Product Overview
The TDHE Series LED Recessed Troffer is a multi-configuration luminaire platform designed for commercial ceiling systems requiring adaptable output, extended service life, and consistent visual performance across interior environments. Available in 1×4, 2×2, and 2×4 formats, the series supports uniform fixture deployment across office environments, educational facilities, and healthcare applications while maintaining alignment with standard grid layouts.
Selectable lumen packages allow light output to be adjusted based on mounting height, spacing, and target foot-candle levels without requiring multiple fixture types. This flexibility supports both retrofit upgrades and new construction installations where illumination requirements vary across zones.
The expanded CCT range from 2700K through 5000K enables precise control over visual conditions, allowing the same fixture platform to be deployed across environments requiring warmer tones or higher visibility task lighting. The system operates on standard 120–277V electrical infrastructure and integrates with 0–10V dimming systems for controlled light output.
With efficacy up to 150 lumens per watt and a rated life exceeding 100,000 hours, the TDHE Series is engineered for long-term operational consistency with reduced maintenance frequency. As part of a broader LED troffer lighting strategy, the fixture integrates into commercial lighting systems focused on predictable performance and lifecycle efficiency.

Optical and Distribution Characteristics
The PMMA lens system provides wide, diffuse light distribution suitable for general ambient lighting. Optical performance should be evaluated alongside distribution patterns and spacing criteria to ensure consistent horizontal illumination and reduced glare across the task plane.
High efficacy combined with controlled distribution allows for efficient layout planning while maintaining uniformity across varying ceiling heights and room configurations.
Installation and System Integration
The TDHE Series supports multiple mounting configurations including recessed T-grid, surface mount, and flange installation. This flexibility allows the fixture to be deployed across both grid and hard ceiling conditions without changing fixture families.
Integration with commercial lighting control requirements enables compliance with modern energy codes while maintaining adjustable light levels across zones.
Typical Applications
- Office lighting systems
- Educational environments
- Healthcare support areas
- Corridors and circulation paths
- Retail back-of-house spaces
- General commercial interiors

Commercial Lighting Specification & Buying Guides
View Commercial Lighting GuidesCommercial lighting systems are specified based on task requirements, mounting conditions, distribution control, and code compliance. Fixture selection must align with layout planning, electrical coordination, and long-term performance expectations across the application.

Lighting Layout, Spacing, and Performance
View Commercial Lighting Layout GuideFixture selection alone does not determine lighting performance; layout, spacing, mounting height, and optical distribution control how light reaches the task plane, and improper spacing or distribution can create glare, dark zones, or uneven coverage even when lumen output appears sufficient.
