Spot bulb Philips MR16 GU5.3 7W (equiv. 50W), 621 lm, 2200K warm white, 36° beam, CRI 80, 15000 h

Philips MR16 GU5.3 spot bulb is a compact LED lamp designed for directional lighting in track fixtures, recessed housings and accent luminaires. With 7 W power and a light output of 621 lm, it replaces a 50 W halogen lamp while consuming significantly less energy. The bulb emits a warm 2200 K light with a 36° beam angle and CRI 80 for natural-looking colors, and is rated for up to 15,000 hours of operation. The lamp supports dimming and incorporates Philips WarmGlow technology, which shifts color toward warmer tones as brightness is reduced.

Advantages

The lamp delivers energy-efficient illumination with a compact MR16 form factor suitable for existing GU5.3 fixtures. Its WarmGlow behavior produces progressively warmer light when dimmed, giving greater control over ambience. A focused 36° beam enables precise accent lighting and minimizes spill, while the 2200 K color temperature provides a soft, warm appearance ideal for hospitality and residential settings. The long rated lifetime reduces maintenance frequency.

Suitable for

• Track lighting for galleries and retail displays
• Recessed spot fixtures in living rooms and kitchens
• Accent lighting to highlight artwork or architectural details
• Small directional luminaires in hotels, restaurants or homes

How to use

Ensure the fixture is compatible with a GU5.3 MR16 lamp and that the mains voltage and transformer (if present) are suitable for LED operation. Install the lamp by aligning the two pins with the socket and pressing gently until seated. Use a dimmer compatible with LED WarmGlow lamps to achieve progressive warming of the light when dimming. Avoid frequent on/off cycles when possible to maximize rated lifetime.

Usage recommendations

For best performance in directional and accent applications, pair the bulb with fixtures that offer proper heat dissipation and use compatible LED dimmers. Use the 36° beam to focus light on displays or features and position the lamp to minimize glare. Replace lamps in groups in multi-lamp fixtures to maintain uniform color and output over time.
