Hi, thank you for your request.  We do not sell the full panels of 120 for soldering but we have them in packs of 10, so you could buy 12 packs and get 120 LEDs for soldering.  Here is the link:

I see there are only nine packs available online, but if you need 10 packs, let me know and I can put more into stock.

Thank you!
