## Long description

Osram STAR LED bulb in MR11 spotlight shape with a GU4 base emits warm white light at 2700 K and delivers 345 lm while consuming 4 W, providing brightness comparable to a 35 W incandescent lamp.

The warm white 2700 K colour temperature creates a familiar incandescent-like tone. Its compact MR11 form factor and GU4 cap make it compatible with many small fixtures. The clear lens produces a focused beam suitable for spot and accent lighting.
