I made them from little led's from china. Pain in the A$$. I used a tutorial from here and online with my own twist using things on hand. Instead of PVC, I used little metal canisters with clear lids attached to hooped landscape fabric stakes - that lets me point them however I'd like and I can add whatever color lighting gel into the canister to change colors.
Ah, the code word there being PIA Do you remember what amp each light is? I found some 3 amp ones on Amazon-they have 16 color choices via remote control. I'm freaky about getting the lighting right, which you did.
