lightsource Posted June 1, 2008 Share Posted June 1, 2008 Hi all, We have a load of 300 /500w halogen floods, similar to this: http://www.screwfix.com/prods/86568/Lighti...ight-Black-500W Previous BR topics on high temperature gels make refrence to the Lee HT filters, however I can't find the temperature specs on their website, and I'm not quite sure of the working temperature of these lights. I'm not really bothered about precise colour matching, just looking for a basic range of colours to work with. Any suggestions appreciated.

musht Posted June 1, 2008 Share Posted June 1, 2008 Nid had the very neatest solution. Link to comment Share on other sites More sharing options...
lightsource Posted June 1, 2008 Author Share Posted June 1, 2008 Cheers Musht, Missed that one in the search. Whilst I could fabricate something like that, I have 12 of them, and was hoping for a simple solution, where they could just be gelled. It is possibly a viable option though, Link to comment Share on other sites More sharing options...
peternewman Posted June 1, 2008 Share Posted June 1, 2008 You could look at dichroics too perhaps, although I don't know how the price and range of colours would compare. I imagine this suggestion has been mentioned in the past, so I'm sure a search will give some more thoughts for or against it. Link to comment Share on other sites More sharing options...
niclights Posted June 1, 2008 Share Posted June 1, 2008 As a rough guide, I have a quote for approx £40 for dichroic cut to this size. Link to comment Share on other sites More sharing options...
GridGirl Posted June 2, 2008 Share Posted June 2, 2008 Old Pat 223 frames bent into a curve, blackwrap the sides to stop light spill, leaving a small gap at the bottom for airflow, and Lee HT gel should be fine. You will have to tape the frame to the lantern, unless you can fabricate some method of permanent attachment, but it works pretty well! It's also easier to tape the gel to the frame, as getting it into a curved 223 frame requires a lot of patience... Link to comment Share on other sites More sharing options...
The Gaffa Posted June 2, 2008 Share Posted June 2, 2008 Cheapest way is a pack of large buldog clips, Cut the gel to 1.5 times the width / height, clip to the sides of the flood. This works, but you'll need to check the clips every day. Lee filters work ok, but don't use 181, 119 as these burn out fairly fast. Link to comment Share on other sites More sharing options...
boatman Posted June 2, 2008 Share Posted June 2, 2008 Nothing to do with gels, but there are a number of safety issues here. 1. These fittings are clearly marked "For Outdoor Use Only". Have you checked that you can meet the the safe operating distances from both walls and ceiling? 2. Is the mounting metalwork sufficiently substantial to take a 10mm bolt for attaching a standard pipe clamp? 3. Is there a place to attach a safety bond to the diecast housing? IMHO, if you answer "No" to any of the above questions, you should not use these fittings in a theatrical environment. Link to comment Share on other sites More sharing options...
paulears Posted June 2, 2008 Share Posted June 2, 2008 I had some of this type and indoors they don't seem to last very long - the internal temperature is pretty high, lamp life is not that high and the front glass will melt HT gel if it touches it. The beam is very odd too - hot spots and weird edge angles. Theres no real place to attach outriggers, and the usual video thing of attaching the gel to barndoors would work - if you could fit barn doors. I reckon, that adding all this to a £5 fixture isn't really worth it. If you want colours, and decent gel capability - buy the right tool. If you want to flood an area with loads of white, bright, uneven light - then these are just the thing. Link to comment Share on other sites More sharing options...
showman Posted June 2, 2008 Share Posted June 2, 2008 As a quick fix for an INDOOR setting out the way of people: You can always remove the glass and gel it, then it probably won't burn in a hurry. Just a thought. Link to comment Share on other sites More sharing options...
niclights Posted June 2, 2008 Share Posted June 2, 2008 The glass is there to protect you if the bulb explodes. So I really don't think that's a good idea. It would not affect how fast the gel burns anyway, unless it's actually touching it! Link to comment Share on other sites More sharing options...
tokm Posted June 2, 2008 Share Posted June 2, 2008 You can always remove the glass and gel it, then it probably won't burn in a hurry. Just a thought.So what happens if the lamp explodes..? Oh look, nice hot glass falling onto people. :** laughs out loud **: Removing the glass is not a good idea! If you look at units such as coda floods (or any flood for indoor/theatrical use), there's usually a wire mesh in front of the lamp to stop any debris falling out. Also, 2nd Boatmans comments.. These floods really shouldn't be used in a portable unit fashion in a theatrical environment. Their just not designed for it & shouldn't be bodged into being usable! Tom *edit - Dam.. beaten to it by Niclights! Oh well, hopefully two posts will convince the OP this isn't a good idea!* Link to comment Share on other sites More sharing options...
lightsource Posted June 3, 2008 Author Share Posted June 3, 2008 Nothing to do with gels, but there are a number of safety issues here. Well you're post has nothing to do with gels.................If I needed to know H&S or RA details, I'd have asked for them :** laughs out loud **: I had some of this type and indoors they don't seem to last very long - the internal temperature is pretty high, lamp life is not that high and the front glass will melt HT gel if it touches it. Now that's more like it. I have 12 of these, 4 are used as stage blinders, and the others have not been used. I've swapped the 500w lamps for 300w. (But still redundant stock). The reason I want to use them is that in some of our gigs, we're a little lacking in stage illumination from the front, and I don't have the budget to purchase new toys. Paul, I appreciate you're comments about the harshness /nastiness of these , but they'll be on dimmer packs, so hopefully we'll be able to reduce some of the harshness. I'm really just looking for a 'cheap' fix for coloured FOH illumination, hopefully to complement the PAR gels. Edit..................to add.. They're not being used in a theatrical environment, it's rock bands, and 'touch wood' have never had any lamp life issues. Also I've ignored the posts on removing the glass!......Don't quite get that. Link to comment Share on other sites More sharing options...
