Welcome to cpf!

The easy way to get led lights is to buy them. The harder way is to read existing threads and do a bunch of research about how to build them, then acquire lots of parts and put it all together.

Some questions for you would be: What is your budget? Do you have any machine tools or access to them? You already have the battery charger and batteries? Do you have a soldering iron? How long will you use the lights at a time? Do you care if they get hot?

When you say 1" O.D. tube, do you mean you want to utilize PVC pipe or metal pipe as the housing, or just that it should be 1" O.D.?
