Analysis and flame test on a PIR ceiling light.
Added 2019-06-24 01:09:55 +0000 UTCThis light was sent for our exploration by Miek in Florida. It's a very common eBay ceiling light with PIR sensor and it appears that the same style of light is also being sold in the UK by a prominent seller, albeit with different internals.

It works, but the yellow wire is definitely not an earth wire.

The trouble is that none of you have been to a chinese school..... They all sing the morning song together without fail. I think it goes something like this.......... He who would valiant be, ′Gainst all disaster, Let him in ohms to be, Follow the master. There’s no discouragement Shall make him touch the red. His first avowed intent... To be an earth rod ! ! !
2019-06-28 22:20:37 +0000 UTCre the turning on and off as soon as it is given power, I have a Philips dusk/dawn bulb which does the same thing https://www.philips.ie/c-p/8718696739402/led-bulb Assumed that as the light itself was so close to the light sensor that it was the light trying to detect real ambient light levels vs the light being emitted by the bulb itself (if that makes sense). Notably it does not exhibit the same behavior during normal daylight, just from dusk onward.

2019-06-24 11:02:36 +0000 UTCIs it odd that the thing I noticed the most is the HOPI stopped strobing when the light washed out the camera view?
