How can I get the same render results of two scenes?

Hi! I have a problem guys. When I render a scene of a living room, the render is clear seeming it's a day. But if I render a scene of a bedroom, it looks something darker than the scene of the living room.
I wanted to copy the lights from the living room to the bedroom scene, but I couldn't find them (the scene didn't include lights, neither the bedroom one). Then, I tried to save as render settings of the living room in order to merge them into the bedroom, but the render shows me a lot of shadows even when it's clearer than the previous render.
If none of the scenes included lights, how is it possible the renders are too differents (one clearer than the other one) and how can I get the same render results of the living room in the bedroom (in order to seem it's day)?
I hope someone can help me because I'm new in render.
Thank you guys!

The "lights" are almost certainly emissive surfaces; material parameters that mean the models you have used for the bedroom scene are themselves emitting light. Although you can look at the bedroom's materials to get some clues aboutwhat parameters to use, it's not something that can really be directly copy-pasted from one scene to the other.
Would need to see the images or the scene tree, to even consider the reason why that's happening.
Yeah, lighting is one of the biggest parts of rendering. Once you get an idea, it's also pretty fun, And, as you're finding out, no two scenes are the same. Have you checked out any of the lighting tutorials for Daz on Youtube? There are lots of them. If you do, make sure that you are looking at more recent ones if you are rendering in Iray. The lighting rules for 3DL and Iray aren't exactly the same.
You may have more light coming in from the window in one scene vs the other. Are the two rooms in the same set? Having different wall surfaces also plays a part in how much light is reflected.
As mentioned, there are some rooms that come with mesh lights that can be adjusted in the surfaces tab. If the rooms really have no lights at all, though, then all the light you see would be coming in through the windows. Studio has a default IBL in the Iray render settings tab that creates a global light in the scene. If the living room has a big window and the bedroom only has a small one, that could be the reason the bedroom is darker.
As others have said, we need to know the products u are using. A lot of living rooms in the store have bigger windows, and/or windows on 2 or more sides. This alone can make the living room brighter, regardless of the presence of any emissive lights.
Thank you guys. The products I'm using are:

The Wohnen Living Room are clearer than the The Boys' Room, specifically the Day Messy Room which it's the one I'm using. The day messy room renders me something kind of blue like you can see in the promo pictures (the second one).
The specific question is: How can I get the same render result of the Living Room in the Boys Room? Please, explain me the more detailed you could because I'm still a beginner in Rendering and I don't understand some render terms. Thank you guys!
The living room has large windows on all four sides. The bedroom has small windows on two sides. It's darker in there because it would be in the real world, too.
Is this the real world? Or is it fantasy?
It looks like these sets use emissive lights. Here is something you can do. In the case of the boys room, you have controllers for a "Light" and a "Lamp". Make sure both are ON. Find and select them in your Scene tab or select them in the scene. Then go to the Surfaces tab. There may be a few surfaces with names like LED or Shade or whatever. One of them will have sliders in the Emissives section. One's called Luminance. Increase that one for the Light or the Lamp or both and your scene will get brighter.
OR! You can add lights. I don't know what you're trying to do with your scene, and that's pretty important when deciding your lighting. The best thing to do in your position is to go on Youtube and look at a bunch of Daz Studio Lighting videos. There are LOTS of them. Make sure they're not too old and that they're talking about IRAY lighting, since your scenes are all Iray.
The day version of the boys room will load without any of the lights on. It will only be lit by the light coming in through the windows. If you go to the render settings tab and click on environment, you can increase the intensity of the environment map to make more light come in through the window. That map is what is most likely creating your light by default. A second option you can try is tone mapping settings, which are also in the render settings tab. Turn down the exposure value and the room will look brighter. Also, the night version of the room will have the lights in the room on by default, and they can help light up the room as well. The type of lights in the room are most likely mesh lights and will make the render time longer.
I found the solution guys: I just loaded first the living room, I made it invisible and then I merged the boys bedroom and it worked. It doesn't work if you load the boys bedroom first and then merge the living room.
I share this solution in case someone has the same problem and can see how to figure out.
Thank you for your help guys! ;)
That has nothing to do with the room, and means that the render settings for the two rooms were not the same. Render settings can vary a lot, and some PAs make a lot of adjustments from the standard. You might want to learn about them.
