- I've always incorporated flashlights in my lighting arsenal. And with LED lights getting more powerful, you now can light people and make it look professional. All you need is a few gadgets and some imagination.
Any flashlights that you guys recommend ??? I'm always on the lookout for new ones!!!

That's pretty interesting. Never expected flashlights would be this handy in films
At 4:55, the artifact you're referring to is caused by the Pulse Width Modulation on the LED. Some LED products use PWM to control the brightness of the light--it's basically strobing the light at a rate that is faster than the human eye can detect in order to reduce the amount of time that the LED is illuminated, saving battery. Sort of how a fluorescent light strobes at 60hz, causing noise if your shutter speed isn't synced, except PWM is a much faster pulse--it causes interference with the camera's shutter speed at almost any shutter setting. You'll generally find this in LED lights that can dim, since it's an easy way to control brightness in an LED light.
Thanks Blaise Douros , knew there was a technical term, just didn't know what it was called. Thanks for clarifying !!!
Blaise Douros Exactly right. It's the same type of artifact you will find when shooting NTSC mode in countries that use 50hz electricity
Really shows that you can get great quality from cheap flashlights and inexpensive products. Thanks for sharing this
Especially b/c most portable video lights are LED anyways, these flashlights have pretty much the same kind of bulbs and put out the same kind of light. It's a no-brainer !! Lakeside Productions
Too True
It's amazing that with the democratization of low light cameras, these lights are a actual solution. Certainly having a small portable and affordable kit has huge advantages when on a budget. Keep being creative so we can all tell better stories.
Well said Drew Hewitt , if there are any episodes u want us to make , let u know.
Congrats for your creativity!!!
I've been thinking about doing this, thanks for making the video!
5:22 holy **** someone is behind you!!
the strobe effect is usually an effect created by two un synchronized digital devices. The flashlight just as a screen is the emitter, and the camera the receiver. If the emitter turns on and of (strobe, which as far as i know every screen does, and some flashlights) at a certain amounts per second, usually faster than our eyes can perceive. And so does the camera take picture frames per second, but often at a slightly different frame rate. This causes the wave effect, that you only experience through a camera.
So great. Thank you!
Dude, I just discovered your channel and you're brilliant! As a photographer I'm always experimenting and this is just pure inspiration! Keep up the stellar work!
Thanks for the kind words Shawn. Also I think I increased the value of that Kobalt flashlight. They don't make them anymore and they cost like $150 on Ebay.
Kickass work, thank you!
That mannequin behind you scene could've been amazing if you could after effect like one blink and devilish smile on it :D
Great video, thanks!
THANKS FOR THE UPLOAD !!!
Thanks for the video. I've always been put off lighting since the prices for these damn lights are more expensive than they should be. THis is definatley a thing I'll try out.
That was a great episode.
Thanks Bryan Krauss , glad ur a fan of flashlights as well !!!
I stumbled onto this via no film school. I can see this in my horror feature! Well done!!
We love some NoFilmSchool Kenneth Scrues , we visit that site everyday!! Good luck with your feature!!
That artifact is caused by flickering of the LED being out of sync with the shutter speed of the camera. Most flashlights don't flicker as they do not need to use PWM (Pulse Wave Modulation)
PWM !!! Now I know, thanks Gabriel Marigo de Castro , I wonder if it costs more to put in a PWM or if it saves money for the company making the lights.
Shanks FX I believe most LED lights would include some sort of PWM to regulate the power supply
jake carvey Non LED lights (tungsten bulbs) would not need PWM
Gabriel Marigo de Castro
Old topic I know, however, can't you just change the fps or shutter speed to hide the flicker?
I can't really tell from the video what you meant by the artifacting... but PWM is more an issue when the LED needs to reduce its power output (at low power settings) such as what happens with LCD display screens. Perhaps using them at full power will reduce/eliminate it?
Great, easy to replicate ideas. Thanks for sharing.
Very much so Court Laszlo Wright , please share any videos you may post using this technique !
cheap simple, and quick to use ! nice
How did you get all those lights for $150 brand new? The Kobalt link in your description is listed at $190 alone. What am I missing?
Apparently the light has been discontinued, hence the crazy price.
This is awesome! I would just like to know how fast the lenses are that you're using when lighting with your flashlights. Thanks!
Nice vid! Great starter kit for kids to practice and learn on.
That is very true Timothy Lucas when I was a kid, all I did with flashlights is pretend they were Light Sabers
do you look at/consider color rendering index of light sources?
an extreme end example of low CRI being low pressure sodium bulbs (orange street lights), *even if* you correct the footage or white balance, the effect is immediately noticeable.
I'm not sure where LEDs are, i assume they're not too bad, but not tip-top either
To put the gel and magnifying glass what did you use to make the attachment for the cobalt flash light?
so nice guy :))))
Wish flahlights would state their CRI in the specs.
Did a search at Amazon for TrustFire flashlights with 480 Lumens and D cell batteries but couldn't find one that looked like the flashlight you were using :(
How did you get the Kobalt lights to stay on? I have the exact same ones but they turn off after about 3 seconds. Love the video really great ideas
Make sure there are screwed on tightly, could be a connectivity issue JaysVideo
Thank you for posting this! Do you have any suggestions for substitutes to the Kolbalt flashlight? I think Kolbalt no longer makes them, and they're going for $150 on amazon.
Alyssha Rose Jordan they are super expensive , it’s crazy!!!! I’m using the a headlamp by “Coast” headlamp featured in this video more now. Haven’t found one better than that kobalt
Hey. I've got some bi-color led panels and they're great. But I had a very similar idea and am looking at buying a few of these XML T6 tactical flashlights and basic rosco flash gels to do the same thing. Even had the idea of using clamps and ball joints along with bendy tripods and additional clamps to afix on whatever in outdoor shoots. They don't have to be color perfect. Use the led panels for basic key and fill and use gelled led flashlights for background and smoke and hair kickers.
Still a good idea? I love being able to use battery on set instead of having to power by mains.
geeze that torch is huge for only 400 something lumens.
ide get a thrunite TN12 for 45 bucks and up to 1050 lumens and its small.
Ide check out the fenix hl50 and hl55 I beet you like you can adjust the coasts focus but still.
Tom Thomas nice stuff you do :)I was messing with that coast headlamp in a hardware store, I have a Princeton tec apex now with the four double a batteries, I keep getting it because of the warranty, just send it back when it breaks, that and its so comfortable I forget im wearing it and blind people.
Tom Thomas the Princeton tec apex is plastic, the fenix ones are aircraft grade aluminum and bright as hell
what is the backlight w/ 480 lumens called?
When u go to amazon, search for TrustFire flashlights.

I bought some flashlights and they are making a lot of flicker. can you explain why?
Rapid Pulse Modulation, that is the issue probably. Some flashlights are designed that way to save battery.
@@ShanksFX1 You re Right!!! tks
What ISO did you use?
jasam123 usually try and never go above 800
Slashloght
i didnt realize jj abrams was that famous for flares. maybe star wars will take away from some of that
I've got a couple of these. They're small, cheap and powerful. www.harborfreight.com/3-3-4-quarter-inch-32-led-flashlight-98504.html
Can't beat that price Chip Brandstetter , I think I have something similar to this light in my flashlight drawer.
Couldn't you get a bigger microphone? ;)
My lavalier broke, so I went for the extra large Bob Barker mic !!!
