In parallel.
Yes, you are limited. If one 12V down-light requires 50W of power then 20 down-lights will require 1kW. Something's got to give as more down-lights are added. The voltage might drop so as each light is added they all become dimmer or the power supply might over-heat due to it working so hard. It's hard to knowing exactly how many down-lights you can put in parallel unless you have a power supply manufactured for down-lights and it has the manufacturer's recommendation.

What is the total voltage of batteries connected in parallel?
When batteries are connected in parallel, the total voltage remains the same as the voltage of a single battery.
How many battery strings can be connected in parallel to a rectifier in telecommunication system?
6
Are the car battery cells connected in a parallel or in a series?
Sereies, with each cell about 2.2volts
Two resistors are connected in parallel to a battery What must the votlage across these two resistors?
Both resistors will have the voltage of the battery.
What is a device that used to convert chemical energy into electrical energy a group of voltaic cells connected together on a series or parallel connection?
A battery is a device that converts chemical energy into electrical energy. A group of voltaic cells connected together in series or parallel form a battery.
Which part of the battery is an amp connected to in a car?
An ammeter must be connected in parallel to the circuit. If you do not understand the difference between parallel and series connection then you should leave it to a competent mechanic/electrician.
Two voltage sources can be connected in parallel when they are equal in?
Voltage sources connected in parallel should have equal voltage. Otherwise the stronger battery would attempt to charge the weaker creating a lot of heat and depending on the type of battery there is the chance of explosion.
How does the voltage across a parallel plate capacitor change when connected to a battery?
When a parallel plate capacitor is connected to a battery, the voltage across the capacitor increases as it charges. The battery provides a potential difference that causes charges to accumulate on the plates, leading to an increase in voltage until the capacitor is fully charged.
What is the voltage when batteries are connected in parallel?
When placing voltage sources in parallel, the total voltage is the same as the individual battery's voltages. For example: If I was to place 4 "AA" 1.5 volt batteries in parallel with a life of x hours, the out put would be 1.5 volts with a life of 4x hours. note: never place batteries in parallel that are not in the same condition (charge, voltage, ect...).
What is an example of a parallel curcuit?
When you have a light bulb in front of each other (all connected to wires to a battery)
Does batteries connected in parallel increase the current capacity to the circuit?
If each battery is identical, yes.
A 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor What is the current in the circuit?
If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in series, the current in the circuit is 1.0 amperes. If a 9.0 volt battery is connected to a 4.0-ohm and 5.0-ohm resistor connected in parallel, the current in the circuit is 0.5 amperes.
