Description
Portfolio Lighting LDRT3D 3" Precision High Center Beam Install-from-Below Round Downlight
Seamless Light. Installed from Below.
The 3" Round Install-from-Below Downlight delivers refined architectural illumination with clean, fixed precision. Field-interchangeable optics provide controlled beam distributions for consistent, center-aligned light. Designed for plaster ceilings, this luminaire installs from below without requiring attic access, making it ideal for remodels and retrofits, while an optional new construction mounting frame supports seamless integration in new construction projects as well.
Precision Optical Performance
Field-interchangeable optics lock into place with a simple twist and provide beam distributions from narrow spots to wide floods in 5° increments, including asymmetric options. High optical efficiency minimizes stray light, and the integral lens holder accepts up to two 2" diameter filters or lenses for added control.
VividTune fine-tuning of light
Whether you're looking to optimize productivity or simply add dramatic flair, VividTune's tunable white technology allows you to adjust the color temperature from warm white to cool white, creating an environment that fosters productivity and concentration.
