Thanks, I had not seen the flashlight review site before last evening and then couldn't get into it. I did this morning and Brinkmann has made some design changes since that was written as the 4-pack of lights I bought have some differences in the case design. The back half is now fastened to the front with what appears to be a rolled lip but it is not glued. On and Off is achieved by holding the top half of the case and twisting the bottom 1/8 turn. There are batteries inside.

This review also rates the performance as way below the claims. In actual use I would probably want to use it for a maximum of continous use for 2 hours per night. Over the next few days I will run it in 2 hour cycles to see how many I get before the light level is too low to be useful and report back. I will also attempt to open it at that point.
