Maxspect is a decent brand but has been retooled 3 times in the last 16 months. It is one of the only fixtures that has legs and can mount on a tank like a t5 fixtures. Still have clusters or pads so not uniform coverage, unless you are listening to Chris Conti VP of sales Coralvue marketing hype! Then it could cover a 48x24 front to back , no dead spots! I tell you what, you buy it and I will bring my par meter and prove the hype to be hype.
The other I am unfamiliar with, you have a link you can copy and paste?
