How to use
Install the Osram Dulux D 26 W lamp only in fixtures that accept G24d-3 base compact fluorescent lamps and are designed for T11 tubes. Ensure power to the luminaire is switched off before replacing the lamp. Insert the lamp into the socket and secure it according to the fixture design. Operate the lamp with the appropriate ballast or control gear specified by the luminaire manufacturer; do not connect the lamp directly to mains voltage unless the fixture is designed for it. Allow a short warm-up period after switching on for the lamp to reach its nominal light output and color temperature.
Usage recommendations
Use in indoor, dry environments and within the operating temperature range specified by the luminaire. For best color consistency and lifetime, avoid frequent on/off switching and ensure compatibility between the lamp and the fixture's ballast. Dispose of used fluorescent lamps according to local regulations for mercury-containing lamps.
