34 / 38 / 45 Watt Adjustable 2x4 Troffer Light | 4250 to 5715 Lumens | 3500K / 4000K / 5000K | 100-277V
This 2x4 LED troffer is a strong choice for commercial and institutional spaces needing adaptable, efficient lighting. Its selectable wattage (34, 38, or 45 watts) and color temperature (3500K, 4000K, or 5000K) allow precise tuning for offices, classrooms, healthcare, and retail environments, especially where uniform, low-glare illumination is important. The fixture’s UL listing, 1-10V dimming, and robust aluminum and polycarbonate construction support reliability and long-term use in standard indoor settings. It is not intended for wet or hazardous locations, but excels as a direct LED replacement in grid ceilings or for surface mounting where needed.

Product Lighting Layout Estimator
Use this estimator to calculate approximate fixture count, spacing, and average foot-candles for a simple rectangular space using the selected LED fixture. Enter your room dimensions, mounting height, target foot-candles, light loss factor, and room/layout condition to generate a preliminary lighting layout.
Project Inputs
Estimated Results
Estimated average foot-candles are preliminary and should be verified with a lighting plan for project-critical applications.
Room / Layout Condition: This is a simplified room utilization factor. It accounts for room reflectance, fixture distribution, racking, obstructions, and how much fixture light reaches the work area. Open / light-colored spaces use 0.90, typical warehouses or shops use 0.75, racked or obstructed spaces use 0.60, and dark or complex spaces use 0.45.
Photometry / Simulation Note: When usable IES photometry is available for the selected fixture, this estimator uses the fixture’s IES candela data to improve the visual floor-level light distribution. When IES photometry is not available, the estimator uses a simulated beam model based on lumens, mounting height, room/layout condition, light loss factor, and beam angle.
Preliminary Estimate Only: This estimator is intended for simple square or rectangular spaces. Actual light levels may vary based on fixture optics, mounting conditions, ceiling height, surface reflectance, obstructions, controls, voltage, installation conditions, and site-specific requirements.
This estimate is a starting point. Warehouses, industrial facilities, hazardous locations, sports areas, schools, healthcare spaces, public areas, and code-sensitive projects may require a reviewed lighting layout before purchase or installation.
