UV Stratos effects, brilliant effects with a good throw on them, however they dont really flood, they tend to put a 3-4 metre wide spotlight where you are aiming them, so you would need 3-4 to get a good effect benefits? DMX controllable, instant UV effect and they can strobe too if required, plus of course the usual LED benefits such as low power consumption and less heat and noise. The UV Strips can sometimes make a blink blink noise when turning on Link to comment Share on other sites More sharing options...
