yes ..for your case yes ...

my case is to find higher lumem which is over 2100k with less than 30W for to cover widen area outside my house ...
initially thinking your 24W 7000k will covered widen ...but its not ..caused lumem still less than my current Philip...

I not sure what age are you. But have you notice that, older people have problem seeing in dark or at night ?

They often complain that the place is too dark. While the young said it's fine?

That is the problem when you constantly expose to light too bright and glare.

Especially now 6500k is not enough for people. That is some alarming problem coming.

What happen if people chasing till 7500k or 8000k ?

3500k or yellow light is not dimly lit. Yellow light can be very bright if the lumens is high. Again don't confuse between bright and color or Lumens and kelvin.

Have you use before downlight bulb CFL which is 3500k 1600L ? If you use before, you know how bright that yellow CFL bulb. 

Do you know light color have wavelenght? Why street light or your car head light is yellow? Why all the car brand don't put a 7000k head light?

so conclusion means LUMENS is very important for light bulb.... correct me if I am wrong...
