Failed LED lamp Repair and improvements DIY Dubai lamp GU10 from Poundland.

- I decided to do an autopsy on a dead GU10 LED lamp. Lucky the repair was very simple. I also want to see if the lamp could be improved so that it would not fail prematurely again. It seems like they're designed NOT to last ( Planned obsolescence). Even though these LED bulbs are very cheap to buy, it doesn't mean they have to go into landfill. With a simple modification they will last much longer! In Dubai LED bulbs are required to last. So manufacturers for Dubai's LED bulbs are not allowed to build planned obsolescence into the products.

Brilliant. No pun intended. This was very well done. Nice work diagnosing the problem. So tired of these "forever" bulbs dying in less than a year. I like your motivation to reduce landfill. I hate throwing away working stuff.
Thank you very much for a great video. I have in the past just thrown these bulbs away as they're poopy cheap. Since, watching your video I have fixed dozens of them. Wooohoooo!!!!!
I'm glad you like the video. I'll be making more about different types of LED bulbs. Please share my video if you can, so more people can learn stuff together!
I got some failed GU10 Lamps too but no LED spare parts. The local Theater got a waste box with a lot of LED tubes 1,5m used for HF light tubes. Now I could also spend a lot of LED chips for your broken one.
Very nicely presented.
Thanks for the great video. I always wondered how these bulbs fail, and if they can be easily fixed. Thanks!
I watched a good tip by leaving the diffuser of which helps to keep the temperature of the led's lower.
My theory is why arcing kills LEDs is because they create lot of higher frequency noise that passes more easily thru capacitor.
And this one doesn't even have Alu substrate board it's so cheapened so it's easy to solder on, for me everything is easy to solder on because I use 100w soldering gun...
You are absolutely spot on! At 50Hz the capacitor dropper limits the current nicely. With the high frequency harmonics caused by arcing, you might as well have have a wire link instead of a capacitor!
Thank you for sharing your genius, again!
Very good, but for me, I think I would have bridged the duff led with a resistor? I liked your meter, very nice tool
All the LEDs are connected in series. So the increased current is very small, with the capative dropper circuit. I also changed the capacitor for a lower value. So the current was much reduced anyway😉.
Thank you sir. I'm a fan.
I had to repair a damaged led that I damaged opening up the bulb to check it out. it was fine before I opened it. I globbed on some solder.👍
Sweet job
In my one that was dead bridge rectifier and fusible resistor.
Was the live wire in your current limiting rig the one with the resistor on it? My electronics skill is basic, but I know that an LED only passes current one way and will be damaged if reversed.
I normally put a "old type light bulb" in series with the Live, for safety current limiting, to test small electronic circuits. But in reality doesn't matter if it goes on the live or on the neutral. The current for the entire circuit will be limited the same. And because it's AC there is no positive or negative.
Thanks, I thought the light bulb must have a rectifier to convert AC to DC, but as I say my knowledge is basic. Thanks for your help the video is really inspiring.
@@CackHandedDaveDoesDIY yes all LED bulbs have a built-in bridge rectifier, to convert the AC back to DC. When powering individual bare LEDs you need a DC low voltage supply, with a current limiting, in the form of a resistor. The LEDs only light up in one polarity, so reverse the polarity to check both ways.
One bulb all but one led on the end was good. Another bulb all led was good but barely dim flicker lit when in socket. Need to know how to test components but probably not worth repairing.
I tried to repair but it's dim what can I do
My led bulbs are blinking. How to rectify them.
Sateesh.
Hi, found your video After one of my gu10 from Philips hue failed After only 2 weeks and it is not a cheap one and I don't know why :( Any Idea what could have been the problem ? Thx
It could be different things. The gu10 in this video has a simple capacitor dropper, driver circuit. That style of driver in not very common nowadays. If its a smart bulb, then it could be the driver/power supply that is faulty.
@@MyProjectBoxChannel Thank you for the above. Do you think it could be repaired ?
@@theattorney6072 mabe it could be possible but with out seeing it first hand, I couldn't tell you.
Typical high failure rate Chinese manufacturing !
