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.

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...

Inside a smart meter, and the REAL problem with them.

A look at the insides of a modern smart meter with wireless modem. This meter was found amongst a pile of fly-tipped building materials. The company named on it was contacted but failed to respond, so that means we can take it to bits. I've covered the serial number as I usually do with shady things, to avoid the wrath of angry midgets. While I'm inside I also investigate the conspiracy theories about:- Government spy microphones. (Like Alexa for instance.) Chemtrail brain control chemicals. Spy cameras. Brain irradiating 5G death waves. The ability of the meter to be programmed to read apparent...

Awesome flesh-burning death lamp. (Germicidal UV)

Another sensational eBay delight that you should probably not buy unless you really know what it is and does. It bathes a whole room in the icy glow of UVC narrow band ultraviolet, which can cause eye and skin damage to anyone in its vicinity. It appears that the "acarien" reference may be to do with killing dust mites. I'm not sure how effective that is, but it definitely puts out a lot of UV and makes the room smell strongly of ozone in the process. UVC tubes are often used in industrial food processing equipment to sterilise...

Water Cooled 72,000 Lumen LED Flashlight!!

People wanting a big light for their car: light bars exist now, cheaply and reliably Here's that neat 1150 lumen light: 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. The other reason is that it's so bright that it's annoying and I loose the ability to see at night Q:Will it eventually overheat? A: No, it can run off a power supply continuously with a stable coolant temperature. Q: How long does the...

In-Glass Fingerprint Reader TEARDOWN! - How does it work?!

In my previous Vivo X20 Plus UD video we did a durability test on the Under glass fingerprint scanner from Synaptics. In this video we will teardown the In-glass fingerprint scanner to see how it works, and what the sensor inside really looks like. PLUS we get to set the sensor side by side with the main camera sensor from an LG V30 to see the color differences. Pretty awesome technology and the only place to see it first hand *From the INSIDE* is here on Jerry Rig Everything.

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). Comments mentioning China Export will be marked as spam automatically, because it's horseshit. Commenters trying to use alternative characters to bypass the spam filter get muted from the entire channel. Based on feedback comments on my earlier video and a request from the folks at, 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...

Inside a very clever LED headlight lamp.

Poundland 6W LED lamp teardown with schematic.

More camera tests and a very retro sound with a device microphone that removes most of the pesky bass from my voice like the iPad used to. It seems fitting that I should take apart a lamp to continue the retro theme. I realise that some people like the bass, but for many others it causes problems with compact playback devices with small speakers that end up very quiet because they don't have the frequency response to match. Other notable things are that this device is tricky to get a decent light level range on. That also matches 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. Find these bulbs on Amazon - LED dust caps - To see all JDM ASTAR products, go to Support my channel and buy my shirt!
