Hi, Below is the sketch for my dry kitchen. The total width is about 9ft, where left with about 5ft corridor after deducting the cabinets on both sides. Length is about 17ft. Planning to put 3 downlight spots as indicated by the red circle. Questions: 1) What's the size of the downlight needed? I'm planning to get the 5" light (around 900-950lm each). Is it sufficient? 2) What shall be the positioning distance? Shall I take 17ft/4 as the center to center distance to place the 3 downlights? Thanks

speaking from own experience. thats not enough. you need lights from the cabinets too. the work top is too dark due to shadow from cabinets. like this example: This post has been edited by ikeiyou: Mar 3 2023, 01:25 PM

QUOTE(lowyat101 @ Mar 3 2023, 02:08 PM) Then 3 pcs is sufficient (900-1200lm). Ensure you get quality downlights like Philips/Osram as their stated lumen output is true output. Have seen Philips 1200lm beat those China branded so claimed 1440lm when we use a lux meter to measure. (122lx vs 100lx). Also the Philips 1200lm only consume 12W whereas the China branded needs 18W.

For own house use, I only go for Philips with at least 30KHrs (3-Year Warranty) for downlights. No point to skimp for a few pcs as the installation cost is way higher. If you are concern with energy savings, look for downlights with efficacy of >95lm/W.

QUOTE(ikeiyou @ Mar 3 2023, 04:47 PM) I lazy to change bulbs regularly. Same here which is the reason why I changed all my older downlights to LED downlights. Typical LED bulbs lasts 8-10KHrs offering 1-Year warranty. Better quality lasts 15KHrs and better efficacy. Example as below: PHILIPS E27 LED Bulbs: 10Khrs 1055lm 11W 15KHrs 1055lm 9.5W To replace these E27 LED Bulbs downlight, we only need to replace it with 900lm LED downlight that is brighter and higher efficacy.
