1) Housing - Mounting pan is of 20-gauge
galvanized steel. Plaster frame has a fixed throat
of 1 3/16" to accommodate double-thickness
plasterboard. Thru Wire junction box is 16-gauge
galvanized steel. CSA listed for thru wiring (2 in
and 2 out at 90° C) and has 7/8" knockouts.
IBEW Union Made
2) Wattage & CCT - Wattage options are 12W,
16W or 20W. Available in 2700K, 3000K, 3500K
or 4000K color temperatures for 80CRI or 90CRI.
3-Step MacAdam Ellipse.
3) Dimming - Basys LED II is available with 0-10V
Dimming driver standard, with 10% dimming. DALI
driver not available for use in a CP Chicago Plenum
housing. 1% dimming with the Lutron HiLume A
series, and 1% dimming with a DALI driver. For nondimming installations, the standard 0-10V dimming
driver will be provided, and the dimming control
wires can simply be capped off at installation.
Compatible 0-10V Dimmers:
- Lutron DVTV
- Lutron NTFTV
- LEVITON IP710-DLZ
- Wattstopper/Legrand ADF-120277
- Osram 45561 - LC-SL3W-TVWBX/UNV
4) Driver - The driver can be removed through the
throat.
Lower Reflector Finishes -
5) Mounting - Rigid mounting brackets provide 2”
vertical adjustment from inside the aperture. Brackets
accommodate One-Piece Universal Mounting Bar.
(mounting bars ordered as an optional accessory). For
installation in TechZone 6” ceilings mounting bars are
not required as mounting brackets can be adjusted to
slide onto the ceiling grid.
6) Reflectors - Upper Reflector - Reflector is anodized aluminum of high-specularity, vacuum metalized or
electropolished designed to provide highest efficiency
and effective beam distribution. Wide beam uses one
piece optical lens that obscures direct view of the LEDs
and enhances light distribution. Medium beam uses
clear lens to achieve and enhance light distribution.
Lower Reflector - Lower reflector provides optical
and physical cutoff with two options: 45 degrees or 55
degrees. Aluminum lower reflector is designed to provide
an iridescent-free finish.
Clear Specular - Highly polished post-anodized
finish with dark light appearance. Precise light
distribution and glare limitation provides highest
lumen output.
Clear Semi-Specular - Architectural visual identity
is provided while maintaining precise directionality
of light.
Matte - Soft, diffuse, evenly illuminated surface provides a congruous appearance between the downlight
and the ceiling.
White - Zumtobel White painted finish blends well
with typical White painted ceilings.
7) Life - 50,000 hours, L70.
8) Weight - 5 lbs.
