These might actually be rebranded lights made by someone else, who I'm not sure though.
I know Browning's
Odyssey line of lights (2000, 3000, & 4000) are Lightwave's 2100, 3000, and 4000 respectively, Browning has just rebranded them. Perhaps Browning did the same with these?
If you're looking for a review or whatnot, try looking under other brands that Browning may deal with, and try and find these lights by the original manufacturer, good news though, they should look the exact same since Browning didn't change Lightwave's designs at all.
Try looking under "Orbyx" as a manufacturer. I've seen lights much like these in RadioShack under the "RadioShack" brand, but it's actually rebranded Orbyx lights.
EDIT: The manufacturer Shykuang in Taiwan makes these I believe. Shykuang also makes lights distributed under different names like Nuwai and Xenergy. You can see the page for the product at Shykuang's site
here. They even name the product "Browning". Lights by this company generally get good reviews, but you should look at lights individually anyways to judge their quality.
