You need to address this from the prospective of current draw per light. The length is not really the issue. Your continuous current should not exceed 80% of 20 amps, or 16 amps. Now if you were using certain halogen bulbs the current for each might be 1/2 amp each so you could have 32 such bulbs. Do a sample layout in what is called a reflected ceiling plan (Imagine the ceiling plan on the floor) and see how many lights of what current you plan to use and break up your circuit as needed.
Unless you do not have enough space in the service panel it is always a good idea to have each room on it's own circuit. If you want to put 2 rooms on a circuit just make sure those 2 rooms do not overload the circuit and wire it for a 20 amp circuit. Two bedrooms with 8 outlets each and 1 light each is about all you would want on the circuit. I would never put 3 rooms on the same circuit.

Up to 12 on a 20 amp circuit. Up to 9 on a 15 amp circuit. But use common sense. If the circuit will be heavily loaded, as in a home office, then do not install that many.
There are many applications of this acceptor circuit. You can learn more about them with some electrical training programs.

Track lightingTrack lighting has come a long way from its stark beginnings. Homeowners have many choices now and can choose track lighting that will perfectly accent their decor. In addition, track lighting is easy to install, which means it is a perfect weekend project for homeowners who enjoy working around the house.Track lighting is ideal for rooms where extra lighting is needed, but the homeowner does not want to cut holes in the ceiling or purchase costly lamps. This type of lighting is easy to install. Power has to be extended from the junction box that is usually located on the wall or in the ceiling itself. The track itself does not draw power. Only the lamps that are installed on the track draw voltage.Many rooms will already have power present for lighting, which is another reason installing track lighting is so simple. For instance, a light fixture for an overhead light will have enough power to run a track that has three or four bulbs on it. If the room is small enough, no further wiring is required.Homeowners with only a small amount of do-it-yourself experience will be able to install track lighting on their own. It is a simple procedure that is not time-consuming. Track lighting is the way to go for homeowners who want to add a little illumination to their lives.
The maximum number of standard lighting outlets on a 20 ampere circuit can vary depending on the wattage of the light fixtures and the local electrical code regulations. In general, as a rule of thumb, you can typically have around 10-13 standard lighting outlets on a 20 ampere circuit.
The National Electrical Code typically allows a maximum of 12 lighting outlets on a 15-amp branch circuit and 16 lighting outlets on a 20-amp branch circuit. However, these numbers can vary based on local code requirements, so it's important to check with your local authority having jurisdiction.
You can purchase led track lighting many places. Amazon.com seems to have very competitive prices. As always, you should shop around. Online you can find some great deals.
In this type of situation, where there is more than one lighting circuit, a lighting contactor would be used. These types of contactors can be obtained in four and five pole configurations. Make sure that the contactor is rated for lighting loads and not motor loads. A normal switch, single pole single throw, would be used to switch the contactors on and off. A single switch could then be used to control as many contactors as you need to operate the lighting circuits.If there is just one lighting circuit, the total circuit amperage must be known, then the switch would be sized to the amperage of the circuit.
A two-way lighting switch typically has 4 terminals: two terminals for the switched circuit and two terminals for the incoming power supply.
Check with your lighting retailer, not just a hardware store, about a full quote. The price will depend on many factors and can't be determined without close inspection.
