Since you do not give me all the fixture infor.. I'll give you a general one.

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.
