Osram LED Star Classic A 40 4,9W lampadina bianco caldo E27 opaca A60

The Osram STAR CLASSIC A 40 LED bulb delivers the familiar warm-white glow of a 40 W incandescent lamp while consuming only 4.9 W. Its frosted A60 envelope produces soft, uniform light without visible hotspots, making it a direct retrofit for household fixtures with an E27 socket. With a rated lifetime of 15,000 hours and 100,000 switching cycles, it reduces the frequency of bulb changes in hard-to-reach luminaires.

Highlights

• 470 lm luminous flux with 2700 K warm-white colour temperature
• Energy efficiency class F on the EU energy label
• Frosted A60 bulb shape for glare-free, even light distribution
• Non-dimmable design for simple, reliable operation

In daily use

This lamp reaches full brightness in under half a second, so there is no waiting for light when you flip the switch. The 300° beam angle spreads light broadly across the room, and the high colour rendering index of ≥80 Ra keeps colours looking natural. It operates on standard 220–240 V mains at 50/60 Hz and contains no mercury.
