Review on Linkind Solar Spot Lights Outdoor, 6500K Daylight IP67 Waterproof Adjustable Panel Garden Light For Yard Patio Trees - 4 Pack by Patrick Burton

There must not be a reputable standard for measuring Lumen brightness level, because ".Max of 350 Lumen." claimed here is not real.maybe if they put the Lumen tester right up to the face of the light it's 350 ? I have a "Better Home and Gardens" solar, color light from W.M.

that only claims 120 Lumen and is twice as bright as these (but has a big reflector).but it has it's own problems.the battery case inside is such thin plastic that the battery spring breaks the plastic case in every one of them, so I switched to these.)I do LOVE how much more adjustable the solar panel is on these light, and they do last all night, so the improvement in solar conversion efficiency makes a difference.They are also better water-proofed than my W.M lights, one of which did fill with rain water a bit, these are bone-dry after months of extreme cats-n-dogs Florida rain !.but I've found I have to double or triple these up to adequately light up trees and landscaping outside.so take that into account when planning how many to buy (I ordered the $80 6-pack).I should add that despite my wanting them to be individually brighter, the neighbors have commented on how nice the 2 out front look.I just need to add a couple more and I'd be satisfied.
