Introduction
Tungsten filament lamps may be traditional lighting products, but manufacturers as well as importers must still pay attention to applicable Indian product compliance requirements. ISI Mark Certification for Tungsten Filament Lamps under IS 418:2004 helps businesses determine whether their products meet the prescribed Indian Standard. From understanding product applicability to completing testing, factory inspection, as well as documentation, businesses must follow the correct BIS certification process before entering the regulated Indian market.
What is BIS ISI certification for Tungsten Filament Lamps?
BIS ISI certification for Tungsten Filament Lamps is a mandatory compliance requirement that is required to make sure that these products follow the prescribed quality and safety standards as per IS 418: 2004, and are thereby reliable to be sold as well as used in the long run. The ISI mark certification is granted by the Bureau of Indian Standards (BIS), which also governs other BIS certification types for notified product categories such as IT & electronics and machinery & electrical components.
Is ISI Mark Certification Mandatory for Tungsten Filament Lamps?
Yes, the applicable BIS ISI Mark certification requirement is mandatory for tungsten filament general-service electric lamps that have been covered by the compulsory product category. For manufacturers whose products fall within the notified category, understanding the different BIS certification schemes and obtaining the appropriate BIS license before regulated products are manufactured or marketed in India is an essential compliance requirement.
Importers and traders should understand one essential point – The manufacturer obtains the product certification. An importer cannot simply register an already manufactured lamp under its own name. Instead, it should verify that the actual manufacturer holds a valid licence covering the product that is being sourced.
Understanding IS 418:2004 Before Applying
IS 418:2004 is the Indian Standard titled Tungsten Filament Lamps for Domestic and Similar General Lighting Purposes. It establishes technical requirements that are actually relevant to the specified lamps and forms the basis for their BIS product certification.
Before beginning ISI mark registration, manufacturers should identify the exact product specifications and check whether the proposed lamp falls within the standard's scope. The IS 418 identifies several characteristics that are used to describe the licensed product:
- Rated voltage and wattage
- Bulb designation and shape
- Type of lamp cap
- Finish of the bulb
- Luminous flux
These details are important because a BIS licence is granted for a defined product scope, not automatically for every product that is being manufactured by a company.
Which tungsten filament lamps are covered?
The following examples of lamp characteristics within the standard's scope are covered as per this IS:
| Parameter | Examples or requirements |
| Rated wattage | 15 W, 25 W, 40 W, 60 W, 100 W, 150 W and 200 W, as described in the referenced product information |
| Rated voltage | 110 V, 230 V, 240 V and 250 V, subject to the standard's requirements |
| Bulb shapes | A, K, M or PS |
| Bulb finishes | Clear, frosted, equivalently coated or white |
| Lamp caps | B22d or E27 |
Practical tip: If you are unsure whether you require the mandatory ISI mark registration, check your product eligibility for BIS ISI Mark certification today.
What Tests Are Conducted on Tungsten Filament Lamps?
Testing establishes whether the lamp satisfies the relevant performance, dimensional, and safety requirements. The exact test programme must be determined from IS 418:2004. However, here are several important test areas for the notified products as per the specified IS:
| Test area | What it helps establish |
| Marking | Whether the prescribed product information is correctly displayed |
| Lamp dimensions | Whether physical dimensions meet the specified requirements |
| Wattage | Whether electrical power characteristics comply with the standard |
| Initial luminous flux | Whether the lamp provides the required initial light output |
| Insulation resistance | Whether the relevant electrical insulation requirements are met |
| Protection against accidental contact | Whether applicable safeguards against contact with live parts are satisfied |
| Interchangeability | Whether the lamp's relevant fitting characteristics meet the prescribed requirements |
Key Eligibility Compliance for ISI Mark Certification for Tungsten Filament Lamps
To obtain an ISI Mark certificate for tungsten filament lamps, manufacturers must meet the applicable BIS requirements under IS 418:2004. Before applying, businesses should verify the following eligibility and compliance conditions:
- Eligible manufacturer: The applicant must be the actual manufacturer with an identifiable manufacturing facility.
- Applicable product standard: The lamps must fall within the scope of IS 418:2004.
- Manufacturing infrastructure: The factory must have the machinery and production facilities that are needed to manufacture compliant lamps.

- Product conformity: The lamps must satisfy the prescribed requirements for relevant characteristics, including dimensions, wattage, luminous flux and electrical safety.
- ISI Mark vs ISO Mark: The ISI mark must not be confused with the ISO certification, as both serve different purposes and intended markets. Understanding the difference between ISI and ISO marks is thereby an important consideration for businesses planning compliant operations.
- Required documentation: The manufacturer must submit the prescribed application, factory details, technical specifications, and supporting documents to the BIS officials.
- Factory inspection and testing: The applicant must cooperate with the required BIS factory assessment and product testing.
- Foreign manufacturer requirements: Overseas applicants must follow the applicable Foreign Manufacturers Certification Scheme (FMCS), including Authorized Indian Representative requirements where applicable.
- Post-certification compliance: The licence holder must follow ISI and BIS CML marking rules, maintain production quality and meet applicable inspection, testing and renewal requirements.

What Happens After the BIS Licence is Granted?
Businesses must understand that obtaining the BIS licence is the beginning of ongoing compliance, not the end of the process. Be it obtaining a BIS certificate for paver blocks or a BIS licence for household electrical goods such as Tungsten Filament Lamps, ensuring mandatory compliance even post-certification grant is important.
Manufacturers must continue to produce the approved lamps in accordance with the applicable requirements and conditions of the licence.
Important post-certification responsibilities
- Correct marking: Apply the ISI Mark and licence details as prescribed.
- Production control: Maintain consistent manufacturing processes and product quality.
- Inspection and testing: Follow the applicable Scheme of Inspection and Testing.
- Records: Maintain production, quality-control and test records.
- Surveillance: Cooperate with applicable factory and market surveillance activities.
- Renewal: Monitor the licence's validity and submit renewal applications and fees within the applicable timelines.
- Scope control: Obtain the necessary approval before making changes that require an amendment to the licence.
- BIS Care App: Use the BIS Care Application to keep a record of your certifications, track validity periods, verify licence credibility and more, to ensure smooth BIS compliance always.
BIS may conduct surveillance as well as product sample testing during the licence's operation. Failure to maintain compliance can surely result in regulatory action, including suspension or cancellation of the licence.
Therefore, before changing a lamp's design, wattage, cap type, or manufacturing arrangement, the licence holder should check whether the change affects its approved scope. Contact a professional BIS ISI certificate consultant in India, and ensure hassle-free BIS certification for your products.
