At £5, this is worth getting for the parts. It has lots of potential for being hacked for powering with USB (with series resistance) or a solar garden light module.
The lamp itself has four filaments with 15 LED chips in each, so a total of 60 LEDs in parallel that start lighting at around 2.4V, and pass 100mA at around 2.7V. That's a decent brightness, so the use of a USB cable with two 10 ohm resistors would make this a very useful off-grid ornamental light.
Running the lamp at that low current will also give it a very long lifespan.
At a full 3V the current increases to 450mA (about 1.5W) so on fresh alkaline cells or freshly charged NiMh cells this will put out quite a lot of light.
The ceramic base with glued-in threaded insert means it could also be retrofitted with other low power and low voltage bulbs for variety.

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

It's another Poundland delight and actually quite a nice one this time. It's a standard sort of filament style lamp, but it just takes two double A cells and when you turn it on, it's not bad. It puts out a good amount of light, even on nickel metal hydride cells, which is what I'm using it on at the moment and it's actually just an attractive lamp. So this is our heavy ceramic base and initially it looks as though you can unscrew the lamp and you can unscrew that, but it's not recommended.
I've already broken it and had to repair it, but this is good because in doing so, I've opened the thing up and we can see inside. Let's take these air. Power Cell Uh, rechargeable nickel metal hydrate cells out and if I pulled the base out, is this going to come out? Is it going to come out? I may have to screwdriver this out. Let's get under here and price it because I think the hot milk is kind of like sealed up again.
all it has. It's really sealed in tightly so it's a ceramic base with the battery compartment and inside. Much to the horror when I unscrewed it is basically it. It is most of a screen base except that when you're actually trans screen it, it does rip the wire off.
So let's have another go at this and see if I can just wreck again. So there's a little silicone o-ring here, a big Splat of hot milk glue there. One wire is sewed onto the side and what they've done is they've left off the Little Pip So let me just get a pair of Cutters and just Lop this off and that There we go. So now we have almost a three volt lamp, but all we need is the little pin that goes in the end that makes the connection.
They're fairly standard. you can remove it from another holder and it is just a freaking fit pin that uh, goes onto that wire. But in this instance, instead of actually putting that in and Soldier onto it partially because it mounted the plastic, they've brought the wire out completely and soldered onto it. That was quite hard to solder onto because of the type of metal it is.
But no, we have the possibility of either keeping this intact, modifying it. you could power off USB You could add a couple of 10 Ohm resistors one in each leg just for the convenience of that, and you could actually have this illuminated from either a USB power supply continually or a power bank. Because you know, just because there's an apocalypse doesn't mean you can't have pretty lighting around the home. So that's it.
It's a nice little thing, you know it's attractive. Um, and it works very well. and it's quite good to. these must be parallel array filaments.
to be honestly, three volts with parallel LEDs in each and they're all hooked in parallel inside, so it's quite neat. It's actually worth getting just for the lamp if you remove it very, very carefully, but you also do have the option then of actually having this heavy ceramic base with the battery pack to power it just as an ambient table ornament with no Mains Power required. Quite nice. I Like it. .
I found one of these in 2021 at a discount food store called Grocery Outlet in the USA, it ran on three AAA's and had a concrete base ! I have hung onto it ever since really which I could have gabbed more of them ! mine however has a full base that unscrews with a warming label on it not to put in in a normal light socket, my guess is thats why it was in the discount shop.
This product further bolsters my theory that there is a network of factory managers in China who work together to find uses for their surplus inventory.
would a 18650 be to big for it, might get one for me Tramper van 🙂
A little solar circuit from a poundland solar lamp to power it as a night light perhaps?
I just bought something similar in the German discount chain Penny for 10€. They have the same style of bulb plus a longer thinner one. The base is made of concrete instead of ceramic, it is powered by a nonremovable 600mAh Liion battery, and rechargeable through USB-C. Also it's got a 24h timer mode.
thats goign to eat those batteries quite quickly and will go dim quite suddenly , those draw a lot of amps, especially with no resistor – and no circuit to drive LED properly
"Just because it's an apocalypse doesn't mean you shouldn't have pretty things around the home"
That is fabulous. Might I steal this line?
Thank you. Keep working, good luck.
Cool bulb 💡

I wanna see what happens if you screw it into a standard mains lamp socket.

Not sure why I'm still not getting your notifications. And already had to resubscribe more than once.
But i just wanted to let you know, that heavy base is totally safe.
Depleted Uranium is fairly safe. I probably wouldn't use it as my bedstand light though.
You may not need the light itself after a while 😂
… just giving that product a Glowing Review
just was browsing on conrad and found that they sell your CLIFF quicktester.
with or without wire going in .. but quite expensive

(Maybe youtube bots wont autoblock this post as they normally do)
Item no.: 103857 / Manufacturer no.: CL1860 with EU Schuko Plug almost 80 eurobucks
Item no.: 103856 / Manufacturer no.: CL1850 for no wire and 60 eurobucks
How radioactive is that heavy base?
I would like to try installing a joule thief. I have made some that can light up a single 5mm led for weeks on a dead battery and up to a month on a fresh battery. Would love to have a "forever" glowing LED lamp.
I wish some of the stuff you show was available on my side of the pond.
just as well it did not have a full es fitting , some one some where would have unscrewed it and replaced it in a mains es fitting !!
