The quality is excellent and it feels well-made. It arrived quickly and was well packaged, which was a nice bonus. It does exactly what it’s supposed to. Overall, it offers great value for money and I wouldn’t hesitate to recommend these bulbs to others. I would definitely buy these again. ### ⭐⭐⭐⭐ Worked once adjusted. *by K***N on 11 September 2025* At first it did not seem like these were compatible. I bought them for spares to replace the halogen reading lamps in our motorhome. The one I tried failed to light at the first attempt. However, I bent the contacts slightly to improve the connection and, hey presto! A good, bright, soft yellow light. The pack of 6 should last us years. ## Frequently Bought Together - 6 Pack MR11 GU4 12V 3W LED Bulb, Warm White 3000K, Equivalent to 30W 20W Halogen Spotlight Bulb, 300LM, GU4 Bi-Pin Base, 120°Beam Angle, Non-Dimmable, for Hallway, Living Room - Pack of 10 MR11 Retaining Spring Rings Clasp Clips Diameter 35MM LED Halogen Bulb Holders --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/540032057-caldarax-6-pack-mr11-gu4-12v-3w-led-bulb-warm](https://www.desertcart.com.ar/products/540032057-caldarax-6-pack-mr11-gu4-12v-3w-led-bulb-warm) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-21*
