ARRI feedback on KOTO DIS-180 VIVID
LIGHTING PRODUCT INFORMATION
Please find a summary of ARRI’s test results of Koto’s discharge lamp DIS-180H VIVID.
All tests were conducted in ARRI’s own light laboratory located in R&D department at
ARRI Stephanskirchen, Germany.

Beside a primary test in a sphere all test were performed with latest ARRI gear and
technology. For the tests with DIS-180H VIVID an ARRIMAX 18/12 lamphead and a High
Speed electronic ballast EB 12/18 AutoScan were used.

Temperature tests:
@ 45°C temperature all test points were within limits.
@ 25°C the lamp base was below limits even at 75° tilt angle (which is not
permitted; only for reference)

Photometric tests @ 75 and 1000 Hz:
1. Sphere (all three lamps) after 0 h and 10 h
a. Power slightly below nominal values ~17500 W @both 75 & 1000 Hz
b. CCT ~6700 K @75 Hz and ~7000 K @1000 Hz

2. Illuminance and Intensity a 0 h and 10 h
a. Slight increase after 10 h (as expected)
b. Slightly higher values for 1000 Hz (compared to 75 Hz)
c. All values on nominal / reference level

3. Color metrics at 10 h
a. CCT approx. 300 K higher in 1000 Hz mode
b. CCT variation from 7500 K (max Spot) down to 6300 K (max Flood)
c. Deviation from black body curve -0,002 to – 0,007 dCP
d. CRI >95 all angles with R9 87 – 96 (max Spot)
e. TM 30-15 Rf >94 (75 Hz) resp. >95 (1000 Hz)
f. TLCI between 96 and 100 !!

The new KOTO VIVID 18k discharge lamp performed more than well in both areas –
temperature and lighting quality. While the output is already a punch the new lamp turns the ARRIMAX 18/12 into a new benchmark in terms of color rendition. Values up 100 in various metrics show the possibilities of an state of the art daylight system – driven by latest ARRI ballast technology and running in on and only the ARRIMAX 18/12 the KOTO DIS-180 VIVID did more than good.

Thanks to the entire R&D team at KOTO. The VIVID, ARRI expects an entire range of new discharge lamps.
