I have a quick question.
Running OS6.3.1 with adding AP225s whats the main difference between PoE and PoE +
Reading the data sheets it seems you still get AC with standard PoE but only 3:1 on 2.4GHz but full 3:3 on 5GHz. Could anyone who has deployed these on just standard PoE please give me some feedback,as at the moment thats what our current network switches are.

We currently have Cisco 2960S PoE + switches and looking at adding AP225s we shouldnt have a problem with these switches should we? The only reason i ask is we've been told that we might have problems not being able to use the AC feature.

The best method for utilizing both switchports would be to do a cross stack port-channel so that if you lose one switch, the AP simply reboots and is able to come up on the other switch (second port).
Since most PoE devices only have one powered-device circuit, they cannot sustain power across both ports and must drop power (reboot) and renegotiate on the second port.

Here's a 225 with both radios in use. 5G using 80MHz channels.

We recently did some new testing based upon the new versions of AOS and determined the following maximum loads:
Unrestricted mode / Max DC power: 15.5W
Unrestricted mode / Max Powered Device (PD) power: 17W
Restricted mode / Max Powered Device (PD) power: 13.5W
* Above exclude USB consumption
We will be updating the datasheet shortly.
