ONSTRUCTION
Cûrv Plus Liso is a high performance indirect luminaire with a solid or
perforated housing constructed of a heavy 20-gauge steel body with a 9
1 2 wide by 2
1 2 high profile in housing lengths of 4 , 8 , or 12 lengths. Fixtures are
available with one T5 or T5 HO lamp or two T8 lamps in cross section for
mounting at 12 from the ceiling plane to the bottom of the housing. Mounting
points maintain convenient, predictable locations. The exact shape of the
housing is maintained by the use of a patented inner die cast plate at each
fixture end (patent 6,796.676 B2) throughout the run to prevent snaking. The
housing is designed to wrap around the plate and secures on top with
concealed screws to ensure housing tolerances are consistent.

PTIONS
Cûrv Plus Liso is available with either a solid or perforated housing. Three
end cap selections are available. The standard is a flat end cap. Optional
end caps include a shallow, elongated end cap which creates an illusion that
the product is extremely slender (SCE) or an end cap which rounds off the
end for an elongated oval effect (BN). Housing and all painted parts are
treated with a multi-stage phosphate prior to finish. Parts are then finished
with a white powder coat for maximum consistent coverage and longevity.
Other colors may be specified; refer to page MTX-1 or contact your local
Alera Lighting representative.

OUNTING

EIGHT
Cûrv Plus Liso is designed to provide smooth ceiling gradients at 12 suspension lengths, measured from the ceiling plane to the bottom of the
housing, but may also be suspended at longer lengths with excellent
distribution uniformity.
M
OUNTING
A 12 adjustable Y cable hanger is standard to facilitate ease of installation when
mounting 12 from the ceiling plane to the bottom of the housing. Longer cable
lengths are also available. A straight (standard) or optional coiled cord is available
for feed locations. Cover plates are provided to shield the ceiling cutout for feed
and non-feed mounting points. All fixtures are suspended in easily predictable
increments and must be supported at each fixture housing end. Refer to the Cûrv
Plus Liso TID sheet for actual hanging points with specific row information.

LECTRICAL
All fixtures bear appropriate UL or CUL labels. Fixtures are prewired with
small case electronic T8 or T5 ballasts and are available in 120 or 277
volt. All fixtures are wired for single circuit operation as standard.
Additional circuits can be supplied as an option on the two T8
configurations; see ordering guide below.

I N G S H A P E , VERSATILEOPTICS Structural Excellence
Nevis and Nevis Plus Liso are engineered and manufactured for
maximum strength, smooth installation, and structural excellence.
Aleras patented die cast inner joiners (patent #6,796,676 B2)
assure straight rows. Tongue and groove connections prevent
light leak. Simple plug and play wiring facilitates effortless
installation. Easily adjustable cable yoke hangers maintain a
low and pleasing profile to augment the slender 2 housing depth.

Low Ceiling Heights
Low ceiling heights no longer preclude the
use of attractive architectural fluorescent
lighting. Nevis Plus Liso incorporates a
revolutionary light delivery system to
spread light evenly above the luminaire,
minimizing hot spots of light when
mounted close to the ceiling. By providing
a choice of either T8 or T5/T5 HO lamp
and ballast technology, the Liso system will
adhere to any projects standard lamp
specification. Nevis and Nevis Plus Liso
allow a consistent aesthetic to be carried
throughout a facility even when ceiling
heights and performance requirements vary.
Nevis is a unique new shape with
planes, angles, and flowing lines that
taper exquisitely into a superbly narrow
edge. This intriguing design adds visual
interest to offices, schools, universities,
and health care facilities. Combining style
with function, Nevis uses both direct and
indirect lighting to increase visual comfort
and create a refreshing, modern ambience.
