QI Classic 5W LED R7s J78

• The Eurolux QI Classic 5W LED R7s J78 is a state-of-the-art lamp engineered to be the definitive, energy-efficient replacement for traditional 78mm linear halogen bulbs.
• This high-performance LED directly solves the critical problems associated with linear halogens: exorbitant energy consumption, dangerously high heat output, and a frustratingly short operational life.
• Its most significant differentiating factor is its ability to deliver a powerful, wide-spread light from a compact, cool-running package.
• By combining a certified high efficacy of 90 lumens per watt with an exceptionally broad 250-degree beam angle, the Eurolux QI Classic 5W LED R7s J78 transforms floodlights and uplighters from inefficient energy drains into modern, sustainable lighting fixtures.
• Available in both a cozy 3000K Warm White and a crisp 4000K Cool White, it is the ultimate plug-and-play solution for dramatically reducing costs and maintenance in both residential and commercial applications.

Features

• Exceptional Energy Efficiency: Consumes a minuscule 4.9W/5W of power while producing a bright 441 lumens, offering a direct replacement for 40W-50W linear halogens with up to 90% energy savings.
• Certified High Efficacy: Boasts a certified performance of 90 lumens per watt, guaranteeing maximum brightness for every unit of electricity consumed.
• Extremely Wide 250° Beam Angle: Provides a vast, almost omnidirectional spread of light, perfect for wall-washing, general floodlighting, and creating even, shadow-free illumination.
• Extremely Long Lifespan: Engineered for a durable 15,000-hour operational life, providing years of consistent, maintenance-free performance and virtually eliminating the need for replacements.
• Direct Retrofit Design: Features the standard R7s double-ended base and a 78mm length for a simple, push-and-fit replacement in any compatible fixture.
• Choice of Two Colour Temperatures:
  • 3000K Warm White for a relaxing and inviting atmosphere.
  • 4000K Cool White for a clear, neutral, and modern light.
• High Colour Accuracy: A Colour Rendering Index (CRI) of over 80 ensures that colours under its light appear natural, vibrant, and true-to-life.
• Cool-Running Operation: Generates significantly less heat than halogen bulbs, enhancing safety and reducing heat load in indoor spaces.
• Instant-On Brightness: Reaches 100% brightness immediately upon being switched on, with no flicker or warm-up delay.
• Durable Construction: Built with high-quality components for reliable, long-term performance in a variety of environments.

Benefits

• Massively Reduce Your Energy Bills: By replacing a single 50W halogen floodlight bulb with the QI Classic 5W LED R7s J78, you cut that fixture's energy consumption by up to 90%, leading to substantial and immediate savings on your electricity costs.
• Enjoy Years of Maintenance-Free Operation: The long 15,000-hour lifespan means you can install this bulb in hard-to-reach floodlights or uplighters and forget about it for years, eliminating the recurring cost and hassle of frequent replacements.
• Vastly Improved Safety: The cool-running LED technology dramatically reduces the extreme heat produced by halogen bulbs, lowering the risk of fire and making fixtures safer to be around, especially in areas with foot traffic.
• Superior and Broader Illumination: The exceptionally wide 250° beam provides a far more even and useful wash of light compared to the often-uneven output of a linear halogen, effectively illuminating entire walls, patios, and workspaces without dark spots.
• The Easiest Lighting Upgrade: The standard R7s 78mm design allows for a direct, one-for-one replacement. Simply remove your old, hot halogen tube and pop in this modern, efficient LED lamp.
• Customize Your Environment's Feel: The choice between the cozy ambiance of Warm White and the clean clarity of Cool White allows you to perfectly tailor the lighting to suit the function and style of your space.
• See Colours as They Were Intended: The high CRI ensures that your building's facade, garden features, or interior decor will be rendered in their true, natural colours, enhancing the overall aesthetic of your property.

Tips

To ensure you get the best performance and longevity from your Eurolux QI Classic 5W LED R7s J78, please follow these expert recommendations:

• CRITICAL - Check Fixture Dimensions: This is the most important step. While this LED lamp is a 78mm R7s replacement, its diameter (approx. 25-27mm) is significantly thicker than a thin glass halogen tube. Before purchasing, you must measure the internal space of your light fixture to ensure this larger bulb will fit without touching the reflector or glass cover.
• Use on Standard Switches: This bulb is non-dimmable. To ensure its long life and prevent damage to the internal driver, it must be used on a standard on/off light switch. Do not install it on a circuit controlled by a dimmer switch.
• For Outdoor Use in Sealed Fixtures Only: To use this bulb outdoors, it must be installed in a fixture with a suitable IP rating (e.g., IP44 or higher) that fully protects it from direct exposure to rain, moisture, and dust.
• Choose the Right Colour: Use 3000K Warm White for creating a cozy, relaxing ambiance in living areas or patios. Use 4000K Cool White for security lighting, workshops, and any area where clarity and visibility are the priority.
• Safety First: Linear halogen bulbs run extremely hot. Ensure the old bulb is completely cool before attempting to remove it. Always turn off the power at the circuit breaker before installation.
