Everything is possible but you expose yourself to fire hazard, I'm dead serious! watch out and ask advise from a licensed electrician.
First, understand that your electric washer dryer probably consumes about 5000W, running on 220v, it needs about 22 Amps. Your circuit has probably a 30 Amps breaker which leaves you no room to add anything else. By using it for your lights, you will certainly overload the circuit which could result in a fire.
Secondly, running things in 220v does not save you money on your electric bills. Your power bill is calculated in function of Kw or HP consumed. Your installation will consume the same wattage whether you are using 110v or 220v. However, 220v requires less amperage which could allow for a better usage of your installation.
So calculate the amount of watts you need, then divide it by the current and you will know how many Amps you need, for example: if you will have 3 lights of 1000W, 3000/110=27.7A, it is a very very bad idea to overload your circuit and you will probably need to install fans, pump, airco, etc ... so I would go with a 50A breaker at the main panel wired to a secondary panel where I run my subcircuits. You can never have too much protection. Also very important, depending on your circuit, you need to apply the right section of wires, the right receptor/plug, etc ...
So, make yourself a favor, ask an electrician and do the right thing.
