Question: About how many lumens does this light produce?
Document: Not too many solar charged LED outdoor lights work well, but this one does. The ON/OFF switch was very confusing, had to play with it to figure out when it was actually on. It includes a little micro-key to push a micro switch inside through a dinky little hole in the case. A paperclip would work also.The light is very bright when you walk near it, then after a while, it dims and stays dim until you walk near it again.
I purchased this and other brand frostfire, found out both are exactly the same , but this one is $5 less, I guess they both OEM from same company. so I keep this one and return other one. Seems well made, also I like the Lion battery the most, Unlike NiMh battery will not last long at many charge and discharge after so many time usage.
We have only recently installed these but 100% of the many lights worked - no DOA or faulty units at all. We can't currently address the expected/experienced longevity of these units but they have the best battery technology available and are well made so we expect great things!The only minor thing we'd recommend is have these available for purchase in a in a UV-resistant white color for folks with white vinyl fences/pergolas/trellises, The black looks fine, but we'd prefer white.
Love this light
Works as described. Used to light side of garage.
I am very pleased with light. Super bright, no problem after getting wet from rain.
