Part of the reason that LED bulb "isn't bright enough" for you, is because you're used to seeing everything in a much brighter light. Once you change the rest of those lights to the LED bulbs, give it about a week, and then put the Halo's back in. You'll immediately notice that the light output from the Halo's is TOO bright, and you won't be able to focus properly.

The fact that your eyes are adaptable is what pushes the movement for lower-powered bulbs.. in a closed space, given time to adjust, you can see just as clearly with a 40 watt bulb as you can with a 60 watt bulb. The fact that people don't notice immediately what will happen in a week or so, is what stops us all from getting lower-powered bulbs.

If you don't trust the watt rating of the LED bulbs, get a kill-a-watt and put the bulb in a lamp that you plug into a wall somewhere.

PS - I know you've been told for years not to put bulbs in a lamp that wasn't rated for them, but that only applies to bulbs that are rated HIGHER than your lamp is. Less wattage isn't a problem at all.
