In common, there are 2 pairs of wires coming out of the coralive ballast box (3 wires: black-white pairs and red-white pairs, ground not counted).
The pairs black(or red) and white usually are 120v supplying for led light driver, fan adapter... You have to check this black wire by looking at the power switch on the box. It just hooks to the switch's 2 wire port and comes out of the box leading to the fixture without going to the ballast.
Please use Volt- meter to check them.
The pairs red (or black) and white are for the metal bulb.
Because coralive is using eu standard, it's ignitor is a superimposed one.
This means it can stand alone using it's own coil to boost from 190v to 4000-5000v. So it is wired simply and differently from the North Ame. one.
So:
First, from the ballast
White (com) wire goes to N terminal (neutral).
Red ( hot) wire goes to B (boost?)
Second, From bulb's 2 socket wires
One(red or whatever up to you) goes to Lp (lamp).
The other(color up to you, but white is recommended) wire goes to N
Please note there are TWO whites go to N.
The wire's color sometimes tells you nothing. To be sure check them all:
There is only one hot wire (white one is another one but not hot) coming out directly from the coralive's ballast. whatever its color is, You must consider it as red wire for connection above.

we are getting there,
I opend the ballast and the black whire that is coming out is conected to the switch.
so gust to go over it:
the red whire is going to B (boost)
the white will go to N and is conecte at the same time to a whire running to one of the bulb soccets.
the other end from the soccet is going back to the igniter and wil go into LP
what do I do whit the black whire coming form the ballast ?
what do you mean with: It just hooks to the switch's 2 wire port and comes out of the box leading to the fixture without going to the ballast.
Please use Volt- meter to check them
how do I check it, what position do I have to put the multy meter on, and what should I read ?
