Luminaire Classification System (LCS) and Environmental Impact

Outdoor lighting systems are increasingly scrutinized for their environmental impact, particularly in terms of light pollution, light trespass, and glare. The IES BUG (Backlight-Uplight-Glare) rating system has replaced the older “Cutoff” LCS to address these concerns effectively.

Key Elements of the IES BUG Rating System:

• Backlight: Measures light emitted opposite to the main aiming angle. Classified into high (60 – 80 degrees), medium (30 – 60 degrees), and low (0 – 30 degrees).
• Uplight: Assesses light emitted at or above the horizontal plane. Categorized as high (100 – 180 degrees) and low (90 – 100 degrees).
• Glare: Evaluates forward and backward light intensity, categorized similarly to backlight.

Detailed Zonal Classification:

• Forward Light (0° – 90° vertical, 90° – 270° horizontal):

  • Includes segments: low (0° – 30° vertical), mid (30° – 60° vertical), high (60° – 80° vertical), and very high (80° – 90° vertical).

• Backlight (0° – 90° vertical, 90° – 270° horizontal):

  • Segmented into: low (0° – 30° vertical), mid (30° – 60° vertical), high (60° – 80° vertical), and very high (80° – 90° vertical).

• Uplight (90° – 180° vertical, 0° – 360° horizontal):

  • Divided into: low (90° – 100° vertical), and high (100° – 180° vertical).
