The Sense 199 product line embodies a deliberate, low-glare control system. Its standout feature is the dual-level optical control, providing exceptional visual comfort through both indirect and direct lighting distributions. Offering versatility, it comes in sizes of 2', 4', and 8', and supports continuous runs, boasting a diverse array of independently controllable direct/indirect distribution options.
The Sense 199 is a modular design that can quickly replace either the entire lower module or the optical lens of the lower module, making it convenient for customers to reduce their inventory of finished products. The Sense 199 promises to enhance the user experience significantly while maintaining top-notch energy efficiency.

Beam Angles
The Featuring professional optics from LEDIL® and KEYI, along with diffuser lens options, the system delivers precise and flexible beam control for both direct and indirect lighting.
Dual Modular Architecture
Independent up-light and down-light modules, with a fully modular down-light system supporting multiple optical and diffuser options—designed for flexibility, precision, and long-term adaptability.
Ledil Optic Lens Module
Offers a wide range of professional beam distributions for precise and versatile lighting performance:
-
Batwing – Delivers even ceiling illumination with minimal glare.
-
35° – Narrow beam for accent and focused lighting.
-
50° – Medium beam for general lighting with controlled spread.
-
80° – Wide beam for soft ambient illumination.
-
25° × 70° – Elliptical beam, ideal for wall washing and corridor lighting.
-
Asymmetric 25° – Directs light precisely along a defined axis, reducing spill light.
-
Polarized Wall Washer – Provides uniform wall illumination with reduced glare.
-
Front Polarized – Minimizes forward glare for enhanced visual comfort.
The diffuser lens delivers a wide 110° beam for both
direct and indirect lighting, creating soft, continuous
illumination ideal for general ambient applications.
Diffuser Lens Module
