partyadz Posted May 16, 2011 Share Posted May 16, 2011 Hi all Looking to light a 50 cm in a marquee. Any opinions on best thing to light it with? Have either traditional pin spots or Source 4 575 26 deg, or a Source 4 Junior Zoom available. Alternatively, has anyone experienced use of the LED Pinspots? Cheers Link to comment Share on other sites More sharing options...
Brian Posted May 16, 2011 Share Posted May 16, 2011 Any opinions...Yes. Have either traditional pin spots...Yes. ...or Source 4 575 26 degToo wide. Any further than 1m away and your spot will spill over the edges. ...or a Source 4 Junior Zoom available.See above Alternatively, has anyone experienced use of the LED Pinspots?Too dim. My favourite... Link to comment Share on other sites More sharing options...
willdart666 Posted May 16, 2011 Share Posted May 16, 2011 Pin spots are what you need here. You could use the shutters on the S4 to keep the beam narrow but I don't see why you would bother if you have pin spots available. Link to comment Share on other sites More sharing options...
benweblight Posted May 16, 2011 Share Posted May 16, 2011 My favourite... "Ideally for larger distances. Been suitable for mirror ball. In the fog is particularly good the jet to see" Product descriptions as abstract and poetic as ever Link to comment Share on other sites More sharing options...
MrBoomal Posted May 16, 2011 Share Posted May 16, 2011 I always use a source 4 with an iris. As a matter of interest what is the comparable brightness between a pinspot and a s4 with a 750 lamp ? Link to comment Share on other sites More sharing options...
Brian Posted May 16, 2011 Share Posted May 16, 2011 I always use a source 4 with an iris. Trouble with an iris is that it throws away light. Shrink a beam to half its original diameter (=a quarter of the area) and you waste three-quarters of your light or wattage. So a 750W S4 becomes no brighter than a 100W unit with no iris.

RoyJ Posted May 16, 2011 Share Posted May 16, 2011 Hi There, I use a 1w led pinspot,absolutely brilliant(excuse the pun).I was a bit sceptical at first but in use it proved what a useful little lantern it is.It even came with a choice of two lenses,definately the way to go.If memory serves, it cost £40 approx.Hope this helps,regards Roy.

Brian Posted May 17, 2011 Share Posted May 17, 2011 So a 750W S4 becomes no brighter than a 100W unit with no iris.That should of course read '200W'. Link to comment Share on other sites More sharing options...
hydrus Posted May 17, 2011 Share Posted May 17, 2011 In our theatre I use 2kW ADB 13°-36° ellipsoidals with an iris. Used it for different mirror balls from 50cm to 1.2m At least two and sometimes 3 or 4 (depending on the gel) The beams realy punch trough the haze and all the other beams with that much power.The big advantage to pinspots in my opinion is that you can hang the light in a range from 5 to 10m away and perfectly light the complete diameter of the ball to make as much beams as possible and cut all the spill light away perfectly.

Brian Posted May 17, 2011 Share Posted May 17, 2011 The other thing to remember with mirror balls is that for the best effect you want as narrow a beam angle as possible to start with. That's a 'narrow beam angle' not a 'narrow beam'. For example, a beam which is diverging at 30 degrees, even if focussed to just cover the ball, will continue to diverge at 30 degrees once it's been reflected.

paulears Posted May 17, 2011 Share Posted May 17, 2011 Brian - not one to quibble with your maths, but ... a 750W Source 4 is exactly the same brightness as a severely shuttered down one. The light level at the middle of the beam doesn't change. Link to comment Share on other sites More sharing options...

The light level at the middle of the beam doesn't change.Agreed. What I was trying to get over, badly, was that shuttering down a lantern reduces the total amount of light coming out of the front. Given the choice it's better to either move the lantern closer or to use a narrower angle unit. Link to comment Share on other sites More sharing options...
LXbydesign Posted May 17, 2011 Share Posted May 17, 2011 In our theatre I use 2kW ADB 13°-36° ellipsoidals with an iris. Agreed! Great for a theatre, but I dont think you want to be lumping a 2K ADB up in a Marquee. Personally, I use Source 4's with the most narrow lens or an iris. If your feeling really posh, you could use a Clay-Paky Sharpy B-) They are fantastic for mirror balls! Link to comment Share on other sites More sharing options...

Given the choice it's better to either move the lantern closer or to use a narrower angle unit. A pinspot is by far the best solution for lighting a 50cm mirrorball as per the OP's situation. However when lighting a 200cm mirrorball from a throw distance of 25 metres I would say there is no better solution than a source four with an iris in. Unless of course you have moving heads to use! <_< http://img193.imageshack.us/img193/9103/mirrorballv.jpg Uploaded with ImageShack.us Link to comment Share on other sites More sharing options...
GridGirl Posted May 17, 2011 Share Posted May 17, 2011 When stuck with no other option (don't ask!) I used a pair of ancient Selecon 1kw PCs, spotted down as far as they would go - admittedly they were hanging pretty close to the mirrorball, but the end result was fantastic - far better than I had expected!
