Inside an "intelligent" emergency lamp (with schematic).

Although I've featured this style of lamp in the past I've never done a full reverse engineer of the most common type. So here it is. It's one of those products that achieves economy through clever tricks that take a moment to get your head around.

Here's a generic link to find eBay listings for these, noting that some sellers are using the same keywords for ordinary LED lamps. So look for listings where they show someone bridging the cap with their fingers or with the screw-on switch cap to use it as a rechargeable work light.

Aim for a target price of around $3-4. Note that some may be for universal voltage and others may be intended for around 220V only.

The reference to another video on Patreon that was not released for general viewing relates to the device this is out of. A commercial emergency light sold from a prominent UK supplier. The company involved reacted immediately and had the product pulled from sale, and their supplier is now doing a recall on it. I've not released it for general viewing to allow a controlled recall. Any Patreon supporters who have not seen the video can still see it on that site.

If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
