Mains Voltage LED downlights, low voltage?

[BennyC]

Is anybody able to identify the recommended Lux levels/amount per room?

Living room
Kitchen
Bedroom
Bathroom

As I've been using the Halers utility on their site to plan how many lights I need per room but I'm unsure on the amount of 'Lux' I need to achieve.

I read that a living room should be around 150 but then also read it should be 300?

Thanks
