Luxrite LR21405 MR16 LED Bulb 6.5W 3000K GU5.3 12V

Luxrite LR21405 MR16 LED Light Bulb – 6.5W, 3000K Soft White, 500 Lumens

The Luxrite LR21405 MR16 LED light bulb delivers bright, efficient 3000K soft white light while using only 6.5 watts of power. Designed as an energy-efficient replacement for a traditional 50-watt MR16 halogen bulb, this low-voltage LED produces 500 lumens with a focused 40° flood beam angle.

With its GU5.3 / GX5.3 bi-pin base and 12V input, the LR21405 is designed for compatible low-voltage MR16 fixtures. Its compact MR16 shape makes it an excellent choice for accent lighting, recessed lighting, track lighting, display lighting, landscape lighting, and other applications that use a 12-volt MR16 bi-pin lamp.

Warm, Comfortable 3000K Soft White Light

The Luxrite LR21405 provides 3000K soft white illumination, offering a comfortable balance between warm and neutral light. With a light output of 500 lumens and an 80 CRI, it provides clear, consistent illumination for residential, commercial, retail, hospitality, and accent-lighting applications.

Dimmable MR16 LED for Adjustable Lighting

This dimmable MR16 LED bulb is compatible with appropriate TRIAC dimming systems, allowing you to adjust light levels to suit the space and application. Whether you need bright task or display lighting or softer accent illumination, the LR21405 provides flexible light output when used with a compatible LED dimmer and transformer.

50-Watt Halogen Replacement Using Only 6.5 Watts

Upgrade compatible 50-watt MR16 halogen lamps to LED with the Luxrite LR21405. The bulb uses only 6.5 watts while producing 500 lumens of light, helping reduce energy consumption without sacrificing useful light output.

With a rated life of up to 25,000 hours, this LED MR16 also helps reduce the need for frequent bulb replacement compared with conventional halogen lighting.

40° Flood Beam for Focused Illumination

A 40-degree flood beam angle provides a controlled spread of light that works well for accent, display, directional, and general-purpose MR16 lighting applications. The focused beam makes the LR21405 particularly useful where you want to illuminate a specific area without the very wide light distribution of a standard household bulb.

Suitable for Enclosed Fixtures and Damp Locations

The Luxrite LR21405 is enclosed-fixture rated and damp-location rated, providing additional flexibility when selecting a compatible fixture. It is also ETL listed and backed by a 3-year manufacturer warranty.
