Large outdoor LED lamp and motion detector wiring question

I had a pair of pre-wired LED lamps on my garage that finally puked out after 3-4yrs (one remains in the photo) but have switched to a single 150w lamp that really kicks out the light. The sensor has a nice large sweep. ...but, mostly I like that it flashes three times before it stays on for the 5min I selected. It kicks butt when you walk into the beam at night. 'Throws a big glob of light. So far so good...

The issue: there is power to the lamp with the switch off; some LEDs are partially lit? I took my non-contact tester and see power in the cable near the lamp.

A) I know only enough to get-in-trouble. B) It seems color coded wiring changes at every county's border.

Still, it seems, simple enough: Red-Red ..three Whites ..Blk-Blk. ..even tho' the lamp uses Blue and Brown wires.

It's not the end of the world. I made it run for about 15min and checked the wiring with a non-contact thermometer to make sure I had not wired a 'toaster', but it is a puzzle I would like to solve.

Any suggestions would be appreciated. Thanks.

Jim

The brown and blue polarity won't cause an issue.

Does power go to the sensor first and then to the light ?
If there is three wire cable involved...... having an always live line combined with a switch line in one sheath can keep the lights dim or partially lit.

Thanks, PJ... Well ....three Whites connect together ... switch Red goes to fixture Black ... Black to house Black. ...at least that's how I have it written.

I do not have a clue about the difference between Neutral (white) and Hot (black). I gather it is some circular circuit ...but then I thought the lamp (or whatever) ate the current - and they send you a bill.

That sounds logical, PJ. I will rewire it. (once it cools off a bit) Thanks.
