Review: Bought two of these for a storage shed to provide light at night where power was not available. Solar panel and Light were easy to assemble, LED light is very dim, may work to provide egress lighting but not much help to work by even with two of these. Pull switch on one unit failed the third time it was turned on. Pretty expensive compared to similiar motion LED Flood light at Sam’s, have one of those in this building (24′ x 24′) to try for working light while using the LED Lights in this review for backup. Storage building is adjacent to new green building at work and trying solar to see if it will fill needs for lighting for few times needed after dark, at this point can’t recommend buying these lights. Picked LED since it will be cold when normally used in late fall and winter, LEDs work better than CFLs in cold weather.
