LISTING: All fixtures bare an AFL-CIO/IBEW union label and are UL listed for dry or damp location. For alternative environmental certifications, please consult factory.
DRIVER: 120V, 277V, and Universal Voltage available standard. Five year warranty. Please consult factory for special driver requirements.
SHIELDING: Satin frosted and white opal lenses are snap in extruded acrylic - all optimized for max LED performance. Parabolic baffles are made from high quality optical grade aluminum and come in a variety of finishes.
HOUSING: 18 GA cold rolled steel in a pre-paint white finish. Built in individual pieces up to 8 ft in length. Individual fixtures cannot be joined in field to form continuous runs. Fixtures longer than 8 ft must be ordered as continuous runs.
GEARTRAY / REFLECTOR: Integrated geartray and reflector made from 040 aluminum in a min 92% reflectivity pre-paint white finish. Fully wired unit remains completely accessible from below ceiling.
TRIM/FLANGE: Extruded Aluminum trim is run around all 4 sides of the fixture system. Provides a clean and precise finish and is available for a number of ceiling applications.
LED SYSTEM Forum utilizes a tunable LED system capable of supplying between 460-1610 lumens per foot. To specify specific lumen output other than standard 950 or 650, drop the last digit of the per foot lumen output desired, i.e. 400lm/ft.= 40LED35

SNAP-IN METHOD LIFT-AND-SHIFT METHOD
For Snap-in Lenses, gently squeeze the sides (1) while lifting into place (2). Lens will snap into position.
For Lift-and-Shift Lenses (used on Regressed, Perimeter, and Asymmetrical fixtures), lift lens into housing (1) ,rest on point A, then lower into place (2).
TELESCOPING (OPTIONAL FEATURE)
Questions?(412) 781-5970Forecast FORUMBY
LED runs are optionally configured with a telescoping geartray and housing assembly to reach light to the end of any length installation run as well as into the corners of patterns, providing approximately 12” of adjustability for LED.
After installing beginning and middle of fixture per installation instructions, the telescoping end of fixture can be adjusted to fit the remaining ceiling opening.

FORUMMR ADDENDUM WORKSHEET
REQUIRED INFORMATION
1. Row Length: Nominal Exact Length
2. If nominal, is there a minimum or maximum length?
3. If linear lamps are included, are different lamp lengths tolerable within a row? (ie: two 3ft lamps & one 4ft lamp)
4. Enter total quantity of MR modules in row:
5. Choose MR transformer voltage: 120v 240v 277v 347v 480v
6. Choose lamp wattage: 20W 35W/37W Chip Onboard Replacement Lamp
7. See standard configurations below and choose desired lamp information. Or use sketch area to indicate
MR quantities, placement, linear lamping lengths, and single, dual or staggered lamping.
8. Indicate if MRs are on a separate switch or separate circuit from linear sections:
