Product information

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 clear cover highlights the LED design and produces a direct light beam. Physical dimensions (D x H): 35 x 38 mm.

Advantages

The LED bulb combines low power consumption with a luminous flux of 345 lm, giving energy-efficient replacement for small low-voltage halogen MR11 lamps. 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.

Suitable for

Accent and spot lighting in display cabinets
Small downlights and directional fixtures
Track lighting with MR11/GU4 sockets
Decorative luminaires where compact size is required

How to use

Ensure the fixture supports GU4 low-voltage bulbs and that the supply voltage matches the lamp’s requirements. Insert the bulb into the GU4 socket with gentle pressure until it is seated.
