This lamp does not light up the moon but it is not what is asked. She is very well thought out, ergonomic and system induction always a small effect on the environment. The LEDs are powerful enough to replace the torch papi. The battery runs down, obviously, but it's not a survival torch. The torch is supposed to be on its base most of the time. This is the second time I buy one because I was forced to give one to my stepfather.
