I've never seen the Amazon version in person so I can't comment on it.
The Arena light and the Perimeter light I'm very familiar with. The root problem on both of them is they don't have eggshell style grate diffusers. Those diffusers keep the light pointing down, and prevent it from going sideways. All the Brunswick lights (both home style and commercial GC light), all the Diamond lights (from their first ones in the early 90's thru today), and all the Littman lights have this eggshell style grate. It makes it comfortable for the player, and the spectator.
The Arena and Perimeter lights, in contrast, have a frosted plastic diffuser without any depth to it. It allows the light to escape sideways, in addition to downward. What this means is the player when down on a shot gets the light from the next table over in his eyes. Spectators walking around the room get light in their eyes from all directions. It's quite uncomfortable. It's like being in a hospital operation room. Those lights changed the entire atmosphere of the room from dim and comfortable to an operating room.
The Arena is worse than the Perimeter because its brighter.
As far as the dimming control, that was an extra cost option on both brands. It was not standard. You know how that goes... most room owners and homeowners bought the cheapest one, that didn't have it. Just like the metal wire ball tray on a Diamond was an extra cost option, and all the one pocket players put their balls on the floor by the legs, because the room owners rarely paid extra for it.
Now if this Amazon one still doesn't have the egg-crate diffuser, but does at least have a dimmer as standard, and as a bonus temperature control, I'd rather go with that unknown than 2 lights I know for sure are uncomfortable.
