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.
