Hi Patti, I agree we were told several lights were on, I was just going by Adams belief of complete darkness to argue his point.
It's hard to be sure if lights were switched on and off while Jeremy was outside with the police or whether various police had inaccurate memories as some would explain it
So many different scenarios can be suggested, only Scorpio knows all the answers 
I wasn't there, I can't say which lights were on and which were not. Unless police took time at the scene to record precisely which lights were on and off, which they didn't, we are stuck with them trying to recollect later and it is not an issue that they would likely remember with precision. Remembering the light of a room they focused on all night is far more believable than recognizing everything in the house.
It is clear some were on and off, we will never know which ones were on and which ones off because the officers disagree with one another and it is not in issue that would stand out sufficiently in their memories later. Which they left on and which they didn't doesn't particularly matter anyway. It doesn't help add anything to knowledge about how the crimes went down since lights could have been turned on/off after the murders.
Aside from the fact the evidence proves they all died before the police arrived, the police were positioned too far away from the house to realistically see any movement in the windows regardless of whether lights were on and off. You can only see someone in a upper floor window if the person is directly in the window looking out and you are close enough to be able to see clearly inside. I can't even see inside my own windows from the end of my driveway I have to be pretty close. From my the end of the driveway at best I can see light cast from my computer or a television that is on but nothing more. I had to be rather close to the window to see my wife watching me take the garbage out. Because of the angle you can't see anything unless it is directly in the window. If you are in at the same elevation or higher then you can see deeper inside a window but from below you can't see that deep.
They didn't get close to the ground floor windows to look in either. Only after they decided to go in and commenced recon of the structure to figure out the best entry point did they approach the building and look in the ground floor windows hence seeing Nevill's body which they thought was June.
The only room that really matters at all is the master bedroom light because why would she close the lights to kill herself in the dark and yet be reading a Bible? But that still could be explained by the claim she wasn't reading it and just took it to leave near her. I don't know why someone would kill themselves in the dark but it is no out of the question to do so. Someone dying then removing the moderator, putting it away, going back to the same location where they died but positioning their body in a different manner than when they died, having a pool of blood for then placing the bible in the pool of blood are things that are out of the question in contrast. They are things that matter.
