Glare-Free LED Tunnel Lighting Solution (30W–400W)

Specially designed for roadway and railway tunnel applications, this glare-free tunnel light range (30W to 400W) delivers uniform illumination, low glare, and high visual comfort, meeting the stringent technical requirements of national highway and rail infrastructure projects.

The luminaire is designed according to tunnel lighting zone guidelines (threshold, transition, and interior zones) as per international standards such as CIE 88:2004, IRC:SP 90, and other relevant BIS specifications. It ensures enhanced visibility, safety, and comfort for drivers and maintenance personnel.

Applications

• Road tunnels (NHAI / MoRTH Projects)

• Railway tunnels (RVNL, IRCON, DMRC, etc.)

• Metro rail underpasses and pedestrian tunnels

• Mining and underground passageways

• Flyover underpasses

• Service tunnels

​
