The L Mark

The L Mark of Laser Product Safety LLC (LPS) is recognized globally as one of laser, LED, UV and/or IR radiation safety. LPS clients display the L Mark with great pride to indicate they have taken the initiative to have their product tested and certified by LPS. If the product evaluation is successful manufacturers submit a sample once a year to LPS for re-testing to determine the manufacturer's continued compliance with global laser, LED, UV and/or IR radiation safety requirements. The L Mark on a product means that LPS has tested and evaluated representative samples of that product and determined that they meet the applicable radiation safety requirements. The product is re-tested once annually by LPS to ensure they continue to meet global radiation safety requirements. The L Mark may be only used on or in connection with products certified by LPS and under the terms of written agreement with LPS.  

A product certification from LPS is a valuable marketing tool. It means your product has successfully met stringent standards for radiation safety compliance. It will greatly assist you in promoting your product to the global marketplace. LPS does not “approve” products. Rather it evaluates laser, LED, UV and/or IR products, components, and systems for compliance to specific radiation requirements, and permits acceptable products to carry the L Mark, as long as they remain compliant with the standards. A manufacturer of a LPS-certified product must demonstrate compliance with the appropriate safety requirements. LPS conducts an annual re-test of the product to check ongoing compliance. If a product design is modified, a representative sample may need to be retested before the L mark can be attached to the new product. 

LPS certification does not guarantee the product will perform correctly or that it is safe under all conditions (such as product misuse). The L Mark does not carry any legal weight beyond that of any other company’s trademark. The L Mark is different from the CE Marking or the FCC Part 15 requirements, which are required by law. However, it may be difficult to sell laser, LED, UV and/or IR products without the L Mark. Distributors may be unwilling to carry a product without the L Mark certification, and the use of noncertified products may void insurance coverage. Local jurisdictional authorities, such as building, electrical and fire inspectors, may be unwilling to allow a product for installation unless it displays a third-party compliance mark such as the L Mark.  

If you have questions regarding the L Mark or submitting a laser, LED, UV and/or IR product to LPS for evaluation and eligibility to bear the L Mark, please contact any LPS office or visit the LPS website.
