Planning on fitting downlights in the dining room this weekend so called into Screwfix on the way home from work last night. I asked for 2.5mm twin core + earth but they only had 50m reels in stock. When i told the guy at the counter what it was for he assured me "6243YH 1.5mm twin core & earth" would be good enough. Is he correct or do I need 2.5mm?
Should it matter the down lighters I am fitting are mains GU10 led.
