Subject: [SML] Interpreting LED color fixture photometrics
References: <1847872971.887982.1780311671491.ref@mail.yahoo.com>
Message-ID: <1847872971.887982.1780311671491@mail.yahoo.com>

I am unsure how to interpret the photometrics for LED fixtures that have many colors. E.g. RGBAL+UV. I am guessing that if the photometrics are provided, that they give Lumens or Lux at full brightness for each color. Which of course, leaves you guess about the brightness if you adjust for a warm white. Then, many fixtures also reduce the wattage for the various colors if you bring each color up to 100%, because that would prevent overheating.

Another issue is for lower-end fixtures designed primarily for the DJ market. They may only provide the wattage for the LED chip. And it would be normal for that to be exaggerated. 

Any ideas about how this is handled?.. especially the more professional theatrical light?

Always seems like a wise choice. I?ll suggest this list to the pmf and maybe we?ll see an influx of new TDs. Or the same old ones:)

In addition to the stagecraft list, the USITT Technical Production 
Commission set up a Google List that went live in April (I think). There 
is a moderating process for joining, I am not sure it it is limited to 
USITT members, I do not see anything so my guess is it is not.

I do recall a specific TD Forum that was parallel to the PM Forum...would have been 10-15 years since I last partook, and last I knew Brian Phillips at Ohio Northern University (and formerly of the Goodman) was one of the people trying to keep it going. It just didn't seem to have enough activity to keep momentum.

I don't know if Brian is on thisy here mailing list (which is decidedly VERY different in function and content).
He should be easy to track down at ONU tho.

Best of luck,
Scott 'Hop Along' Henkels
