How Do You Calculate The Number Of

7 watt ceiling spot lights needed to give good lighting in a room 17 feet by 12 feet.The room is used as a treatment room by a clinician. Am very appreciative of all help which may be given. Sincerely Brenda

That is exactly what my kitchen measures and I've got 8.

7 watts very low even for halogen ceiling lights, and forget led, more like 50 watts, thats what we have on a block of 4 in medium sized room

I agree with giveup. Eight 7watt LEDs should do you.

Very easy to add one or two more at a later date if not.

I use a rough guesstimate of 16 lumens per watt so if you know what incandescent wattage you presently use you have a ballpark figure for the lumens you need from your 7w LED lamps.
