This link is the schematic I used to make the flag pole. I used 1" PVC instead of the 3/4" PVC they specify. At the top of the pole I put a "T", and capped each end. Drilled a hole in each cap and used epoxy to secure solar spot lights on either end of the "T".
The solar lights where purchased at Home Depot. I can not locate the link for the lights. They come in a package of two lights and are 20 watts per light. The cost was about $20.00 for the set. They could be lower by now. They also come with 2 rechargeable batteries per light. I also replaced the 650mA capacity batteries with 1600mA batteries. Either set of batteries work, but I wanted the lights to last longer, so I used larger capacity batteries.
Thanks for the interest in the flag pole. Here is a link for one of threads I posted a while back. It gives you a look at the flag at night.
