We have a central ceiling light fitting with 5 x G9 lampholders.

I have had 40watt halogen G9s in but want to change to LED.

The first set (5watt)I got didn't like the dimmer so I bought a Trailing
Edge Dimmer. I decided they were not bright enough so I bought some more
that claim to have higher lumens. Now wife is saying the room looks dull.

Are Lumens to be believed? About to swop the 8 watt ones for a third set.

Any suggestions?

The Halogens claimed to be 460 Lumens.

The 8 watt LEDs claim 550 Lumens.

I am considering some that claim to be 720 lumens. Is it to be believed?

Any suggestions?

Colour temperature. Change from a 2700K to something a
bit higher up. There might be 3500K, 4500K, 9000K (bicycle light).
The 9000K would have a definite bluish tint to it.

Or, have wife tested :-)

I fondly remember picking a LED bulb at the store,
which said on the package "this is not a yellow bulb".
I took it home, projected light from previous bulb
and new bulb. And new bulb light was definitely yellow :-)
It became most obvious, when comparing the light outputs
at the same time.
