Both examples, with some tweaking, would make decent signs. Unfortunately they make terrible logos.
Step back and try to remember just what a logo is supposed to be. A brand, much like a cattle brand. A simple symbol representing the organization. The operative work here is 'simple'.
A logo is not a sign or a newspaper ad complete with organization name and ancillary information, tag lines, and perhaps phone and address as well. Unfortunately the vast majority of logos, by those who damn well ought to know better, seem to feature these sorts of things. Admittedly including the name of the organization isn't necessarily a deadly sin but the rest of it is.
