Absolutely not weatherproof.
on 19 September 2013
Other reviews mention ingress of water. Too right. The marked "weatherproof seals" indicated on the packaging are not at all weatherproof. We get really heavy sheeting rain here, and this device had so very many ways for water to get in. There was a rubber backplate but none of the other seams and openings had anything resembling a proper seal.
LOTS of silicone grease seem to have done the trick (lots of places to put it) but don't use it on the universal joint on the lamp head or it will become too loose. Instead point it where you will and cover this joint well with a harder sealant (my preferance is polyurethane). The rubber cap at this point is a bit of a joke. It doesn't seal anything!
UPDATE - six weeks later- one unit not working- despite half a tube of silicon grease it is full of water. NOT a write off- the electrics are all ok. Taking the pcb out to dry it the external on/off switch broke. Not deadly- the internal on-off switch is ok, just need to seal the external switch hole. Ahh- I see why the PIR has caused problems to users- it is on a LOOSE PCB and can very easily not be in good alignment with the small window. I may need to remove the window and put in one of my own. Note that this unit is in a VERY exposed position- not unlike being under a waterfall with the rain we have had recently. The construction is simply not up to UK weather.
Another unit also six week old has the light unit inside a greenhouse, snug and dry, with the solar collector on the outside - continues to function well.
The AA batteries are not what you might expect- it is a single sealed pack soldered in, of 1st Generation low capacity NIMH batteries. They could be replaced with care but it will probably be a lot easier when the time comes to replace the unit. It was not possible to precharge them with an AA charger as I had intended!
The batteries are held in the lamp unit, which has an on/off switch (see note above) - if you need access to the switch to limit lamp use in badly dull weather, make sure you can reach it.
The light is slightly focussed rather than wide angle for floodlighting, with a definite sharp fairly small area and a wider but paler light - ideal for lighting doors or steps.
In a dark garden the light is really quite strong- in the more central area.
The PIR detector is quite small and also fairly focussed, so make sure the PIR is pointed where you want to detect movement. The lamp head can be angled slightly away from this point if you need the light strongest somewhere else.
The fairly light solar collector is held to the wall with four screws. It may also prove too floppy on its universal joint and require a bit of fixing. Choose your location in the autumn/winter when you can see where the sunshine falls. The light itself is held to the wall with a small clip which attaches to a tiny plate with two screws.
NOTE- In the UK I very strongly recommend that you place a tiny roof over the lamp unit to keep the heavy rain well off, as it is really not water proof.
