Philips MR16 LED Bulb 5.8W GU5.3 12V Dimmable Warm White

The MASTER LEDspot range from Philips provides a low-energy, long-lasting LED MR16 spotlight option designed to replace outgoing halogen spots. This version uses a low voltage MR16 base and retrofits directly to existing fixtures, delivering the same light quality and brightness as a traditional 35W halogen while consuming a fraction of the power. With a significantly longer stated lifetime and reduced heat, UV, and IR output, these LEDs are well suited to heat-sensitive applications and materials preservation, while still fitting modern lighting needs with compatibility across common 12V transformer setups.

Technical specifications

• Power consumption: 5.5W (5.8W variant mentioned)
• Light output comparable to 35W halogen
• Lifetime: up to 25,000 hours
• Base: 12V GU5.3 2-pin
• Beam angle: 36 degrees
• Direct retrofit for MR16 fixtures

Note that some 12V transformers require a minimum load; if the LED load is too low, flickering or non-function may occur and an LED driver may be needed to ensure compatibility.
