[What movement sensor and led floodlight wattage for 10m height?]

It would be a lot better to install the equipment on the outer wall of the stairwell at 2 - 3m height, PIR should then have no problems working and your 200watt flood will actually be able to give a reasonable amount of illumination.

Personally, as others have said. I don't think a PIR at 10m vertical height is going to work. And your flood is more than likely going to look like a Glow worm.

Who does the existing carpark lighting belong to ?.

Google Street view images are from 2012, so quite old. Recently the exterior of the building has been renovated and thermal insulation installed, so it looks like this now:

The issue is that most residents don't mind the installation as long as they don't have to pay for it, thus I am footing the bill for the equipment and the electricity will be shared between the car owners.

I might be able to install the RIP at the entrance, but that means 2x 10m cables running down to the sensor and then up again to the floodlight, which is doable I guess.

Existing car park lights belong to the city and they certainly don't work if they are even there.

You would need multiple PIR's to cover that area. I imagine that cheap light will die quickly.

Do the street lights in the centre of the car park not work?

I would say bulkhead type fittings with motion on each side of the porches would be suited better.

I don't need to cover the entire area, just around the right block entrance, so half side of the block. So like 10x10m area max.

If the landlord has control of the existing lighting and it works, the simplest upgrade would be to remove the existing lights and fit a Unistrut arm to each pole. 2 decent LED floods on each arm & angled accordingly should give plenty of lighting.

Each apartment has its own owner/landlord. There is no central authority here. People are poor, nobody wants to spend any money. I have already purchased the flood light and will be doing this myself with the help of a few other owners. There are 3 apartments per floor, so 45 in total for the right entrance.

What supply voltage does this "Country" operate on ?

Same as UK: 230V

It's for a flat I own in Bulgaria.

Here is a view towards the mounting position, 4th floor roughly 10m height: https://goo.gl/maps/trd8ABzG7xrDMPJ78

I have spoken with a few neighbours + the block manager and they are all happy with the idea as it is for the benefit of the entire block.

When people are coming home at night or there is someone in the parking lot the light needs to activate.

I am paying for everything, so trying to keep costs down.

Managed to get this LED floodlight for £25: https://www.amazon.co.uk/gp/product/B01LWKC0G0/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

What further information is needed to understand the full picture?

I doubt you will find and all in one unit that would do something that.

Before you even consider anything I would contact the landlord and explain that you feel the need for better lighting in the area.

It's not your responsibility to be adjusting the electrics in a flat

I am not looking for an all in one unit, but separate. 

I have permission to install it, it is not in the UK.

Agreed and thatounting height is outside of any pir I know specs

But height is a relative term. If we vusually rotate the block of flats 90 degrees then its face will be the ground and so installation will be at ground level. And the parking lot will be like the opposite wall 10m away. If I adjust the mounting angle of the sensor would it work? Most cheap sensors have a max distance of 12m.

I live in a block of flats on the 4th floor and want to install a LED floodlight triggered by a narrow angle movement sensor.

There is a parking lot in front of the block and the installation height is around 10m.

Can you recommend a movement sensor to detect people walking downstairs but not across the entire parking lot.

Also what floodlight wattage would be sufficient for 10m height? There are 100,200,400,500,800,1000W on Amazon.

Thank you.
