I turned the light ON again last night on my bed stand when I went to bed. At about 4:30 AM I got tired of opening one eye every now and then and still seeing the light ON...so I turned it OFF. It was still Bright.
I think the LESSON here is that LED lights seem to require a
whole lot less power than anything I have seen.
I am NOT a Global Warming... Tree Hugging... Commie..Environmentalist.....
This is just my small personal experience with one flashlight....
Consumer Reports has a report about light bulbs..Maybe I need to read it.. maybe learn something.
NB
PS: Only us Old Coots will remember the OLD flashlights that would go dead in maybe an hour..if you left it on..inadvertently..
