A full autopsy of a generic plug-in nightlight. I was kinda expecting it to have a little capacitive dropper inside, but it has a minimalist half-wave resistive dropper and the light sensor is basically a transistor shunting the LEDs during the day!
It works, so I guess that's what matters. And even with it's less than efficient design, it probably draws less overall than the older tungsten style.

just ordered 2 of these close to them different brand prob same build lol and u know im watch your video on them !00% thanks for sharing
Bought some of those but the light don't turn on no more after a couple months of use. No switch button. Its sensor light. Didn't know you have to open them
How does it turn on though? I plugged them in all my sockets and they didnโt turn on.
Wouldnโt the resistors only be dissipating 1/2 watt since they are two 12k in series? Each is only dropping 120V.
I was disappointed to find that mine, just like yours, draws more current when off. They deceive the consumer by making him believe he's saving $$ when the LEDs are off! Nasty! So I removed the CdS photocell and it now stays lit 24/7 but draws less power. This is typical of cheap nasty Wal-Mart merchandise.

i have one color LED plugin nite lite

pretty nice plug in night light with LED on this video…
how come america dont like to makeing their own plug in night light with LED
What is the transistor value?
I've just watched a clip with John Ward tearing down an identical (or near identical) one. His live and neutral pins were twisted but was much cheapness at 99p.
I know this is OLD, but how would you fix this night light circuit?
Bugger me! You've saved my sanity with this 'how to'.
Just bought the same light from Home Bargains for ยฃ1.50, and the instructions said nothing about removing the lower 2 screws, only the upper 1 – leaving me scratching my head and angrily pulling at the unit – which appeared to a simple, slide-off cage which wouldn't slide off. Now I don't have to take it back in order to learn how to change the bulb. (Mine's an incandescent, by the way, and gets quite hot within a few mins.) Thanks!
I bought one yesterday and it as a small bulb and no LEDs at all, seems the tungsten is back in fashion, also no flickering or shimmering actually it as a nice orange glow.
This light sensor design was clearly meant to be used with a capacitive dropper instead of a resistive one.
