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!

Video description
These are LED bulbs number 3 and 4 in my failed LED bulb teardown series. Initially one of the bulbs would light normally for two seconds and then go out (first one checked). Watch and find out what failed inside the bulb.
Ebay $1.50 Filament LED lightbulb teardown (2W)

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.

Philips LED Lamp 9.5W Teardown

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.

LED Light Bulb Frequency Effects on the Human Body

LED light bulbs are quite different from conventional filament light bulbs. We test a typical LED light bulb for the effects on the human body frequencies. Excessive EMI/EMR emissions may lead to radio wave sickness (RWS) and/or electromagnetic hypersensitivity (EHS).

Dollar Tree $1 LEDlife 6.5 watt LED Bulb review and teardown (40 watt equiv)

See my other Dollar Tree LED bulb teardowns here: @bigclive always finds cool LED bulbs at Poundland in the UK an I finally found something similar in the US at Dollartreet in Portland. 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.

Test and analysis of unusual (dead) LED lamp.

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.

GE LED Bright Stik bulbs at Home Depot

New at Home Depot, $9.99 for a pack of three here in Portland. 10 watts claimed, 760 lumens, 2700k soft white. In my Kill-a-watt I am measuring 9 watts, 120ma. 0.59 pf so no correction. (The Philips Slim Style has a 0.93pf so they make some attempt...) These are slim and built down to a cost, but what is nice is that since they are so slim is they work in fridges that call for an Appliance bulb. This alone is fantastic as I have never found a 60 watt LED that could do that.

3W, 5W, 7W, 9W same-range LED lamp teardown.

I saw these lamps being sold on ebay and decided to get one of each to compare them internally and externally. They use standard capacitive dropper circuitry (Even the 9W one!) and I have to say that they're all pretty neat. They rely on a very well ventilated structure for cooling, although this is slightly defeated by the closed front. The PCBs themselves are covered in airflow holes and the housing has a lot of ventilation slots that actually make it very stylish looking.
