Item arrived in Malta after 3 weeks. The specs are overrated in that there is no way the battery will last 10 hours as implied.
When lit the LED draws just shy of 0.6 Amps. So since the unit comes with one 1200mah battery. it should stay on continuously for 2 hours at the most.
Arguably in most cases if you are putting a motion activated lamp its because you are not expecting so much traffic to start with, so the lamp might not be on for 2 hours a night and it might very well still have power just before dawn.
I noticed that the housing was designed to take 2 pieces 18650 batteries in parallel thus retaining the same voltage. So I have changed the original 1200Mah battery and put 2 pieces of 2600 Mah batteries. This in the hope that I will be covered for cloudy days. Now the weakest link is not the battery but the solar panel, which I am hoping will be able to keep the new batteries topped up.
The lamp is quite bright and I think that it is good value for money as it was originally and I do recommend it. But me I can't help fixing things which sometimes do not need fixing at all.

I have had this light installed for a few weeks now, and it has been exposed to rain on a few occasions. The light continues to work very well. The sensor is excellent easily sensing people from a minimum of 5m away. It is now summer for me, and the solar cells receive minimum of 8 hours of strong sunlight. The lights do not get used very much, so I'm not sure how the light will work in winter time when there is less sunlight for charging.

In the photos you will notice that the light has a rubber seal, and the solar panel does not have a seal. You can see for the light and the solar panel there is no evidence of water penetration, so I would say these are both waterproof. I have a photo of the screws and some have some surface rust, but still function ok.

You can also see from the photos how bright the light is. I don't think it is 600 lumans, but it lights up an areas 5m x 5m with no problem. It is adequate for my application.

The lithium battery is 3.7V. The specifications say the light is 30W. That means the battery will need to supply about 8 Amps. I don't think this type of battery can supply 8 Amps, so I don't believe the light is 30W. However, as the photos show it lights an area 5m x 5m no problem.

This is a great product, and I hope it lasts many years. I will see how well the plastic casing resists the UV sunlight.
