I actually did some more playing around with the light yesterday to simulate blackout etc.
It seems upon powerloss then restart without network connection the light defaults to utc+8 and runs that schedule, it seems to have a real time clock to follow but it loose the time zone. I worked this out by putting the light on its own vlan and blocking its access to the internet and you can read the html config page where it prints the lights time. when internet access opened back up the light corrects itself.
Further to this, a power failure where the light starts before the network will put it stuck in its fallback state and it doesn't seem to try to connect to the network again, a simple power cycle of the light seems to resolve this. No need to open the app at all.
I was testing this along side my g6 radions xr30 blues. I was running the radions at 75% all channels, for the exact same par from this light I had the white channels at 25% and all others at 50%. Measured using an apogee mq510.
Price wise, in Australia radions are going for $1800 now, I got this light for $545 landed, however prices now have dropped to $445.
Is a Radion worth 4x as much as a a8? Probably not.
