A great little product-LED solar motion security light which is well designed, robust, makes maximum use of its compact size and at under $ 13 I believe that's excellent value for money.
This is essentially a safety (possibly security) light which is activated by a PIR (passive infra-red) sensor and contains some form of battery/capacitor to store electricity and a solar cell to recharge itself. The unit is rated "IP 65" - Ingress Protection "6" for dust (6 is the the maximum score denominating "dust tight") and "5" for water (protected against water jets but not immersion) - which I believe is spot on for outdoors in the UK, mounted 2-3 metres high on a wall or post. The unit is completely sealed though has 4 screws on the back so could be opened however there may be tamper-sensitive measures such as a sticker on the inside that rips when you open so you may invalidate your warranty by poking around; I have not opened my device. The ABS case is very robust, not cheap thin plastic, with the solar panel on the top at 45 degress and the bank of 20 LEDs on the bottom, also at 45 degrees. (I mounted mine on a fence pots overlooking my driveway - see pic.) There is also a rubber-feel on/off push button. Having the on/off button on the front is the only weak link in terms of using this as a security light for obvious reasons but then this is not sold as a security device per se so that's not a complaint, just an observation.
The device comes wrapped in bubblewrap in a strong but simple brown box with a small instruction booklet and a pack of 2 screws with wall plugs - see pic. The 'CE' mark confirmes compliance with EU safety regulations (always nice to see) and the box states the device has a one year warranty.You can also visit http://www.amztk.com/ledsolarlight/
Installation is a doddle with no mains to connect to and only 2 screws. The LED Solar Motion Security Light is not heavy (~250g) so providing your mounting method and medium are solid you should have no problems. I screwed into a wooden fence post and it's rock solid. Remember to mount the device facing South and with a clean line of sight to the sun for most of the day.
The test: Well, timing could not have better really as we've just had 2 days/nights of intermittent heavy rain - those big heavy raindrops that manage to soak you inthe few seconds it takes to run to the car! I went outside in the evening during a pause in the rain to test the device works as described and take a photo. It does indeed do what it says, automatically lighting up an area of my drive when I walked into the sensor's range. I took a pic (see below) but my phone struggled in the relatively dim light. The 20 LEDs together are very bright even from 4 metres away (mounted 2 metres high) but the 'pool' of light hitting the ground does disperse over distance - this is not a 'spot' light, the beam is wide. This morning, with a day off work, I have used cardboard and tape to cover the solar panel (the device automatically senses the ambient light and does not activate the LEDs if there is plenty of ambient light already) in order to do the distance/angle testing. My calculations are that 'face on' the PIR activates the light at (minium) 65 degrees i.e. the device is mounted 2 metres high and I am 4 meters away. From the side that drops to around 30 degrees i.e. about 1 metre away from the device.
The verdict: I'm very happy. I often go to work when it's dark, particularly in Winter of course when many of us do, but I really did not want to run a power cable across the garden to the drive so this led solar motion light device is just the ticket. At under 11 quid I think the value is very good and am considering buying a second to mount above the door on the garden shed.
In a word, this LED solar motion light really great light and exceptional value, also make our life more convenient .
