AURAGLOW 6w LED GU10 Light Bulb, Warm White, 50w E&hellip by Auraglow
I've tried a variety of LED bulbs. These are the first that give me a reasonable light quality. I replaced 5 35W halogen GU10s with these bulbs.

If you already know how to wire a fused connection unit and are willing to learn more, then this will take you to a *reasonable* (albeit not comprehensive) understanding of how a domestic system works, and the requirements of BS7671.
