Lens Options and Light Distribution
Four lens options are available to match the distribution to ceiling height and room geometry:
| Lens | Profile depth | Distribution | Best suited for |
|---|---|---|---|
| Standard | 4.439" | Balanced | General commercial offices and institutional spaces at standard ceiling heights |
| P90 Wide | 5.173" | Wide | Higher ceilings or larger spaces needing broader horizontal spread |
| P95 | 2.999" | Narrow | Lower ceiling heights or focused task areas requiring tighter control |
| P95(W) Wide | 4.875" | Wide | Wide distribution with a shallower housing profile |
Lens selection affects the lumen distribution pattern but not the efficacy rating. Consult the spec sheet photometric data to match the lens to your required foot-candle levels and uniformity ratio.
CCT, Tunable White, and Dimming
CCT selectable: The field-selectable CCT switch allows the installer to set the color temperature at installation from the options in the specified group. Group 1 covers 3500K, 4000K, and 5000K for standard commercial environments. Group 2 extends the range to include 3000K and 6500K for projects requiring warmer hospitality tones or bright daylight output.
Tunable white (2765KT): When the tunable white configuration is selected, the fixture ships with separate 0-10V wiring for both dimming and CCT control. The control wire colors are: Purple (Dimming +), Pink (Dimming -), Orange (CCT +), Brown (CCT -). Use a tunable-white compatible control system. Consult the factory for compatible control options.
0-10V dimming: Standard across all configurations. Integrates with occupancy sensors, daylight harvesting controls, and building automation systems. The fixture operates from full output at 10V down to minimum dim level at 0V.
Emergency Battery Options
Optional emergency battery packs allow the troffer to maintain illumination during a power outage. All EM packs are integrated into the fixture housing for a clean ceiling appearance.
| Code | Description | Output | Runtime |
|---|---|---|---|
| B39 | Standard EM battery pack | 10W | 90 min |
| B39(20W) | High wattage EM pack | 20W | 90 min |
| 347…B39 | 347V EM pack | 8W | 90 min |
| 347…B39(20W) | 347V high wattage EM | 20W | 90 min |
| B39(SD) | Self-test EM (instructions included) | 10W | 90 min |
| B06…B39 | Cold weather EM (to -20°C) | 10W | 90 min (14W output) |
| B39(2HR) | 120-minute runtime EM | 10W | 120 min |
| B39(xx) | Specified EM (customer-selected brand and model) | As specified | As specified |
For Canadian installations requiring 347V operation, confirm the EM pack matches the fixture's input voltage configuration. Self-test models include printed instructions; digital copies are available on request.
Where to Use It
- Corporate offices: 2×2 or 2×4 at 3500K to 4000K with 0-10V dimming and occupancy sensor integration for energy code compliance and flexible zone control.
- Educational facilities: 2×4 high-output configurations for large classrooms. CCT Group 2 allows 3000K for relaxed learning environments and 5000K for alert task work at the same fixture.
- Healthcare environments: High efficacy and uniform distribution reduce visual fatigue in clinical spaces. Emergency battery packs support life-safety lighting requirements.
- Retail and commercial spaces: Tunable white (2765KT) allows color temperature to shift through the day, matching merchandise presentation to customer traffic patterns.
- Government and institutional buildings: ETL and FCC certifications support specification compliance. 347V input option covers Canadian electrical systems.
- Conference rooms: Tunable white with a compatible control system lets occupants shift from a cool 5000K presentation setting to a warmer 3000K collaborative tone.
Installation Notes
- The fixture installs into standard 9/16-inch and 15/16-inch T-bar grid ceiling systems. No special grid modification is required for standard configurations.
- An optional surface mount frame kit converts the recessed fixture to a surface-mounted luminaire where grid ceilings are not available.
- An optional suspension kit allows the fixture to hang below a hard ceiling or structural deck.
- For 20×60 (500×1500 mm) and 30×30 (750×750 mm) filler pan configurations, standard and C79 full-length LED options are available. Confirm dimensions against the filler pan drawings in the spec sheet before ordering.
- Set the CCT switch before the fixture is powered on. For tunable white units (2765KT), connect the 0-10V CCT control wires (orange/brown) in addition to the dim wires (purple/pink).
- Installation should be completed by a qualified electrician in accordance with local electrical codes and the National Electrical Code (NEC) or Canadian Electrical Code (CEC) as applicable.
Frequently Asked Questions
What is the difference between CCT Group 1 and Group 2?
Group 1 provides 3500K, 4000K, and 5000K, which covers the most common commercial office and institutional ranges. Group 2 extends to include 3000K (warmer, hospitality) and 6500K (daylight, task-intensive), giving five selectable temperatures. Specify the group that includes the CCT range your project requires.
Can I use this troffer with a standard wall dimmer?
The Gen 8 uses 0-10V dimming, which requires a 0-10V compatible control device. Standard leading-edge or trailing-edge Triac wall dimmers are not compatible. Use a 0-10V dimmer, occupancy sensor, or building automation interface that outputs a 0-10V control signal.
Does the TAA14 fit a standard 1×4 ft T-bar grid?
Yes. The TAA14 is designed for standard 2-ft module T-bar grids in a 1×4 layout. Confirm the grid T-bar width (9/16-inch or 15/16-inch) before ordering.
Is the emergency battery integrated or remote?
All EM packs listed are integrated into the fixture housing, keeping the ceiling appearance clean. There is no separate remote driver box required for standard EM configurations.
What does the C79 full-length LED option change?
The standard 20×60 and 30×30 configurations have LEDs positioned within a shorter active zone. The C79 option extends the LEDs to the full length of the fixture for more uniform edge-to-edge illumination. Refer to the filler pan drawings in the spec sheet for the dimensional differences.
Does the tunable white fixture require a special control system?
Yes. When ordering the 2765KT tunable white configuration, you need a control system that outputs separate 0-10V signals for dimming and CCT. A standard 0-10V dimmer will operate the brightness but will not control the color temperature. Consult the factory for a list of compatible control options.
