Project On-Site Warranty
For lighting projects that are designed and specified by the Kosnic Lighting project team, provided the specification is not changed, a 1 year extended on-site warranty can be issued (excluding, DD and K2D products). This must be authorised by your Area Project Manager prior to the installation.

If a product fails within its on-site warranty period, the warranty holder must contact Kosnic Lighting in writing and will be required to complete a ‘Warranty Claim Form’.


The estimated cost for repairing and product replacement (excluding cost of travelling and accommodation) must be provided. If the proposed cost is considered fair and reasonable, Kosnic Lighting will authorise the work and reimburse costs accordingly.

If the estimated cost is deemed excessive, Kosnic Lighting will carry out the work with our own qualified engineers.
The on-site warranty will be void if the repairing and/or replacement of the faulty products starts prior to obtaining written authorisation from Kosnic Lighting.


An authorised representative from Kosnic Lighting must be allowed to have access to the faulty goods and installation site, before, during and after the work being carried out.

The following applies to both Product and On-Sites warranties:
The obligation to replace any product under the terms of the warranties set out above, shall only apply where it has been used for its intended or ordinary purpose and provided always that the following conditions have been met:


  • The warrant period commences on the date on invoice to the contractor/end user. If proof of invoice cannot be provided, then the manufacturing date determined from the batch code on the product will be used.
  • Kosnic Lighting products must be installed correctly, in accordance with the product information detailed on our packaging, instruction sheets, product data sheets and best industry practice.
  • All products repaired or replaced under the Kosnic Lighting warranty, will be warranted for the remainder of the original warranty terms and period.
  • Kosnic Lighting hold no responsibility for ‘mis-match’ of products when replacing discontinued product(s) under warranty.
  • Kosnic Lighting products under this warranty should not be operated over 5000 hours per year on average within the warranty period.
  • Kosnic Lighting Ltd cannot be held responsible for incompatibility of any lamp or luminaire with other manufacturers’ trans-formers, drivers, dimmers or control gear. A guide to compatibility where necessary is published on the Kosnic web site and is available on demand. Technical advice is always available upon request.
