Spectrum King/High BaY

What Cree chips does Spectrum King use in their 400+ lights? They do not disclose this info in their product description. Wonder why? Is High Bay the exact same light as Spectrum King or are they made cheaper. Specs seem the same just wonder about the quality of parts. They also make a 500w, and a 600w. Greatly appreciate any factual input.

Thanks!

They use xbd bin led's. They don't disclose that because they don't want people seeing its not a top $$ led (also they don't want to update every publication whenever they change bins). They aren't horrible (far from it), but they are overpriced...
