RGBA vs RGBW

I have LED wash fixtures and I regret buying RGBW instead of RGBA, Without the amber you are severley limited on the colours you can mix. The extra white allows you to slightly ple out a colour - but that is all. The ideal is RGBAW. The only question then becomes how many LEDs of each colour. My fixtures have forty eight 3W LEDs in each unit.

For the same cost of the Slim Pars you bought, you can get Blizzard's Puck RGBAW fixtures. Also a slim style par with feed through DMX and AC.

The Puck

Bill, the Puck draws about 10W of power?

The web site says there are 198 1/2 watt LED's...

The "1/2 watt" rating on those LEDs is a lie. 10mm LEDs are advertised as "1/2 watt" and 5mm as "1/4 watt". They don't come near that consumption.

You are correct Soundlight, the .5W rating is obviously a misprint, intentional or not. This small LED device is not a 100W luminaire...

The soon-to-be introduced Apollo Multiform 1310 produces 530 lumens using 307 x 5mm (60mW which is .06W) LEDs with a total power consumtion of 18W. Onboard electronics consume a small amount of power, so the 18W is not pure LED power.
The math looks like this: 307 x .06W = 18.42 Watts

RGBW or RBGWA LEDs in a moving head fixture?

This feels like my first post here and I have a question.


In a moving head wash fixture(led), what would be the importance in having amber LEDs in the fixture if it was a RGBW{A}?


Which fixture would you choose if they were identical except for one had red, green, blue, white and the other had red, green, blue, white, and amber. Is it worth the extra money to get the lights with amber LEDs in them?

-or- a simpler question what is your opinion on how important amber is in color mixing?

These would be used as a stage wash/spot light and possibly controlled by an ETC Ion.


Thanks!

Re: RGBW or RBGWA LEDs in a moving head fixture?

Brent, I think it is a bit of a toss up for you, and it also depends on how saturated the Amber is. For instance, I just finished a tour where I had Color Blast TRXs which offer both white and amber, I would use them to make saturated colors paler. If I wanted it to be a cooler color I would lower saturation with the white, if I wanted a warmer color I would use the amber. I never found myself using either alone, only in addition to other mixed colors.

My gut instinct would be, if you use them for concerts go with just the white, if you do dance/theatre mostly add in the Amber, or get a fixture with amber instead of white. But the best way for you to be able to tell if by demoing two lights next to each other and seeing if having the extra Amber lets you make colors you couldn't without.

This. Of course the best way to hedge your bets is to use RGBAW, but as you've found, this comes at a cost of both purchasing and programming the fixtures.

For more, see the article "Color control of LED luminaires" by Robert Bell beginning on page 28 of Protocol - Summer 2013 digital edition .

Re: RGBW or RBGWA LEDs in a moving head fixture?

I would chose the latter. It should be brighter, the audience won't see all the different LED colors and you won't have the multiple color shadow problems. The first fixture might give you a slightly better white, but it's still going to suck compared to a tungsten source, and you won't be using much white anyway lighting concerts and dance.

==============================

Is it worth the extra money for the Chauvet fixture or is it only marginally better from just looking at the specs?... Im mainly looking for opinions to help determine the fixtures I will buy. Thanks!

Re: RGBW or RBGWA LEDs in a moving head fixture?

The elation fixture is a gag fixture, all it does is a very narrow beam of light, its good at what it does, but that is all it does.
