1. Introdución e finalview
Thank you for choosing Sunco T8 LED 4-Foot Tube Light Bulbs. These 18W, 5000K Daylight, Single Ended Power (Type B) bulbs are designed as a direct replacement for traditional fluorescent tubes, offering superior brightness and energy efficiency. Each bulb provides 2200 lumens of consistent, flicker-free illumination, making them ideal for various indoor applications such as garages, workshops, and commercial spaces.
These LED tubes are engineered for a ballast bypass installation, which eliminates the need for an existing ballast, thereby reducing maintenance and extending the fixture's lifespan. Please read this manual thoroughly before installation and operation to ensure safe and proper use.
2. Información de seguridade
WARNING: Prior to installing Type B LED tubes, all existing ballasts must be removed, and the fixture rewired accordingly. Failure to do so may damage the lighting tube and create a serious fire hazard. Installation should only be performed by a qualified electrician or a knowledgeable individual with proper safety precautions.
- Desconecte sempre a alimentación no disyuntor antes de comezar calquera traballo eléctrico.
- Asegúrese de que o dispositivo estea correctamente conectado a terra.
- Do not use these LED tubes with a dimmer switch unless explicitly stated as dimmable. These are non-dimmable bulbs.
- Inspect the tubes for any damage before installation. Do not install damaged tubes.
- Usar equipos de protección individual (EPI) axeitados, como lentes e luvas de seguridade.
