These lights are used as indirect lighting for a 3x3m Pavilion.
The LEDs are mounted on the rods below the roof and thus to direct
Rain exposed. Therefore, I can not report anything to Feuchtigskeitsproblemen.
Leuchtdeuer: From dusk till dawn (batteries derz still new.)
Light output: for the whole pavilion is no additional lighting is necessary (. You can even play a board game or the card)
Conclusion: Meets requirements! (Derz. No long-term rating possible)
