As a rough guide on the requirements of CIBSE
Kitchen and living areas 200 – 300lux
Bathrooms, tolilets 150lux
Bedrooms 150lux + local task liighting
Corridors, hallways 100lux
Using 1M spacing gives 267lux average
Using 1.5M spacing gives 121lux average
Using 1.7M spacing gives 98 lux average
As a rough rule of thumb kitchens and living areas use 1M spacings. Bathrooms, toilets & bedrooms you can use 1.2M or possibly a bit more. And corridors, hallways etc. you can get away with 1.7M.
Obviously the above is a rough guide as other factors come in to play such as ceiling height, lamp type, wattage, kitchen cupboards etc but I find it a good rule of thumb when designing.
