I enjoy electronics, building DIY projects and repairing things. Most videos will be electronics related, but I will toss in something random here or there. Enjoy!
NOTE: CE does NOT mean China Export, it's just a mis-spaced CE logo (just like the one on the back of an Xbox 360). https://en.wikipedia.org/wiki/CE_marking#China_Export Comments mentioning China Export will be marked as spam automatically, because it's horseshit. Based on feedback comments on my earlier video and a request from the folks at http://www.avforums.com/, this is a shorter test on a range of "corn cob" LED lamps available on eBay and Amazon. If you're thinking of buying cheap LED lamps, whether it be online or from the local market, this video is for you! Of the six "corn cob" style LED lamps tested...
A Philips LED Lamp which stopped working is dismantled to see what is inside. 9.5W, 220-240V. Warm white 2700K. The LEDs are 24 individual surface mount items arranged in series. These still work, the failure is in the power supply which unfortunately is potted in resin. Case is made from thick metal with a plastic coating over it. This was purchased in 2013, and has been used for 6-7 hours a day, probably about 5000 hours in total.
Review and teardown of the latest Dollar Tree $1 Greenlite LED bulb. This bulb is dimmable, uses less than 9 watts and produces 800 lumens. It is also approved to use in an enclosed fixtures as well!

Why are LEDs so much more efficient than incandescent light bulbs? Do LEDs have disadvantages? These are some of the questions I answer in this video about light bulbs. I also test the claimed wattage and find some anomalies...

Teardown of a filament LED lightbulb from Ebay for $1.50 including shipping. Rated 220V 50Hz, the nominal power is 2W, real power is cca 1.6W, it has a E14 screw base. It is quite bright and looks nice, but there's no fuse in it. There's also no filter capacitor, so it has a lot of 100Hz flicker (not visible to the human eye unless you move it fast). It has a capacitor dropper in it with a 330nF capacitor, 1M discharge resistor and 1k inrush resistor. The 330nF multi layer ceramic capacitor looks quite small for the mains voltage. You can...

The thing that makes this LED lamp odd is that the current regulation is physically built into one of the LEDs. Given that the lamp was running at around 9W of power it's almost inevitable that one of the LEDs or its bond failed on each circuit.
This started off as a simple autopsy of a faulty lamp and turned into something so much more. It's a very clever design that makes the circuit very universal.

Most expensive LED lights: http://amzn.to/2D52IMt Middle of the road LED lights: http://amzn.to/2l1slXg Cheapest LED lights: http://amzn.to/2kM66W8 As we upgrade our LED lighting for our backhoe, we wanted to see for ourselves if there was a difference in LED lights at various price points. Were expensive LEDs worth the money for such a critical tool on our property, or should we stick with cheap LED lights made in China? We hope to torture test these lights, but for now, enjoy this unboxing where we share our immediate observations. ENJOY THIS VIDEO? SUPPORT US WITHOUT PAYING A DIME!

A $1 light bulb which comes out to 66 pence! Whoa! Anyway, I took it apart and as you can see here it's not a piece of crap at all. A very nice 40 watt LED bulb.

I purchased an 8W LED Filament bulb on eBay, and after a week of use (~50 hours) it experienced a very unusual failure. One of the LED filaments "shattered", perhaps due to overheating or power surge, explanations would be well appreciated but I've never seen this failure before. It's a 230V bulb and had a noticeable flicker when it ran meaning it probably uses a capacitive dropper power supply (as seen with similar LED filament bulbs).
