Ok, but greenish light

The LED lamps should illuminate in a 4-spot chain a connecting room with a size of approximately 10 m² (2.5 x 4 m).

Basically, the LED lamps are ok. But for my taste they have two "disadvantages".
The warm white light described drift noticeably greenish spectrum.
The lamps are suitable only conditionally for my chosen purpose. It's just a connection room (passage) which connects the main rooms (living room, kitchen, bathroom, bedroom, ...). There is good enough, but leaves a "dim" impression.

Positives:
+ Price matches
+ Lamp immediately the complete light intensity

Neutral:
~ Not very bright

Negatives:
- Color spectrum drifts too greenish.
