I’ll give the credit to Manker’s R&D TEAM. They’re the original design many great popular lights such as E11, U21& E14. All others manufacture Lumintop, Astrolux, utorch, Mateminco just copycats of Manker’s design. However, Manker needs to improve their UI & build quality.
Zebralight are great over all lights not much to complain about! Tint issue is basic on Cree emitter problem, IMO. However, the Whole ZL produce line up are lack of new design. Similar design use for years only slightly change & improve. I pretty much lost interested their new SC64xx , SC600 mk IV & H604xx this year.
Zebralight’s produce Reminds me of Apple’s iphone 4 to 8+ :weary:
