LED Room Wash Ideas

[Ed_lx]

Hi everyone,

 

I am looking to replace over 100 1000w CP62 parcans (actually No. 5's) for LED and would value your input and ideas. They are lighting a large (50m x 50m) floor space from truss heights of between 6m at the perimeter and 10m in the centre of the space.

 

As I see it, I have a number of issues to address:

 

- Must be of a similar light output

 

- Must have at least 24 deg beam angle (ideally up to 37 degrees)

 

- Must be able to create subtle pastels and have a high CRI in these colours

 

- Must be able to create a wide range of saturated colours (e.g. deep blues- L120 etc)

 

I use ETC Source Four Lustre+ units and these have an excellent colour range (I hear the Lustre2 is even better) but may not have the punch. There are a decent range of other multi-chip wash units on their website, I wonder if anyone has had any experience with them?

 

I can't imagine getting the colours or CRI I need from RGB, probably not RGBW. Any thoughts on RGBAW or even RGBAWUV, are these much better or just a gimmick?

 

 

Any thoughts and suggestions would be gratefully received!

Have a look at the ETC Colour Source PAR. RGB and lime. Pretty punchy and a variety of beam shaping options via custom lens filters. Good pastel range via the lime. I've only used them in demo, but was impressed enough to buy some for a new build project I'm involved in.

ICC Hall 3 by any chance?

Open your search up from just PARs, and look at some of the cyc flood type lanterns. I'd certainly be looking for demos of some of Chroma Q's stuff, as their range includes dedicated LED houselights.

Almost any LED lantern will produce deep saturated blue, and red and green, often subjectively better than gel over a halogen source.

 

Good pastel colours are a little more challenging as is a good high CRI white. Often Simple RBG mixing is not sufficient and additional amber and/or white LEDs are used to achieve better whites and non saturated colours. The addition of lime colour LEDs is a fairly new idea and is said to be a considerable improvement, but I have not seen any myself.

Hi Ed_lx,

 

I would definitely take a look at the Prolights StudioCOB family, and would be delighted to bring them over to show you just how well they would work on site whenever suits.

 

The StudioCOB has the punch for the throw distances you are looking for, and with interchangable lenses you can swap from 30* to 15* as and when you need. There are Full Color or fixed Daylight /Tungsten versions, all of which are used daily in a wide range of environments including exhibition and conference. It is a very popular fixture, and I am sure that there are a good few people on here who will be able to vouch for it.

 

The CREE COB source in the Full Color unit gives a fantastic color range, including beautiful pastels, and the parabolic reflector in the optical system makes the beam unbelievably smooth.

 

As always with any luminaire, the proof of how well it will work for you isn't really on the spec sheet but in the beam itself. If you drop me a line with your number, I am happy to bring them over tomorrow to show you just how good they are!

 

Best regards,

 

Neil

Please let this be true!

Hi Ed, have a look at this Elation unit http://www.elationlighting.eu/en/arena-par-zoom.html

I have used these units and found them to have good colour saturation and punchy, plus you have the zoom option so can set your coverage?

may be a option if budget is tight!

 

cheers

Hi Ed,

 

If you do want to look at the Chroma Q range of fixtures they are a very good option to consider. (thanks for the recommendation Jon)

 

The one I would think would tick the boxes would be the Chroma Q Inspire http://www.chroma-q.com/products/inspire-led-house-light.asp

 

They produce a fantastic range of colour's, strong saturates through to subtle pastels. Have a good CRI value, completely flicker free for camera use and have no noisy fans that other units can have.

 

The Narrow Lens option (32 degree's) sits slap bang in the middle of your request range as well.

 

We have done a number of installs with the units throughout Europe and the US and on the website is some great examples of how they have been used.

 

If you have any questions please feel free to contact me on here or via email and we can happily arrange a demo of the fixtures on site.

If you would like to go down the Elation route I can arrange for demo units if you'd like to see them in your venue. We have a number of elation units in our hire stock and they are becoming more and more popular. thanks, Dan

Hi guys, thanks for all the ideas, sorry it's taken this long to reply!

I saw the Chroma-Q units while trawling the web, interesting to hear someone has used them in anger.

I like the sound of the Prolight units too, would be interested to see if they are powerful enough and have decent colour rendering in the pastels with only RGB.

I haven't considered any cyc flood units as I suspect these would be too wide as the throws I am looking at are up to 12m!

I like the idea of the source four par, lime is definitely the 'in' thing at the moment for smoothing out the colour spectrum, sounds worth a look.

I'm not entirely convinced I can get a full enough range of saturated colours from simply RGB, I can certainly get primary blue, but then how will I achieve indigo? As soon as I bring any red in, we start getting into magenta territory, but I'm happy to be proved wrong, as ETC seems one of the few manufacturers to produce units with additional colours.

Great food for thought!

These are pretty awesome. 12w RGBAW + UV. They do a bigger version to. A venue I work in has just bought some.
