Kevin Robertson Posted January 7, 2014 Share Posted January 7, 2014 Hi All, One of my venues has 4 500W codas as house lights. I am looking to either replace these with LED floods or a 500W led lamp... but they need to DIM... any ideas? Thanks Kevin Link to comment Share on other sites More sharing options...
ImagineerTom Posted January 7, 2014 Share Posted January 7, 2014 A load (about 10) of cheap RGB LED "par cans" is a cheap simple solution that will be comparable with your existing light output but with the advantage of DMX control and the ability to wash the venue with different colours / effects as needed. with change from £400 including all your cables & screws. The dimming isn't as smooth as a real dimmer but for house lighting it's more than OK. When one malfunctions just throw it away and replace. "Architectural" LED lighting or bastardised "non theatre" LED units will be more expensive, require modification and lots of time and head-scratching developing interfaces and adapters to make them controllable via your existing systems all for something which will only be as good as the LED parcan solution Link to comment Share on other sites More sharing options...

I had thought of that, but for various reasons, 1 being that I have chilli net running the house lights from 4 different locations as well as DMX over ride and neatness of running DMX and DMX controllers as well as the EOS Ti, I am looking to replace with LED dimmable.

ImagineerTom Posted January 7, 2014 Share Posted January 7, 2014 You're going to hit the fundamental problem that changing to LED within your existing setup will require you to either bodge significantly or replace chunks of your existing system.....

Thanks Kevin Even LED fixtures that claim to be compatible with lighting circuits driven off dimmers eventually snap off. To get a smooth dimming all the way to out you need to run hard power to a LED driver and use that to control the power getting to the LEDs, or use LED fixtures that take hard power and some sort of control (e.g. DMX).

the kid Posted January 7, 2014 Share Posted January 7, 2014 The chroma q inspires are designed as houselights, but cost quite a bit ... and then a bit more, but might be worth looking at depending on the budget. Is there a reason for changing from the setup ? Link to comment Share on other sites More sharing options...
timsabre Posted January 7, 2014 Share Posted January 7, 2014 Or GDS have that radio house light system. Link to comment Share on other sites More sharing options...
dbuckley Posted January 7, 2014 Share Posted January 7, 2014 Selecon have their PL LED house light system, unusual in that its RGB as well as W. Full DMX control. I'll wager that it is (a) amazing, and (b) expensive. But in the context of hard to reach locations over a long life span, its probably a bargain.

Andrew Edwards Posted January 8, 2014 Share Posted January 8, 2014 +1 for GDS Depending upon your funding status you can get free loans, subsidy or grants from Salix for energy saving projects. Link to comment Share on other sites More sharing options...

strand600X Posted January 9, 2014 Share Posted January 9, 2014 Hi all We have the GDS wireless system in our concert hall.112 fixtures. Not as expensive as you first think.Now I believe they are making a wired verson.Configured from a laptop it's so easy. bAz Link to comment Share on other sites More sharing options...
paulears Posted January 9, 2014 Share Posted January 9, 2014 DMXtothemax - those aren't dimmable by altering mains voltage, they have a knob, and there is a warning not to power them from power supplies outside the range specified, which is quite clearly mains continuous power.

gareth Posted January 9, 2014 Share Posted January 9, 2014 Like Tim and Andrew, I'd be inclined to make the guys at GDS my first port of call for something like this. Link to comment Share on other sites More sharing options...
timsabre Posted January 9, 2014 Share Posted January 9, 2014 I have heard stories (on blue room somewhere I think) that the GDS system radio comms can be knocked out by the Line6 radio mic equipment, but I have no personal experience of this.

Simon Lewis Posted January 9, 2014 Share Posted January 9, 2014 Kevin, How important is a smooth dimming response? I have a similar issue to solve in a church - existing house lights (PAR38s and 56s) run off a dimmer channel that can be controlled by a programmed 0-10V switch plate or via DMX. PAR38 LEDs wouldn't dim too gracefully at the lower end, but would certainly reduce the power costs, so I think I'll try a few and see how it works...At the moment, I'm considering Toshiba PAR38 Reflector Lamps.
