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...

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. 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 the local market, this video is for you! Of the six "corn cob" style LED lamps tested...

Dead LED lamp autopsy.

A look at a modestly high powered LED lamp that was one of many that had failed. Also discussing various LED power supplies. The phosphor loaded gel in front of the chips seemed unusually tough and plasticky. I wonder if it had baked dry over time or had always been like that.

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!

Inside a very clever LED headlight lamp.

This started off as a simple autopsy of a faulty lamp and turned into something so much more. It's a very clever design that makes the circuit very universal.

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...

The High Pressure Sodium Light: Ubiquitous, effective, but good?

You can support this channel on Patreon! Link below Ever wonder why street lights are orange? For such a fast-paced world technology-wise, it seems somewhat odd that we are still using such a strange color of light for outdoor lighting. Well it turns out it is still a pretty good light source, though with limited use and perhaps a not-so-obvious flaw.

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 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...

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.


I'm not sure of the seller of this LED mislead me by telling me it was for UK 240V electric, but when I tigged on the solders it banged really loud. I do not recommend bying LEDs from bad people becauise they go boom and may scare you. And for those who actually read down to this level... The actual result of hooking a (really crappy) 100W LED directly across 240V was so boringly controlled that I had to beef it up a bit for a second take with hidden resistors underneath for some sparks and pops. See...

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.
