Thanks for doing the work, useful info to have.
Your last comment in the video aside, knowing the APR 3 - 6" off the axis would have been most usefull. That would indicate the spread and help people like me to decide if they want one or two, for say, an 18" wide tank.
The price also increases substantially for longer fixtures. When comparing to Finnex, one might consider that a double ramp timer is about $50 all by itself.
