PowerSave Advanced Technology Remote Control Microwave Sensor Slimline Energy Saving LED Security Flood Light (20w Flood Light / 200w equivalent) [Energy Class A++]

The biggest problem is that the unit is triggered by rain. This is not just when set to the maximum range (7 to 8 metres, their figures), but also 75% range (5 to 6 metres), 50 % (3 to 4 metres) and 25% (1 to 2 metres) range. The intensity of the rain was medium (not light or heavy rain). Rain triggering is inherent to small, cheap microwave detectors. The "slimline" profile results in a wide detection beam (on the box they admit it is 180 degrees). So even with the unit tilted downwards the sensor is "looking" upwards. So falling rain looks like an approaching object. The manufacturers claim that: "Microwave detectors are more reactive to movement across the sensor than towards the sensor." The reverse is the case in fact. The principle of operation is the Doppler effect in which the microwave sensor produces a detection signal when an object approaches or moves away from the detector. Motion across a microwave beam produces no detection signal. But with this light the beam is so wide falling rain approaches the sensor triggering the unit. Well designed intruder detection sensors have fan shaped beams such that their beams are wide (up to 180 degrees in the horizontal plane) to detect intruders, but narrow in the vertical plane so that rain does not trigger them. One of the disadvantages of microwave detectors is that they are triggered by more or less anything that appears to move towards or away from them, such as: rain, flowers, trees, washing on the line, cars, the reflections from switched on fluorescent light and so on. With such a wide beam and because microwaves do not discriminate against objects cooler than body heat, false triggering is bound to be worse than with PIR (Passive Infra-red) detectors. I know this because I used to design microwave intruder detectors for a living. The advantages of PIR detectors are that, in principle, they are only triggered by the movement of objects at body heat, and the beam shape can be easily optimised at the design stage and again at installation by the user using tape to cover parts of the sensor lens.Another problem of "slimline" units is that there is essentially no light reflector focussing effect, so the light beam angle is also practically 180 degrees. The manufacturers claim 120 degrees but that is probably just be the brightest part of the beam. Depending on how the unit is sited the light overspill might illuminate your neighbour's bedroom which might make you unpopular. And if your unit is switching on and off continually when it rains it could be extremely annoying, and wasteful of electricity. A deep reflector, rather than a slimline one, would reduce the light overspill somewhat. Another problem I found was that it refused to work on light level settings other than all day and night. This was because the light level sensor is too directional, rather than sensing low ambient light and I need to mount the light facing a street light.The manufacturers claim that a 30 W LED has the equivalent light output of a 300 W conventional incandescent lamp. Although some suppliers claim 10 to 1, this seems a bit optimistic. Many suppliers only claim 7 to 1 so that a 30 W LED is probably closer to a 210 W conventional security light lamp.Another problem was the very short mains lead at 9 1/2 inches which was just 7 inches beyond the bracket, so I needed a waterproof three lead mains connector. The back of the light is permanently sealed with no access screws so you cannot replace the short lead with a longer one.Another problem is the instructions. The translation from Chinese to English and the lack of explanation is confusing. I think that the "Day & Night Sensor" button enables and disables the ambient light photocell sensor so that the unit can be made to operate in the daytime which is useful for testing and setting up during the day rather than having to wait for night time. I assume that the button labelled "Dusk to Dawn Photocell (No Sensor Feature)" means the unit can be made to operate from dusk to dawn (although this appears to contradict the "no sensor feature" part of the label). I assume that the button labelled "Night Only Sensor" means that the unit then only operates at darker times of the night, rather than the longer dusk to dawn time. I assume the button labelled "No Feature" does nothing. The sensitivity control buttons on the hand controller do not refer to the day/night sensor sensitivity but to the detection range adjustment. I mentally scrub out the label "Sensitivity" and substitute "Detection Range".In summary: it looks nicer than conventional units, the LED makes it potentially more reliable than halogen filament lamp units, being programmable by remote control makes it very easy to set up once you have decoded the unclear and incomplete setting up instructions, but the rain triggering problem makes it unfit for purpose.So I have to decide whether to fit a diffuser or shield over the ambient light sensor, and a metal shield over the unit to stop the microwave beam looking upwards, or to disconnect it, take it down and send it back.

I used this 10w light to replace an old conventional floodlight. I do not need to illuminate a large area but to light up the patio and side of the house when walking around or to dispell intruders. I have found the 10w size to be perfect and for me anything else would be overkill. Choosing a 10w light not only reduces power useage but makes the device significantly smaller than the traditional flood lights.The main reason I selected this was because of the remote control setting as my lights are very high and incredibly difficult to just pop up a ladder to make a quick adjustment.I suppose the best endorsement I can make is after fitting one I bought another three for other areas around the house. The extra price for this technology is certainly worth it in saved man hours as they are so very easy to fit.The only minor negative i have experienced is the tendency for very heavy rain to trigger the light. If that is a problem they can be switched off via the remote. The other point is that the device cannot be opened so a waterproof connector is used. These can be obtained cheaply elswhere.

This is a 1st generation microwave detection flood light. The concept is brilliant and the performance is consistent, but it's not as per the description. Microwave detection range is only 4 meters. The pig tail is exceptionally short which will causes substantial installation problems (you'll need a waterproof choc-block box). Lastly, the remote is line-of-sight infra red. This means you can only adjust the floodlight in low light while stood in front of this flood light. If none of these consideration is a problem for you; this is a fantastic product.

Easy to connect, 3 core wire. Looks great... Smaller than imagined... But in a good way. Looks a bit like a tablet pinned to the wall.Bright enough to read a book under and be noticeable... But not so bright it'll light the whole street up. I would say perfect for most people.The remote is great. Just flick to permanently on if you want to read or chill out within the area and as soon as you're done, flick it back to sensor mode. Sensitivity of sensor can be adjusted... Even hot water at the drain was initially setting ours off, but fine when we dropped the sensitivity.No expense spared with stainless steel bolts in the unit. Manufacturers who use stainless as opposed to the cheaper chromed/zinc bolts tend to be making a product thats designed to last!No other outdoor light on Amazon can cater as both a security light and a convenience light within the press of a remote button. I'm Impressed. Highly recommend. Thanks.

Seems to work well and the motion sensor seems quite reliable provided it is not turned to full sensitivity. Compact and neat. Relativily expensive compared to other motion sensing lamps but probably worth it. The only criticism os that the connecting cable should be made longer. As this product will invariably be mounted outside and the connections will have to be brought inside , the shortf cable makes an external connection neccesary with the obvious danger of weather ingress. The cable should be at least 1m long!

Please don't buy this light if you want a movement detection light. It was either unable to detect any motion or on settings 50% and above was on constantly. Even the supposed time-on setting did not seem to work. I had tried a cheaper and similar light, and to be honest it worked better than this more expensive variation. Really disappointed that this did not work for the purpose I needed. Having to disinstall is another real pain..
