CHEAP vs. EXPENSIVE: LED Pod Lights (Unboxing)

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!

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.

The shocking truth about cheap LED "corn cob" lamps

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...

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. You can...

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.

Driverless 50W LED teardown and schematic.

A complete teardown of one of the new driverless LEDs. It's interesting that these devices seem to be based on the chips used in some LED filament lamps. They seem to share a common array of LEDs, but have a number of driver chips bussed in parallel according to the power rating.
