The lamps are well packaged. But unfortunately there is nowhere in the accompanying instructions as you open this to the batteries insert. Turning, levers ..... ?? Ahh ... there are three small screw holes Phillips, but this hardly walk on a normal phase tester or Phillips screwdriver. It cracks and crunches and you get scared that it breaks apart when untwist. After I did today in a hardware store of a globe as its logo, seen almost identical lamps for 4 at the box office have that looked quite stable and anfühlten better and made a more solid impression, I was very annoyed. But you're willing to learn :-)
