In the context of my post, it's not a cartel light. I.e., not one of the common variants of imported Chinese lights (rebranded, etc.). That puts it in a relatively small group of lights.Az2000 what makes their light sogood?
I agree DIY is a good option too. Some may have to rule it out due to time/talent restrictions. In that case, ruling out one of the few retail lights may not be productive. The OP seemed to suggest this line of pragmatism vs. principle when he stressed that his complaint wasn't about the light, just his treatment.
That's what brought the Seinfeld bit to mind. Probably an over-the-top comparison. But, if I were getting into LEDs and realized there are only a few good choices out there, and got on the "wrong side" of one choice (quotes suggestive of Seinfeld episode), I'd regret that. Especially when the provocation of the surely treatment is understood (the disconnect between "I can't wait 2 weeks, this is a deal breaker!" and "but, if you'd give me a discount on a bigger light in 2 weeks....").
I'm sure the OP didn't mean it to sound that way. But, anyone can see how it could strike the wrong chord. I think it's unfortunate the OP has lost one of a few choices over a misunderstanding during a time of stress (immediate flower demand, moving).
