Need help with Daisychain light setup

Hi,
This might of been asked before and i've missed it but im trying to daisychain 5 cfl 20w lights together and im not sure what wiring i need, i have 5m of electrical wire for lamps and not sure if it can do what i want it to do...it has a...

max rating of 240V
3 amps,720w
0.5mm 3 core round flex

Will this be safe to use on my first grow in an old pc case?

That sounds like it should be sufficient. But instead of running all those wires in the picture, I'd buy a terminal block and run one leg to it and share neutral. Then you won't have so many pig tails crammed into the pipe.

Thanks whiteflour,
by using a terminal block did you mean like the setup in the pic now?
As you can tell an a complete noob when it comes to electrical stuff.
