I could not leave it and have times the backplane ;-) screwed Built is a 900mAh lithium battery, which is glued with double-sided tape on the back cover. Centered in the housing a circuit board is attached, also this entire interior is protected by a second inner wall from dust and moisture. I uploaded here a photo to.
Included are two plugs and two screws (requires only one screw + dowel) and a small wire pen to operate the hidden, or protected from rain on / off switch. If you should lose the time also works the wire of a paper clip. I'm going to the lamp but comfortable with double-sided tape (not included) fix.
The burn time is about 35 seconds, the sensor detects at this time another movement, the burn time is not automatically extended again to 35 seconds, ie the LED's go-between from as long as one stays in the sensor range which I find convenient and good. The detection range of the sensor is about 3 meters.
I did not receive the solar light as a test product and can recommend it. Who even unlit corner in his garden, on the terrace or in the courtyard, this can cover to move so quickly and easily without a cable. Of course, the bulb should daytime gotten some sunlight, so that the battery can recharge.
