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.

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.

Unboxing a $500 LED...

In this video I take a look at one seriously interesting LED. Check it out here:

CHEAP vs. EXPENSIVE: LED Pod Lights (Unboxing)

Most expensive LED lights: Middle of the road LED lights: Cheapest LED lights: 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!

Cree LED Bulb teardown

Yet another LED bulb teardown. This is a inexpensive CREE branded LED bulb. I'm getting used to editing videos in Adobe Premiere. It's definitely nicer then Windows Live Movie Maker.

Why some LED bulbs glow or flash when turned off

I've noticed that a few LED bulbs continue to glow slightly, flicker or flash even though the power switch is off. This video explains why this happens.

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.

Free Copper - Copper Bar from a Microwave Oven

Getting free copper is easy, Just find an old microwave oven. Scrap copper is getting harder to find without the old tv's around, but microwaves are everywhere. I recommend this Furnace.. (Affiliate) It uses Propane Gas which is much cheaper to run with no problems like burning out the element and gives you better options for crucibles like stainless steal or cast iron which last a long time. Watch more of my melting videos.. Check out my recommended safety products, Furnaces & stuff on amazon.. Pouring copper ingots is my hobby, I have sold a few on ebay at 6x the scrap copper...
