Isn't a retailer who sells all brands of indoor lighting gear considered non-partisan?
The answer to that question is a resounding
no. In fact a retailer would be the last source you could expect to be anywhere near biased. They will, however, find a 1001 ways to fluff up the products they do resell. If they do "highly" recommend one of their contracted brands over others it is more likely to do with higher sales commissions with one brand compared to another or special kickbacks provided from the manufacturer. Of course there is a fine line of a retail company selling cheap ass junk and promoting it as quality for sales compared to their own reputation, but that usually comes with the retail brand selection in the first place.
Its a bit puzzling to me that you would even assume that a retail business sector be a "non partisan" when their only objective is to sell you at almost any cost. I thought that was pretty much a unwritten fact. As in "we know they are going to lie to us, we know their bullshit is simply a sales tactic, but we will pretend we are interested in the crap they have to feed to us". Of course I still dont know what this has to do with the topic.
