While this LED light strip from
is super bright (brighter than expected), it does get hot rather quickly (after just a few minutes). So, these definitely cannot be left on when unattended for safety reasons.
However, it conveniently has sticky tape on the back and comes with a handy remote that lets you change the brightness and effects. The strip is 16.4ft long and includes a rather bulky AC adapter. It's also not listed as waterproof, so for indoors only!
