The key is provided for installation (ankle screws) but neither drill nor the courage to engage in DIY are stamped Taotronics.
In reality, this is really very simple, just drill a hole to screw the lamp and start inserting the needle provided in the suitable hole.
Jai this lamp installed as recommended, about two and a half meters high, the top of the flight of stairs that leads to my front door. When I go home at night, the light lights up and this is becoming easier to find the right key to insert it into the lock!
To quibble, one might find that slightly lacking lighting power but perhaps that there is no just enough sun here
Efficient, low-key, no frills, great product!
