We get a lot of grey days here in West Cork. Especially in November. I might live in a beautiful place, but taking a photo a day outside is going to be challenging.
My home office has big windows which helps but on days like today some extra brightness is needed. The light fittings I have are GU10 spots which normally take energy hungry halogens. I tried compact fluorescents but they’re not good in this format. Fortunately LEDs are now getting cost effective and bright enough. I got these off eBay for £3 each. They’re 3watts and give about 400 lumens each. The warm white versions give a spectrum that’s quite pleasant without any warm-up time. Recommended!
