OSRAM LED Star Classic A 40 4.9W 827 Frosted E27 is a classic A-shape LED bulb for general household lighting. It produces 470 lm for everyday illumination in living rooms, bedrooms and hallways. The 2700 K colour temperature provides warm-white light suited to domestic spaces. Its 4.9 W power rating keeps electrical demand lower than a traditional incandescent bulb with comparable output.
The standard E27 screw cap fits compatible lamps and ceiling luminaires. It runs from AC mains power and is intended for dry indoor locations. An IP20 rating means it is not designed for damp rooms or outdoor exposure. The frosted finish diffuses the light rather than leaving the LEDs visibly exposed. This bulb is non-dimmable, so it requires a standard on/off lighting circuit.
