man without a van Posted January 27, 2009 Share Posted January 27, 2009 I need to use some UV light in a dance Piece, im using it in a pretty small theatre so it doesn't have to be mega powerfull but I was wondering what was the difference between the gun and the flood?

glenn@KC Posted January 27, 2009 Share Posted January 27, 2009 I suppose it does what it says on the tin. If you want to flood the stage with UV light then use a flood, if you need a specific area of the stage lit them point a UV gun at it.I’m sure others will talk of beam angles and controlling the UV light (if that is possible) but my advice is work out what the UV is lighting.In my experience it is far better to have a small amount of UV light on people wearing cloths that react well to UV or a set that is painted with UV paint then Loads of UV lights on nothing that shows it up. Hope that’s helpful Link to comment Share on other sites More sharing options...
sleah Posted January 27, 2009 Share Posted January 27, 2009 I only have UV experience from a D.I.S.C.O. point of view, but I'm thinking you need UV cannons. UV tubes are great for disco, but in a theatre you would end up flooding the entire auditorium too! Which might be a laugh for the crew... anyone who remembers clubs/discos in the 70's/80's will understand ;) These LED UV's may be an option? I'd be also keen to hear of anyone's experience with them, apart from disco Cannons however aren't exactly controlable, it's on or off (Definately NOT via a dimmer!) and take up to five minutes to get to full power. EDIT: probably OK switched via a switch pack Link to comment Share on other sites More sharing options...
confused Posted January 27, 2009 Share Posted January 27, 2009 like these guys said, it depends on what you what to light. A flood will have less intensity but cover the whole stage (and everywhere else), where as a gun will just blast a small area usually with a higher intensity. So it depends. It is possible for example to put a UV gun on a stand and use it similarly to a followspot if you're focussing on one or a few dancers moving about, but it probably will take time to warm up too. So work out what you're trying to illuminate with the UV and pick the lantern you think will do the best job, either a whole stage of often weak UV or a concentrated blast in a small area.

sleah Posted January 27, 2009 Share Posted January 27, 2009 It is possible for example to put a UV gun on a stand and use it similarly to a followspot Assuming you mean cannons..... the beam isn't that tight. If you placed it in the 'normal' FS position, it would light the whole stage....... badly They would be best placed over the stage. Even the closest FOH bar would light quite a large area. Now, I wonder if the 'UV' filer in a mover/scan would give the desired effect???? Link to comment Share on other sites More sharing options...
Sound In Gloucestershire Posted January 27, 2009 Share Posted January 27, 2009 one important thing to remember is that UV lights need time to warm up! Especially the cannons, if you only need this for a short piece, then consider the LED UV Effects I have 2 of the LEDJ UV Stratos (made by prolight about £100 each) For a stage you would need 2 or 3, they have a good throw on them but will only spread a few metres (not a flood!). The advantage is that they fire up instantly at full brightness and can be DMX controlled!! Link to comment Share on other sites More sharing options...
smalljoshua Posted January 27, 2009 Share Posted January 27, 2009 Or have a look at UV Fluorescent fittings. These seem pretty standard where a quick lamp on time is needed. Josh Link to comment Share on other sites More sharing options...
mooly Posted January 27, 2009 Share Posted January 27, 2009 I need to use some UV light in a dance Piece, im using it in a pretty small theatre so it doesn't have to be mega powerfull but I was wondering what was the difference between the gun and the flood? Do you mean UV cannons (Cannon shaped), vs uv low bay type lamps (square shaped fitting)? To be honest I think 2 uv cannons would do you fine. Again the issue of control comes up! Ideal world would be have them pluged into an independat supply, and put DMX shutters on the frount of them! So you power them up 5 mins before they are needed and keep the shutters closed, then plot in a cue that will open the shutter at the required time. Reading your profile I notice you are a school tech, so maybe that would be a little beyond budget, I guess a weeks hire of the cannons plus shutter could easly reach £200-300. So maybe buying some DMX LED units maybe more viable! Perhaps ring round a few companys and see if you can get one on demo to see if it meets your needs? Hope that was of help!

glenn@KC Posted January 28, 2009 Share Posted January 28, 2009 Reading your profile I notice you are a school tech, so maybe that would be a little beyond budget, I'm not trying to go off topic but I did want to say I'm a Technician working in an independent school and for years I worked in various pro theatres of different sizes and I have to say I never had the sort of budget I have now. School fees are far more reliable then ticket sales. I’m looking to use UV in a show coming up and was just wondering, if I find a UV cannon has too much of a kick could I just calm it down by sticking a gel to the front of it? I just wondered if any one out there has any experience of this. Thanks Link to comment Share on other sites More sharing options...
