Thought I would chime in since I'm using the SAF lumina in my network: The standard Lumina at 11GHz does up to +12 dBm at 256QAM and +19 dBm at QPSK. SAF designed this radio specifically for lower power applications (solar etc). and has a typical power consumption around 25W per unit.
They have a high power model that does +25 at QPSK and +17 at 256 QAM at 11GHz.
