We had such automatic battery LED lights already been indoors in use, such as to care when opening the cellar door for something equal brightness when there will only briefly to get something, you need not only to long to the light switch. We have good experiences, but outside the requirements for such a lamp are still times higher: first, the surface to be illuminated is larger, be the equipment designed for other needs waterproof.
In the latter point there with this model of Mr. Beam no problem now it has survived several downpours with us and continues to function perfectly. I've put up sometimes and looked not to notice of moisture. The plastic case seems so do his service, it is also stable. Attached it with two screws, the rotation around two axes allows the detection range of the motion detector adjusted quite well.
Other can not be set: Neither the twilight level at which the unit responds, nor the sensitivity of the motion sensor, nor the duration of the automatic headlight pulses (around 30 seconds). These are all things that I've seen at other adjustable (network-based) models. Here it is take it or leave, you have to take it as it is fixed.
There are other ways: by remote control the lamp can be independent of twilight and movement on and remains on for a fixed period of 1 or 4 hours or until they are off again. In exceptional situations like such a continuous operation times be useful, but if that happens regularly, keep the (Not included) batteries not last long. In our attachment to the garden path, we consider it with the classic method: Will you have time for more light, you wags his arm to activate the sensor again
As for brightness, it is sufficient for the surroundings of the lamp. Larger areas can not effectively brighten it's just not a floodlight, but only better LED lamp in the highest level adjustable. For its application range the device delivers an acceptable performance. Gift but you do not get the our indoor models (brand appliances) cost less than 10 euros per piece and bring about the same brightness. The outdoor capability so has their considerable price.
