TECHNICAL FOCUS: PRODUCT IN DEPTH

With a 20' throw, I measured a beam diameter of 6'6"
and a white light illuminance of 1,029 lux (about 96fc)
zoomed in all the way. In the widest zoom position, I meas-
ured a beam diameter of 20'6" (6.25m) and an illuminance of
298 lux (about 28fc). This translates to a zoom range of
about 18° to about 54°. I took measurements at the native
correlated color temperature, which I found to be 5,277K,
but the unit has the ability to vary the CCT between 2,700K
and 7,000K.
The CQS measured 86, and the spectral power distribu-
tion curve shows peaks at about 440nm (blue), 530nm
(green), and about 650 (red). As you might expect by looking
at the spectrum, the fixture produces beautiful deep blues,
nice reds, and great yellows and lavenders, but it can also
create subtle shades of many pastels. And because it uses
additive, not subtractive, mixing, the intensity doesn’t drop
when you dial up a more saturated color and there are no jar-
ring color transitions. Like the ColorSource, the Relevé has
droop compensation, which keeps the intensity and color
constant as the LED emitters heat up and cool down. This
works to keep the color mixing more accurate.
The dimming curve is extremely smooth, just as you
would expect. (Some theatrical designers I know would not
just expect it, but they would demand it). Besides RGIL
color mixing and remote zoom, it also has a light frost, iris,
strobe, rotating, indexable gobos, and an “Ani-gobo” effect
wheel, which is, as the name implies, a cross between an
animation wheel and a gobo wheel. It has six distinct pat-
terns, but they blend into each other, so they can create
continuous, uninterrupted movement through the beam.
This gives you the option to park it on one pattern, mix with
a fixed gobo, or throw it out of focus and animate it to cre-
to the winners ate water, fire, or abstract texture effects.
of the 2016 The Relevé Spot also has a unique feature that ETC calls
“Whisper Home,” which uses absolute encoders so the fix-
ture can find home without having to go to extreme posi-
tions. This makes for a very quiet homing process, which is
awesome and weird for people like me who are used to very
noisy homing routines. It also homes very quickly —in less
than 30 seconds. And it has a menu setting that enables
you to limit the pan and tilt in case it is mounted in a
restricted space and you don’t want it bumping into scenery
or other fixtures.
The model I reviewed didn’t yet have RDM, but Matt
Stoner, product manager for automated lighting, told me,
“ETC takes the quality of RDM control seriously and didn’t
want to release the feature before it completed the months of
testing in our integration lab.” At last check, Stoner con-
firmed that Relevé Spot is now shipping with RDM.
The fixture weighs about 68lb and measures about 19"
wide, 23" deep, and 26" tall with the head focused
forward.
