I quite like the current range of LED globes from Poundland and thought it would be quite interesting to see what sort of effect changing the dropper capacitors to different values would have.
The results were interesting, both in regards to the temperature to power ratio and the impressive amount of light the lamps can put out when run at just half a watt.

Do not remove that 100K resistor is to protect the circuit from high voltage and to burn the fuse before the led circuit get burned when the capacitor fail or get shorted also by kirchof law the 100k resistor is in parallel with leds and the resistance for that is not 100k anymore but need more calculations and that resistor acts like a voltage current shunt is like a MOV surge protector 😊

There were LEDs when you were young?????….chuckle
Hi, do you think it's possible to under-volt an LED bulb like this? I'm trying to find a low wattage bulb I can run of 75vac.
•_•)/ Thanks for the values..
I hack a Warm LED using 33nF Capacitor and it seems to be enough for my sleeping lamp…
🤔 It show 0.0w on the meter.. A free energy
I bought 2 sets of LEDs for use on 240V here in Canada….i got the 12 Watt range for a desk lamp. Out of curiosity, i tried the Phillips one (non multi voltage model) on 120V and it works …. at abt 9 or so watts (looks like a 75watt bulb vs the intended 100W on 240v). I then tried the cheapo no name brand one(also a 240V rated led bulb) on 120v but it didnt work. Why would that be? ….Would running the Phillips one on 120V also increase the life of the bulb….without mods ? Do you ever tear open a name brand LED bulb or are u a fan of no name ones ? 😆 Ive tried no name cheapo local bulbs and sometimes i find the CRI is a little off … not as pleasant 2700K as the branded ones. So it ends up being outside for my driveway 🤣
Good stuff indeed Clive, have you considered measuring the luminosity of the bulbs so that a factual value can then be compared?
Thanks Clive

Clive what bulbs do you buy ? all my corn cob LEDs are blowing up !
Wow. One of my LED bulbs has started a slight flicker; it does it every once in a while. Rated for 9 watts and 800 lumens. Branded Maxlite.
Have you taken apart a 12W globe yet? And how many LEDs are there other than those 10LEDs could see, where does the rest of the voltage gets taken up? Btw, what is the voltage drop per LED?
Have you done a tear Dow not of a balance board I would love to see one done
Which component would fail first? Smart money's on the electrolytic capacitor.
