i think those are those oddysea/jebo light that people have had catch on fire many times. if you do a search on google you can read many horror stories about them. however that might be a new version and it might have gotton fixed. The fires from what i hear are one of the main reasons they changed their name from oddysea to jebo, so they could try to worm their way outta it.

not 100% sure but i'm pretty sure. So like the others said make sure to do lots and lots of research before you buy any lights!
