Industrial Road Lighting Requirements
IS 1944 Category M2/M3 applies to most industrial area roads (arterial and collector roads within industrial estates). Typical specifications: maintained average illuminance 15–20 lux for main industrial roads. 20–30 lux at factory gates, security check-posts, and loading dock approaches. 10–15 lux for internal service roads and parking. IS 3646 (interior) applies to factory yards and loading bays (not covered roads use indoor standards). Higher uniformity ratio (Uo ≥ 0.40) is recommended for industrial roads where heavy vehicle manoeuvring is frequent - poor uniformity creates depth perception problems for HCV drivers.
Pole and Luminaire Specifications for Industrial Areas
Pole height: 8–9m for main industrial roads (wider carriageways, 8–10m). 6–7m for internal roads. 10–12m for large open yards (use flood lights). Material: hot-dip galvanised MS minimum - industrial areas often have corrosive atmospheres (chemical, food processing, textile zones). Stainless steel hardware for food processing or chemical zones. Luminaire IP65 minimum; IP66 for chemical and food zones where hosing down of roads occurs. IK09 or IK10 recommended - heavy vehicle vibration and occasional mechanical contact. Surge protection: 10kV/5kA for industrial areas - large motor-driven machinery on the same electrical grid creates transient surges that damage lighting drivers.
MIDC Maharashtra - Specific Guide
Maharashtra Industrial Development Corporation (MIDC) manages 290+ industrial areas across Maharashtra. MIDC maintains roads, drainage, and common infrastructure within its estates. Street lighting in MIDC areas is either MIDC-maintained (for common roads) or unit-maintained (for private factory frontages and internal access). For MIDC common road lighting upgrades: projects go through MIDC's Annual Plan - vendors must be on MIDC's approved vendor list. For private factory roads within MIDC: the factory can purchase directly. Xera Tech supplies to multiple MIDC areas including Satpur MIDC, Ambad MIDC, Sinnar MIDC (Nashik), Chakan MIDC, Talegaon MIDC (Pune), and others. The company is based at Satpur MIDC, Nashik - MIDC procurement is a core business.
Energy Management for Industrial Lighting
Industrial areas have two distinct lighting needs: perimeter and road lighting (all night, 10–12 hours), and internal yard lighting during operational hours (typically 6am–10pm for day shift, all night for 3-shift operations). Smart lighting systems with SCADA control allow: automatic off during non-operational periods, dimming during low-activity periods (weekends, holidays), fault monitoring (an unlit security light is a safety and liability issue), and energy metering per zone for internal energy accounting. ROI for smart industrial lighting: typically 18–30 months, then pure savings for 12+ years of LED life. Xera Tech's technical team designs industrial lighting layouts with photometric reports on request.
