Problems with floodlight

Hi, the floodlight (with a replaceable halogen lamp/bulb & PIR sensor) in my garden had stopped working.

Now, the flexi power cables which connects to the back of the floodlight comes out of a hole in the wall. The 2 power cables are taped together & each cable is wrapped in a rubber coating and each cable has 3 wires - green & yellow, brown, blue - which stick out at the end. All 6 wires were connected to the old floodlight which recently stopped working.

I purchased a first replacement floodlight (with a replaceable halogen lamp and PIR sensor). The connection points in the back of the first replacement floodlight had only points/connections for 3 wires - 1 green & yellow, 1 brown, 1 blue - but not for all 6 in my power cables. I connected 3 (green & yellow, brown, and blue) of the 6 wires. When I switched it on for the first time during the day, the light went on. A few hours later, during the dark, the light would not go on at all. I opened the connection box at the back of the replacement floodlight, to check the wires and their connections. All ok. When I switched on the light, it flashed for a second but that was it. I switched it off and on several times and each time it flashed for just a second. I returned it.

I then purchased a second replacement floodlight (with a replaceable halogen lamp and PIR sensor). Again, the connection points in the back of this replacement floodlight had only points/connections for 3 wires but not for all 6 in my power cables. I connected 3 of the 6 wires. It worked for the first night. On the second night, when I switched it off via the light switch on the wall, the sensor continued to detect movement & the light stayed on for some minutes before turning off, & even then the light went on more than once when it detected movement. How can this be if it is switched off via the light switch on the wall? I then disconnected the cable and I connected the other cable but the light would not come on at all. I returned it.

I then purchased a third replacement floodlight (with an integrated LED lamp and no PIR sensor). Again, the connection points in the back of this replacement floodlight had only points/connections for 3 wires but not for all 6 in my power cables. Anyway I connected 3 of the 6 wires. The light came on but it stayed on even when switched off via the light switch on the wall. I then disconnected the cable & I connected the other cable but the light would not come on at all.

I also noted that one switch on our mains box was sticking down & the electricity & lights in the outhouse would not go on. When I shifted this switch back upwards, the electricity & lights in the outhouse returned. I wander if my attempts to replace the floodlight and the temporary loss of electricity and lights in the outhouse are related.

This is driving me crazy. Please can someone advise me. Thanks.

I can advise you... call an electrician as you have gone through 3 different light fittings and it is now worse than ever. No harm in having a go, but, I think with all due respect to yourself you have gone as far as you can with this with the knowledge you have.
