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.
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.

People wanting a big light for their car: light bars exist now, cheaply and reliably http://amzn.to/2noXgNe Here's that neat 1150 lumen light: http://amzn.to/2xwQEUO FAQ's!!! Q: why are you only turning it on for short bursts? A: The reason is just that I only had one night with the camera guy to get all the shots and I was paranoid of losing battery.

A: No, it can run off a power supply continuously with a stable coolant temperature. Q: How long does the...

Dual Beam LED vs. Halogen in Reflector Headlights

In this video, I compare dual-beam LED to halogen bulbs in the reflector headlights on a 2012 Hyundai Tucson. This is the first time I'm testing a dual beam LED (high and low beam in one bulb). I perform a side-to-side test of brightness, coverage and temperature of these two bulbs in both low beam and high beam settings.

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...

The Potential Dangers of LED Lights | quick tip 9

There is considerable evidence that LED lighting poses some potential health detriments, especially to eye health and the prevention of macular degeneration. Incandescent bulbs give off light near the infrared end of the spectrum and this aids in repair and recovery of tissues, while the LED bulbs give off blue light which as been found to cause degradation and ROS of the tissues. Avoiding LED lights is less of an issue in a sun filled room but much more important after sunset as blue light before bed decreases melatonin production.

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...

Ebay LED floodlight scam warning.

If you've bought or are considering buying an LED floodlight from ebay, then this video will show you some of the pitfalls. From unconnected ground wires to MUCH less than half the quoted power rating. I'm not sure why it's so common to see the earth wires left unconnected. The fixture is mains voltage and metal, so it should be earthed, especially when the cable has an earth conductor in it. Although the LED operates at a reduced voltage, there is still the potential for water ingress, electronic failure or bad manufacturing that could result in the casing...
