We ordered these without knowing the total light output of these lights. We were unable to find much information on them online before the purchase. They are of decent quality, I don't have any issues with that, but the light output is just not very strong.
After receive them we found them to be rated at 60 Lumens for the pair, which is 30 lumens each. A 4 watt night light bulb is rated at approximately 20 lumens, to give you a point of reference. Once I put them up on a gutter there was hardly any light down at the ground. We also had one of the 2 units that didn't work.
I am working with the company on returning them now, I hope that goes well.
We even tried these on a fence, so they were at about 6-7 feet high off the ground and you could barely see any light on the fence itself at night. It was in a dark corner as well, so no other lights were competing with it, they just aren't very bright. And this was on a full charge, I had them switched off for 3 days and in full sun, and then also switched on for 3 days in full sun, it made no difference to the amount of light output. They are just not a very bright light, but there was no way to know that beforehand as that information was not listed in the groupon or even on the vendors site.
