Standards on Series Products in Lighting System Clarified

The Ministry of Electronics and Information Technology (MeitY) has issued revised guidelines for the formation of product series under IS 16102 (Part 1): 2026 and IS 10322: 2026 standards for luminaires and lighting systems.

Key Changes

1. Definition of Product Family

·         A product family is defined based on a maximum configuration of components/sub-assemblies and how different models are derived from that configuration.

·         Models in a family should have common design, construction, parts, or assemblies essential for compliance.

2. Maximum Models Allowed in a Series

·         General limit: 10 models per series.

·         Fancy lights/Chandeliers (Item 22): Up to 50 models per series.

·         Items 21, 32–37 and 46 under CRO: Up to 20 models per series.

·         Normally, one representative sample is tested per series.

·         Testing must be conducted on the worst-case safety configuration.

Guidelines for Self-Ballasted LED Lamps (Item 21)

Models can be grouped into a series if they have:

·         Same rated input voltage.

·         Same LED driver/ballast rating.

·         Same mains PCB design and layout.

·         Same cap design.

·         Same IP rating.

·         Same battery chemistry (e.g., Li-ion and Ni-based batteries cannot be mixed).

·         Same charging and battery protection PCB design.

·         Different battery capacities may be included, provided the highest-capacity model is tested.

Common Criteria for Luminaire Series (IS 10322:2026)

Models in a series must generally have:

·         Same class of construction.

·         Same type of control gear (AC-powered, DC-powered, adapter-powered, PoE-powered, etc.).

·         Same rated input voltage/current.

·         Same enclosure material.

·         Same IP rating.

·         Same luminaire type (fixed, portable, track-mounted, etc.).

·         Same insulation class (SELV/PELV/Non-SELV).

·         Same energy-storage technology and battery chemistry.

·         Same nominal battery voltage.

·         Separate series for:

o    Products with/without replaceable batteries.

o    Products with/without rechargeable batteries.

Additional Series Formation Requirements

Separate series are required where there are differences in:

·         Presence of mains socket outlets.

·         Thermal management system (passive vs active cooling).

·         Ambient temperature rating.

·         Impulse withstand overvoltage category.

·         Adapter output voltage/current ratings.

Special Provisions for Fancy Lights/Chandeliers

·         Three samples representing highest, middle, and lowest ratings must be tested.

·         Additional checks are required for suspension/fixing arrangements based on different weights.

·         Only the electrical housing and safety-related electrical components are considered for model evaluation.

·         Since model numbers are often unavailable, pictorial documentation of each electrical fitting may be submitted instead of physical samples.

Key Takeaway

The revised MeitY guidelines standardize series formation under the updated IS 16102:2026 and IS 10322:2026 standards, while providing greater flexibility for product grouping, especially for fancy lights and chandeliers. The changes also introduce clearer criteria relating to battery technology, safety architecture, control gear, and testing requirements.
