STRADA-2X2-TF - Controlled tunnel lighting with increased perception

Related Products

LEDiL introduces a new member to the STRADA-2X2 module family, asymmetric STRADA-2X2-TF designed especially for tunnel lighting applications. It’s strongly directed counter beam obtains higher cd/m² efficacy with less lumen, and increases perception of the objects facing driver, by increasing negative contrast between street and vertical surfaces. STRADA-2X2-TF works with small high power LEDs, but also with some of the bigger LED’s with flat profile such as Luxeon Mz.


  • Designed for tunnel lighting applications with counter beam setup
  • Strong forward throwing characteristic for better cd/m2 efficacy with fewer lumens
  • Designed to have low TI[%] value on most setups
  • Light spill reduced on the back side for increased negative contrast between street surface and vertical surfaces


  • Tunnel lighting
  • Wide area lighting applications that require narrow forward throwing distribution
