Review on MalloMe LED Camping Lantern Flashlights 2 Pack & 4 Pack - Super Bright 350-Lumen Outdoor Lights - Portable And Collapsible For Camping, Hiking, And Emergencies In Black by Etai Gopala

All lights worked; however, one of the lights retaining bolt's nut had come loose. It took awhile, along with a bit of clever rubber band work, to get the bolt to stay in place in order to feed it through the bottom of the light platform so as to reattach the nut but thereafter the unit seems to work as planned.As to my best guess, I'd make the amount of light somewhere between a 25 watt and 30 watt incandescent bulb. A 40 watt bulb puts out about 450 lumens, 60 watt puts outs 800 lumens and 100 watt puts out 1600 lumens, so the watts-to-lumens slope is not linear. It's definitely bright enough to see clearly over an enclosed area such as a tent but still a bit too dim to do and serious reading by.As with most battery operated products, it's always a pleasure receiving the batteries with the purchase, and this product didn't disappoint.
