I ordered this lamp version 520 lumens, I still received the latest 680 lumens, a good surprise unpacking. This must be explained by the fact that the old model is no longer manufactured (yet less expensive). It illuminates a fine piece high power (220 lumens) or maximum (680 lumens), it is impressive compared to other incandescent lamps not better illuminate the mini mode (6 lumens). The finish is good, aluminum body with AA battery compartment properly seated without play and neither faulty contact. The presence of a selection switch + button is very convenient, it avoids to press 36 times on the same button to turn off the lamp.
However, it is a shame that the switch overflowing slightly on the back, because prevents the lamp from stable to vertical, I often ask the lamps to illuminate the ceiling ...
