This pack of 10x LEDvance Performance Class LED MR16 spotlight light bulbs represents a stellar choice in the realm of energy-efficient lighting. They serve as a top-tier replacement for outdated 50W halogen spotlights, retaining the same level of brightness while dramatically reducing energy consumption.

Each light bulb emits a bright 621 lumens of cool white light, which, when combined with it's 36° beam angle and a high colour rendering of CRi >90 makes this spotlight bulb perfect for highlighting products in retail displays, in galleries and other display lighting.

Additionally, the dimmable feature provides you with enhanced control over your lighting, allowing you to tailor the light output to your specific preferences.

The light bulb's long 25,000 hour lifespan means that once installed, it will not need replacing again for years. The GU5.3 base also retrofits to existing light fixtures, so installing it is simply a case of swapping out the old light bulb for the new.

As this is a low voltage light bulb, it will need to be fitted with a compatible driver or transformer when installing on mains circuits. See the manufacturer's website for more information.

This LED MR16 spotlight lamp is fitted with a low voltage 12V GU5.3 2-pin (5.33mm apart) base.

This MR16 Spotlight is a newer product from Ledvance and supersedes their old MR16 Spotlight part codes: 4058075449428, AC32714, 4058075609272.

Please note that this light bulb will operate with most AC and DC 12V transformers. However, some 12V transformers may have a minimum required load which may not be met when installing low powered LEDs: these drivers may cause flickering or the LEDs not to function correctly. If this issue arises it may be necessary to source a suitable LED driver. Please refer to the manufacturers website for compatibility.

Please visit the manufacturer's website for up-to-date dimmer switch compatibility lists for this Ledvance LED MR16 Spotlight light bulb before purchase.
