It's worth noting that in the past, incandescent bulbs were rated in Watts ,we associated that with how bright they were. Led units are also rated in Watts but that only specifies to their electrical consumption, the light output is measured in lumens, not helpful if you're a first time user as there's really nothing to compare that measurement to, so initially I aimed for the lowest available leds and worked my way up from there. For example, I exchanged the MR16 halogen 60w units for 3W led ones and that was sufficient, the same in my kitchen, although I ideally should have gone to maybe 6W units. Pendant light fittings, I exchanged 100W incandescent bulbs initially for 3w led equivalent B22 units, you could exist with that, but you struggle to do anything accurately, 10W was better but most people would require 20W.
Also worth noting that ten years go there were two options for light colour, warm or cold. Warm light is closer to incandescent bulbs and is noticeably yellow only if you try cold light versions which are incredibly white in comparison, they now offer day light bulbs,which falls almost exactly in the middle and is the closest you can currently get to daytime sunlight, albeit from a different source. The intensity of which you choose. If you ask a retailer for their opinion on output, make sure you ask if they personally have used the exact model they are suggesting, as there are vast differences between different led manufacturers and led types. Or do as I do and order from China and try them yourself, they're so cheap from there if you guess wrong you haven't lost much other than the delivery time.
