fbnts Posted January 9, 2011 Share Posted January 9, 2011 Hi, I'm looking at the possibility of replacing our old worn out KAM DJ250 Colour Changers to something more reliable and economical (The constant bulb replacement is a pain and with them all going they create quite a bit of heat and use a lot of power). Are there any decent narrow beam LED colour changes available that are of similar power? I have seen quite bright LED PAR56 but nothing that have a very narrow beam. We currently have 8 colour changers on two mirror balls. Tom Link to comment Share on other sites More sharing options...
timsabre Posted January 9, 2011 Share Posted January 9, 2011 I don't know of any LED spot with a narrow enough beam for shining on mirror balls. You need a really narrow sharp edged beam for the mirror ball to be effective and LED is all wide and fuzzy.I think you may be stuck with your 250W halogens for a while yet.

greenalien Posted January 9, 2011 Share Posted January 9, 2011 Might be worth considering replacing them with 150W or 250W discharge lamp fixtures - at least you won't have to keep changing lamps! Link to comment Share on other sites More sharing options...
Jamtastic3 Posted January 9, 2011 Share Posted January 9, 2011 American DJ do a static version of their x move led mover. Can't remember what it's called but it could be the x colour. A static led fixture with colour and gobo wheels. It should be ok for mirrorballs and such like Link to comment Share on other sites More sharing options...

The issue still arrises with beam angle but at closer distances, this shouldn't be too much of a problem. Link to comment Share on other sites More sharing options...

The issue still arises with beam angle but at closer distances, this shouldn't be too much of a problem. I would go with the ADJ X Color + (first link) Beam angle you should be able to change, by removing the old lens and replacing it with a new one. Its only held in there by a bit of silicone and a spring clip. Intensity wise, my X scan's (not the + version) give my Martin MX-4's a run for their money, and these are not the + version which is claimed to be brighter!

I thought we were still waiting for the first low budget LED "profile" spot. Link to comment Share on other sites More sharing options...
fbnts Posted January 10, 2011 Author Share Posted January 10, 2011 Thanks for your replies. The American DJ X-Color LED Plus looks just right. I will get one ordered to see how it matches up with the KAM. With the amount of ELC bulbs we are getting through they will pay for themself in no time! Also at 28watt are about 10% of the power we are using now. Thank you so much for your help. Tom Link to comment Share on other sites More sharing options...
timsabre Posted January 12, 2011 Share Posted January 12, 2011 Just looking at these ADJ X-Colour lights, I thought they were using an RGB LED source, but it looks like it's a white LED with a motorised colour filter wheel, can anyone confirm this?

Yes it has a single white LED source, with a motorized colour wheel. Ive got the slightly older ADJ X scan LED which has only a 20w LED, and I couldent help myself, had to pull it apart after I can plugged it in! :D (of course I unpulled it before opening it up) Link to comment Share on other sites More sharing options...

I'm not sure this is true, as colour-filtering a white LED is a really horribly inefficient way to get colours. My theory is that big white LED arrays are cheaper because more are being used in the market. RGB ones are less common so more expensive for the same power (the Luminus ones used in the Varilite VLX wash are going on for £100 each and it uses 7 of them...) Also I would expect it to be really hard to mix the RGB colours sufficiently to avoid colour fringing on gobos. Does anyone know if there any RGB-mix profiles out there?

niclights Posted January 14, 2011 Share Posted January 14, 2011 Exactly. It's a disaster and I've not seen any convincing examples yet (including the Mac 350). If you thought filtering red in a metal halide was bad.... I have not seen any RGB source profiles yet and I believe this is the primary problem the manufacturers are facing. I look forward to a VL solution. Link to comment Share on other sites More sharing options...

I downloaded the manual for the ADJ light and noted that it actually doesn't have a red on its colour wheel - presumably because there is hardly any red from the source.

Yes in my opinion a single white source is much better than a RGB one. the RGB one is more flexible in what it can do, but most of the time its utter crap and between 10 fixtures the colours are never the same.

It is kind of annoying being only limited to a 8 position colour wheel, but after having a play with some Chauvet Min Spots which feature a 15w RGB LED, I would go with my X scans any day. The "white" given by the Min spots is horrible, and none of the colours match up. and when you add a bit of haze into the air, you can see all the colour fringes. compared to the X scan, which produces a nice even beam, and when sitting next to my Martin MX-4's I can barely notice the difference!
