Retrofit MH lamp to self driven LED

So I'm trying trying to replace a MH to an LED. There are three wires coming from electric line black white and green.

Those three wires then go to ballast (or so I'm told I don't know anything about electricity) I'm trying to connect the three wires directly to the socket for the self ballasted corn cob light (led bulb) the problem I have is I need to wire the censor so that it goes off at dusk automatically

there is a red white and black wire coming from the censor

And two white(together) one blue and one green coming from the socket. How do I connect these wires
