Cool White 4000K – Crisp and Modern Lighting

The 4000K cool white output is one of the defining features of this UniBulb LED GU10. Unlike warmer tones, which produce a softer, yellowish glow, cool white strikes a balance between clarity and comfort.

This makes it a great choice for areas where visibility and focus are important. Whether you’re preparing food in the kitchen, working at a desk, or highlighting products in a retail space, the cool white light ensures everything looks clear and professional.

Popular uses for cool white lighting include:

• Kitchens and food preparation areas

• Bathrooms where clean brightness is needed

• Home offices to support focus and productivity

• Retail displays for professional presentation

• Studios and workshops requiring task clarity

Flexible Dimmable Functionality

One of the standout benefits of this bulb is its dimmable feature. Unlike standard LEDs that are fixed at one brightness, this GU10 allows you to fine-tune the level of illumination to suit your needs.

• Lower the brightness for evening relaxation or mood lighting.

• Increase brightness for tasks requiring sharper visibility.

• Adapt lighting for different activities in the same space.

Please note: Always check that your existing dimmer switch is LED-compatible to ensure smooth operation without flickering.

Long-Lasting Reliability – 25,000 Hours

With a 25,000-hour lifespan, this UniBulb LED GU10 outperforms traditional halogen bulbs by a wide margin. For most households, that equates to years of dependable use before a replacement is needed.

• In homes: Reduces the hassle of frequent bulb changes.

• In businesses: Cuts down on maintenance and replacement costs.

• In high-use spaces: Maintains steady output even with frequent on/off cycles.

Built for durability, the bulb is designed to keep working reliably without the rapid burnout associated with older halogen models.

Energy Rating E – Meets Modern Standards

This GU10 LED carries an Energy Rating of E under the latest EU/UK energy scale. The grading system has been updated in recent years, meaning ratings are now stricter. Despite this, the bulb still provides significantly better efficiency compared to halogen bulbs, which consume far more power.

At just 3.6W consumption, it produces the same useful light output as a traditional halogen spotlight that typically uses 35W or more. This ensures you enjoy the right brightness while avoiding unnecessary electricity usage.

Precise 36° Beam Angle

The 36-degree beam angle makes this GU10 bulb highly versatile. It produces a focused cone of light, perfect for spotlighting specific areas or objects without wasting illumination where it isn’t needed.

This makes it ideal for:

• Accent Lighting: Highlighting artwork, furniture, or displays

• Task Lighting: Focused illumination for kitchens or desks

• General Lighting: In groups, multiple bulbs provide wide coverage

• Retail or Hospitality: Directs light exactly where it’s most effective
