Ok here are DIY pics of the halide.
First the halogen lamp $9 and the 70 watt ballast $42 shipped
Then i drilled a hole for the wires and pulled them through to be soldiered
Here are the connections done with heat shrink tubing and the hole siliconed
And its ready for a double ended bulb
I still have to ground the ballast. I cant get soldier to stick to the case. I put a ground wire on it to be screwed down when its mounted. Sorry if its kind of vague but i havnt ever done a "how to" post.
