The LED spotlights (in my case, in 2-pack) No batteries are included, you have to purchase it separately. Pro radiator 3 pieces, in total 6 pcsType Baby C LR14 or even called. It recommended alkaline batteries. The multilingual description, intended for the European region is well and clearly written. After assembly with batteries the radiator can be mounted with a screw for example very simple. An axis can be rotated, allowing a meaningful orientation. Well done here are the catches, so that an adjustment of itself can not occur.
In darkness, in range of the detector and movement of a heat source (such as humans, animals, cars, etc.), the LED is activated. The brightness is somewhat exaggerated in the product photos. It's just so that you can find their way, enough to say so. (If you need more power, intervenes if necessary to this model.) If the detection zone is exited or is no longer moving, the spotlights for a further 30 seconds. The light is pure white, warm white no. The wide beam is sharply defined. The life of a battery pack depends mainly on the burn time and only very little after standby.
A great product at a reasonable price! Who cares only for the use, for the end here my review.
For the technically curious, here are a few details:
The radiator receives only 0.06 mA in standby and 200 mA in operation with LED. It switches at
Gives you the specifications of Duracell Baby C alkaline battery faith, makes this 7800 mAh. From this theory, the following calculations show:
7800 mAh / 200mA max. 39 hrs. Operation of the LED
7800 mAh / 0.06 mA max. 130,000 hrs. / 8760 hrs. (1 year) max. 14.8 years in standby ;-)
Thus, the battery life depends almost entirely on the effective use of LED. Exciting whether the device undesirable on natural factors (storms, rain, warm wind gusts, etc.) is still responding. Experiences I like to wear for when needed. Until further notice, my buy recommendation.
I hope I was able to bring a little light into the darkness.
