Flush Mount
Kurt Versen’s flush mount fixtures eliminate overlapping
flanges and lock into the ceiling for a unique, finished
appearance. A clean, uncluttered ceiling emphasizes the
attention to detail, enhancing the impact of the interior
environment. It is a factory installed option with a proven
installation technique.
Optics and Applications
An ellipsoidal primary reflector and a parabolic shielding
cone use a horizontal lamp to produce a medium-wide,
smooth pattern in tenant spaces and other locations with
low to medium ceiling heights.
Design Features
Shallow depth design accommodates tight plenums. Flush
mount design resists cracking and chipping by mechanically fastening fixture to drywall. To simplify installation,
three adjustment mechanisms adapt the fixture to ceiling
conditions. Adjustable mounting rails fit different support
systems and accommodate ceiling thicknesses from 3/8"
to 7/8". Maximum extension is 26". Top or bottom service.
Finish
A specular clear Alzak cone is standard. Optional
colors and Softglow® finishes are available. Housings
and structural parts are painted optical matte black to
suppress stray light leaks. Steel parts are phosphate
conditioned for corrosion resistance before painting.

Notes
1 Data on all charts calculated with a clear specular cone finish.
2 Specular cone multipliers: Gold x .98, Wheat x .97, Pewter x .86,
Mocha x .86, Graphite x .83, Titanium x .83, Bronze x .80.
3 Softglow® cone multipliers: Gold x .89, Wheat x .87, Pewter x .73,
Mocha x .75, Graphite x .70, Titanium x .70, Bronze x .68.
4 Single unit Datachart pattern diameters are determined by the number
of degrees from each side of nadir. Therefore a 15° diameter represents
a total 30° pattern width at the work plane 30" above the floor. Footcandle
values are at the edge of that diameter.
5 Datachart spacing is rounded off to the nearest foot.
6 Data by IES methods. Compact fluorescent data vary due to lamp
lumen differences, power input, burning position, ambient temperature
and ballast characteristics. A modification factor should be applied.
