That's a rough one...
Locally they all sell them in small units. (2.5g) for typically 7-11$ depending on where you live and where you can buy. We use the ratio of 48LEDs per 14g tube.
If you can't find any and need to order from us the self tapping screws and paste they are small enough to fit in a small box. Use the code " smallbox " at checkout.
bluwing, I responded to your thread about the wiring diagrams because everyones situation is different and its dependent on how many LEDs you want to run and at what power.
I love build threads and am excited to see it come together!
