The glow lamp I have is ~4x4 inch square panel, and it can get decently bright where I can feel some energy in my eyes and a difference in mood. That's what I've used for the past couple years. The thing I found with it is that it's almost like an orb, where there's energy glowing from it, but the rest of the area is still dark.

With the corn bulbs, it blasts energy and more light all over, which makes a much bigger difference in vibe. I can't comment on the lux difference (I'm actually getting a lux meter today so I can get a better number in comparison), but with more light all over the room, I can feel much more energy overall.

LED light panels are the other thing I think you mention, and I haven't tested with those. I picked corn bulbs to try first. Compared to the marketed mood lamps, the bigger panels would also light the whole room for a better vibe.

I don't think there are dimmable LED type higher power bulbs or panels. On or off for them. I'm planning to get more lights, and then maybe see if there's a way to create shades to put over them to change the color and amount depending on day.

For now, I'm keeping the lamps powered until ~6pm, and then back to the old light I had before to get ready for sleep.
