I would doubt that it compares favorably to lumatek zeus at that price point. Never heard of the driver make and while i do have experience with Hongli monos i would not rate them as well as crees or osrams - it looks very much like a chinese rebrand. Spectrum seems to indicate 70cri diodes: a bit more efficiency at a slight sacrifice of yellow and red in the spectrum.
For a low cost item it looks allright, they seem to want to squeeze out maximum ppf/w out of economic components. I would make sure to get full details on aftersales service, in writing what they would do if you were to have problems with it within what warranty period.
Dont wanna tank it but the cheaper things get...
