Quoted from ryanwanger:
The non-surface mounted stuff is essentially the previous generation of the technology, and won't last nearly as long. We've been working on changing our messaging to make sure it's clear to people when they're buying.
Do these types of bulbs sell that well? I know for me once I got my hands on your smds I never considered buying the others ever again. Maybe as a backbox bulb since they are not as bright.
