How would we know? You do not post pics of the lights or the room and no clue as to your style.I have a bedroom larger than yours with one of these lights in the center it lights the entire room so this is why we need more info.

These are the lights I am thinking of:

Right now, I am just focused on the diameter of these lights. I want to get opinions on whether this size would be OK spaced 8' apart (center to center) in a 20' x 20' room. Alternatively, I can go with similar lights that are 30" or 24" in diameter. Comments?

How large are the ones you're replacing? 36" seems like it would way too large for that type of fixture, and even moreso since you're going to have two of them. Why are there two? Even in a room that size that is an unusual arrangement. Also, you realize these aren't the best type of lights for illumination, they're more for appearance?

If you're able to reach the ceiling with a ladder, make circles from paper bags or construction paper of the various sizes and tape them to the ceiling with painter's tape to get a real idea of the different sizes. I'm guessing the smallest one will work, but you'll have to see what looks right to you.

The rule of thumb for a fixture to be the diameter of the L + W of the room is for a single central fixture. Here are two 36" fixtures 8 feet apart.

Well this ridiculous malfunctioning site won't post my picture in repeated attempts, but 36" is probably too big, particularly in that style.

The lights I'm replacing are 20" in diameter. I did an internet search on what is the recommended diameter of ceiling lights for different room sizes. This is the guideline I saw over and over:

* Take the room dimensions, in this case 20' x 20'

* Add up the two dimensions, i.e. 20+20 = 40

* Use 40" as the preferred light diameter.

That is why I looked at the 36" diameter lights mentioned above.

In terms of the amount of light that would be provided, I'm not too concerned since 21 bulbs in each light fixture can provide more than enough light and can be dimmed if too much.

I'm really just interested in how two 36" diameter lights would look in the room. I realize that "whether something looks good or not" is a personal preference - but I'm not a decorator and I think people who are decorators on this forum would be able to visualize it better than I can and know if a ceiling light is way too big or way too small etc. The 3 sizes that are available in the style are 36", 30" and 24". I'm sure they can all provide enough light so what would you pick from an appearance perspective alone. Thanks for any comments/suggestions.

IMO bedroom center lights need to be good enough lighting for cleaning the space I never use ours except for that we have great lamps which is what we use all the time .

I think they would look ridiculous. That formula is for one light, not 2.

Do a couple of cardboard cutouts.

I actually made full size 3-D cardboard cutout of the pendant I was using in my foyer and a 2-D cutout of my patio pendants to decide on height of fixture and hanging height.

What size would you use for two lights then - 24" or 30"? There are existing lights there now. So if I use one light only, it would have to be relocated so that it is balanced in the room. This would involve electrical work to relocate the light and also drywall work to patch up the existing two outlets on the ceiling. Two lights in the room look fine so I will stick to two. I would appreciate any further comments the members may have regarding the diameter of the two lights. The options are 36", 30" and 24". Thanks again - much appreciated!
