That wasn't bad really. Though as a rule I do tend to seek out and remove lots of screws. It's quite frustrating though when you are looking for a screw or a clip or something and I'm sat here shouting "ITS BEHIND THE THINGY". In my news, whilst watching this, I managed to embed the top of the SMPSU chip in the amp I am working on into my ceiling. This is because one of the aforementioned stray screws ended up stuck between the pins of another component, most likely the resistor and capacitor that I haven't found yet.

It didn't hurt until i pulled the bastard out and that's when i found out that you have a pulse at the end of your thumb as blood spurted in rather large quantities all over the place.

I wanted to go back to 40% of the rated power and the lamp started flashing. 60% was the limit. I bought a bunch of 10 ohm pots which I put in series with the existing current limit resistors. Makes life much easier. Cheers 👍🤝🇳🇱

I had a similar experience yesterday. I wanted to dim down a 15W ceiling lamp. It has a SIC9554A which is the same chip as the BP one but from Shenzhen SI Semiconductors. As the sense resistor it had 5.6R in parallel to 1R. I just removed the 1R which should have given me roughly 2.7W output. But the lamp did not light up, when plugged in. Instead it gave a brief bright flash every time I unplugged it. With the 1R back in place it worked as before again. My assumption is that the LED short protection kicked in. I will try it tomorrow with a lower value sense resistor. So there seems to be a lower limit to the power you can set. EDIT: I just had another look at the datasheet and noticed that Radj for the OVP is also dependent on the Rsense. so, when I sixfold the Rsense I should have divided the Radj by 6 as well

The thickness of the blade is often essential in liberating the globe from the adhesive holding it to the base. That's a delicious pi filter in the power supply. Pity the rest of the lamp wasn't so well ingineered.

I was once levering a very hard plastic case apart with a screwdriver (IIRC) and the case shattered. I still have the 1.25 inch scar on my thumb where the plastic acted as a makeshift scalpel. It compliments nicely the star shaped scar from a flying molten solder ball from tapping the soldering iron on the table to clean the tip.

A suggestion Clive. Although you may already do it. When replacing screws into existing holes, particularly of the self tapping variety into plastic, it's worth turning anticlockwise first and you often feel the thread click as it lines up the start of the screw thread with that of the thread in the plastic. It means that you're not cutting a new thread but following the existing thread.

A good short flat screwdriver, slightly sharp and 4-5mm wide, opens everything that requires excessive polite negotiations. Going around to loosen the sealant and then a deeper insertion...to puncture the sealant, and tear the cover over that spot by hand. I've been recycling my dead(preferably dying) bulbs in the recent years, saved a bit for my pocket and alot to the dumpster. Tip - if a bulb flickers it's obviously about to go, if you catch it in that period (seconds to days) - the needed repair is a dry cap, a 5 minutes job for a 3$ bulb. If the bulb has already gone RIP, then the bad cap shorted through the LEDs, if only a few had been fried - chip them off and bridge them inside. Another tip (yes, I have no life😅) - changing the current sensing resistor to slightly limit the current, extends the bulb's life. *Those driver circuits are set to-and-even over the rated limits of the LEDs and the electrolytic caps, otherwise those bulbs could last a few years easily.

Have one of these, picked it up for about £5 on offer. Always wondered what was inside but with it working and me actually using it did not want to risk busting it. Mines been going strong a few years now, its not as bright as i thought it would be when buying. I got it because i have a large room and only 1 small light fitting in the middle. Figured it would spread the light further (kinda does).

I had similar problem with some buck regulated LED lamps, they did not like replacig resistors to anything higher value than standard, sometimes they flashed, other times they did not work at all.

That aluminum plate is the same type of construction that I've always encountered here in the US, from the very same big chain that you mentioned. I ultimately ended up taking some heavy shears to the plate because I couldn't break the adhesive holding it to the lamp shell.

It's mostly heat. The efficiency of power to light conversion is still relatively low, even with LEDs.

A theoretically perfect visible white light source emits 251 lumens per Watt. An LED bulb emits about 800 lm for 12W, so if it was a "perfect" radiator 3.19W would be emitted as light, and 8.81W would be heat for an efficiency of 26.5%. Real LED bulbs are not "perfect" white light radiators, so it's even worse than this. As a comparison, a "perfect" 60W tungsten bulb would emit 56.81W as heat for 3.19W as light for an efficiency of about 5%. But tungsten bulbs are even farther from perfect white light emitters, so they are far worse.

It's interesting to me why the globe part of the lamps are glued on so tightly. I opened my own LED lamp and a significant amount of that siliconey-type glue was used. Didn't make sense though, since it just snapped right back on after scraping it off like there is a ridge to securely hold it in. My guess is as good as yours, only being that it's to stop the globe from turning when inserting/removing it from a fixture.

They're glued on tightly because live mains is exposed on the circuit board, and they don't want to be sued and be forced to put a warning sticker on the thing.

Hey Clive. I've enjoyed your LED light videos lately. I can't help but think you have discovered remnants from the planned obsolescence incorporated into light bulbs by the Phoebus cartel. It's very interesting to watch you, perhaps unknowingly (?), call out these hacks that can modify performance of these goods to the optimum efficiency and longest life they can handle. This thought had only occured to me while I was watching another KZbinr discuss planned obsolescence and how it elvoved from the light bulb industry. I'd like to know if you knew of this, as I think E waste is a big deal now for the earth and it's environments. Especially nower days when we have the technology to prolong the life cycle of electronic goods, such as LED lights, that we can erase a lot of the waste created by these products. You have made me see the electronical industry, as broad as it is, so differently. It's amazing! You have a real thing going, bubbling under the surface of these videos that could spread and empower a good change for technology. It's just the greed of businesses and labour pirates that keep people buying over and over, even if it is just a bulb from the pound store. Thank you for this perspective
