I am currently installing 10 recessed lighting in my living room: 8 small ones (50W) and 2 big ones (60W).
Somewhat related is my kitchen: It used to have a 220V plug for the electric range. The range is now gone and replaced with a gas-unit so the 220V plug is no longer needed.
Question:
My panel is already full


. Instead of installing a subpanel, can I use the 220V circuit? Of course I somewhat understand that this is actually 2 110-lines. Would this be ok to use by splitting the 220V?

Thanks.
