    I've used a multi meter to suss out the pins on the twin lamps
    So,
    with the lamps upturned, facing upwards and pins going from bottom to top
    it shows that,
    Pin 1 is live brown
    Pin 2 is Blue Neutral
    Pin 3 is Hot wire Black
    Pin 4 is Earth

    [very important]

    The Ballast manual says,
    Hot Leads 9,10
    and
    Cold leads 11,12,13,14
    should be separated as much as possible

    The ballast manual says,

    SK I Luminaires: earth of ballast housing required
    SK II Luminaires: no earth required
    Lamp connection with twin ballast should be made with symmetrical wiring

    Question 1:

    SK II could be the "twin" lamps, so no need for earth
    and
    SK I must be single tube, there for requiring ballast

    I'm thinking otherwise though, because single tubes always have a built in ballast
    or am iI wrong?.. hoping I don't need to earth,
    because
    I feel that ballast cold leads 11,12,13,14
    need to be filled by lamp wires blue and green/yellow
    so no need to attach them to ballast casing?

    Question 2:

    I see that earth pins on the lamp are at 4
    Does that mean they should be separately slipped into Cold Lead ballast 13,14
    With Blue Neutrals separately going into Cold Lead ballast 11,12
    Thereby leaving
    Hot Lead ballast 9 for the two brown lives twisted together
    and
    Hot Lead ballast 10 for the two hot wire blacks twisted together?

    Also

    On Ballast 3,4
    I find that the mains lead has brown live and blue neutral only,
    so
    am I right in thinking that, if hot lead 9 will house the two live browns
    then going from bottom to above in the same fashion
    will mean that
    Mains live will be ballast 4
    and
    Mains Neutral will be ballast 3

    thanks in advance

    Try writing in English not American and may be we will understand better. I think we are looking at something like this ballast.jpg Ballast2.jpg It says earth to casing non of the terminals go to earth. I am reasonable sure the lamp holder is Lampholder.jpg counting from left first pair one heater and second pair other heater. So
    Pin 1 heater 1
    Pin 2 heater 1
    Pin 3 Heater 2
    Pin 4 Heater 2
    But since I can't find any pin number I don't know for sure, but likely the output from the ballast is isolated from input so there is no neutral, hot wire, or earth as such.

    No.
    Fluorescent lamps do not have pins described as any of those.
    The wiring diagram is printed on the ballast itself - all that is required is to connect the lamps as shown in that diagram.

    The 230V input connects to the 2 input terminals. Earth connects to the metal case, normally via one of the screws that fixes the ballast into the light fitting.
