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?
