I have been working on a large build on a hard survival world for quite some time. So far I have managed to build it up quite a bit and have installed carpet within every room and redstone lamps that go on automatically at night in most of the rooms via solar panel.
Now what I am currently planning to do is remove all of the torches in order to rely solely on the redstone lamps for light, but I knew that I would need to carpet the floors in order to stop daytime spawn ins. However I wish to know whether or not hostile mobs could still spawn on single blocks that would not be covered (Such as the kitchen counter made out of 4 blocks of nether quarts).
Unfortunately I cannot seem to find anything on the wiki or Youtube that can tell me exactly how a hostile mob would spawn under the conditions I have made. Also, do I have to have the entire floor covered in my house to stop spawn ins? Or can mobs only spawn if there is enough available space?
Each mob has distinct spawning requirements, but the main factors are:
Area: Spiders require a 3x3x2 space, so if you only have single spaces as open available areas, you will avoid them from spawning. However Skellys and Zombies only need a 1x1x2 block of space.
Light Level: in the overworld most of the mobs require a light level beolw 7 for soawning, light from a redstone lamp is considered 15 at the source and drops by a value of 1 for every block away from the redstone lamp, so, if you are within 7 blocks you are fine.
Spawning Block: Most overworld mobs require a solid block under them to spawn, and there are some conflicting things I have read about mobs spawning "on" or "in" carpets, to avoid this debate I use 1/2 slabs or glass. You might want to put slabs or glass under your carpet to be safe?
You should do some more research or testing for point 3.
Mobs don't spawn on carpet, so to speak, but rather 'in' it, and thus your house is not safe during the day if the light level is below 8. Also 'top slabs' can spawn mobs. As a rule of thumb, if the slab allows you to place a torch 'on' it, it can and will spawn mobs if the light level is below 8. Slabs that are placed on the bottom half of a block can NOT spawn mobs, nor can mobs spawn on water or glass. They can't spawn on glowstone or lily-pads. Mobs can't spawn where a 'torch' is on the floor, but can spawn on other light producing things such as jack-o-lanterns. Most mobs have different height requirements, but most require 2 blocks of air to spawn, except iron golems which can spawn anywhere within the iron golem spawning box, provided there are 2 solid blocks below thier feet and no solid blocks 3 blocks above, which means that iron golems can spawn completely encased within transparent blocks such as slabs, glass, glowstone, and redstone blocks, ect.
If you wish to use a daylight lighting system i strongly suggest using hidden lighting, such as glowstone under your carpets if you insist on using carpets, or a half-slab floor.

Thanks for the information. After I had made this thread, I went and played Minecraft in order to test whether or not having no torches would work, but as stated above, they must have spawned within the carpet as some mobs managed to get inside. So I guess the torches will need to remain for now until I decide how I want to do this. perhaps I will install some automatic redstone lamps in the floor so that they are on in the day, but shut off at night, leaving the main lights in the ceiling as the main light source.
As a side note, one of the more interesting effects of this little experiment was that even during the day, and after the torches were removed, the house became relatively dark inside and created an atmosphere that was kinda creepy and unsettling. The house itself is made of stone, similar to that of the stronghold, and is about 30 blocks long, so it was kinda uncomfortable when you stand at one end and look into the shadowy area across. lol
Again since you have a 'carpeted' floor, you could easily hide some glowstone in the floor, and cover it with carpet, as you can place carpet on top of glowstone, its much better then torches imho.
Depending on how high the ceilings are in your builds the RS lamps might lose some of their effectiveness in preventing spawns. Like Cire360 mentioned, hide some glowstone under the carpet. Wait for night and look for dark areas that the RS lamps aren't adequately illuminating. If aesthetics are important to you, count out the dimensions of the room and place the glowstone evenly throughout the room to give it a uniform look.
The RS lamps at this point become merely cosmetic, but at least you won't have any hostile mobs.
I am having the same problem in a pyramid jungle-like temple I created (from looking at another's build). There are only 2 torches at the stairs, then nothing until the end of the maze. The bottom layer is approximately 35x35, torch at far corner of one side yet no monsters spawn inside. The pathways vary from 1 block wide to 3 in some areas. It is also nighttime outside.
If monsters cannot spawn, I will probably just redo the maze and make a trap deal like the generated temples do with arrows

Well this is actually the opposite of the OP's intentions as he was looking to make sure mobs do 'NOT' spawn within the area, and you are looking to have mobs spawn in the area, in which case the rules are different.
If your looking to increase mob spawn rates, then you need to not only look at the number of spawn spaces within the area, but also the number of air blocks. All spawns begin by choosing random air blocks, and then doing some funky random movements in random locations to choose a spawn location providing it meets the spawn criteria (ie enough height to spawn the mob, light level, ect.), so look at 'decreasing' mob spawn rates in other areas, and increasing spawn rates within your maze by providing more air blocks. Also remember that mobs can NOT spawn within 24 blocks of a player in a sphere. Without seeing the area in question is a bit difficult for me to offer suggestions. There is a video by JL2579 which completely explains how mobs spawn, a Google search should find it if not i'll find it and post the link.

I really need to stop posting when I wake up lol. I was tinkering with the idea of the spawn cages in addition to the trip wire traps, maybe a sticky piston crushing a player against a wall lol.
Thank you for the reply, maybe there just wasnt enough time to have them spawn.
