But then again... It is eBay. Some are good finds and some are just assembly house rejects. I will get a couple of these units and confirm first...

It would be neat to throw those side by side. Both showing close to the same lumens @10w.
I deal with LED lighting for general lighting applications through work and they all seem to vary. Rated hours can be from 25k up to 100k, CRI can be from 60 to 90(visually a huge difference, 100 being daylight). The pricey LED fixtures(non marine) score high in these 2 categories.
I would post pics of the differences between the 2 fixtures I have but they would both look like crap with my photography skills.
