Before investing in any light therapy device, verify the certifications available. Check the manufacturer's official websites for documents related to FDA registration numbers. If certification information is vague or non-clarifying, contact companies directly. Reputable brands will provide transparent verification information voluntarily.

Give preference to products with FDA clearance, as this is the essential validation, since it indicates that the product demonstrates clinical proof of efficacy for the diagnosis of seasonal affective disorder. The FDA clearance process mandates rigorous safety testing for possible eye damage and electrical safety concerns as well.

Certification for UV filtration avoids retinal injuries over extended use. Filtration of these wavelengths can be accomplished properly by blocking harmful ultraviolet wavelengths while allowing therapeutic visible light to pass through. Ensure that independent laboratory tests substantiate the manufacturer's declaration and specifically claims to be UV-free.

Certification for electrical safety helps avert fires and malfunctions. Look for UL ETL or CE markings on devices to verify they comply with internationally recognized standards. These marks also help prevent electrical shock and ensure reliable operation during daily use.

Avoid uncertified products regardless of attractive pricing. These often lack proper safety features and therapeutic effectiveness. Investing in validated equipment ensures both safety and successful seasonal mood improvement.
