How do you know exactly where the nearest aliens are ? Cause you said they were 2.05400 × 10-^13 light years away, that's about 1.83836282 × 10^16 KM :D

Hensch There's still light pressure, the laws of physics don't work the same on photons. They give off a very very small, but measurable pressure on the object they hit. On Cody's Lab he measured this effect.
I remember seeing a post on reddit from someone who worked on a music video shoot, they strapped 9 high power LEDs onto a octocopter if I remember correctly.
@ I mean light bars are not DOT-approved, they're for off-road use only- and are a better alternative to super-bright headlights which will be used on-road too. The problem is when people install aftermarket super bright headlights in non-leveling housing, even some OEMs with self-leveling are really bad with this, like the new Cadillac Escalades, Range Rovers, or a lot of Toyota trucks/SUVs
@ I actually agree on the autoleveling and maximum lumens, autoleveling is not quick enough to account for bumps and can't predict the crests of hills. So you do end up dazzling oncoming drivers. Modern headlights are too bright, or even just intensity wise they have too much light from too small an area
Holy crap! Every morning on my way to work I dread this one Jeep with those stupid ass sun beam headlights ending up behind me. I swear one day I'm gonna follow him and spray paint the damn things black!!
Based on the batteries he's using and the 11 LEDs, less than 4 and a half minutes. 36 volts at 2200 mAh is 79.2 watt-hours. 1100 watts of LEDs. The math is exceedingly simple. However, the cooling system is woefully underpowered and will very quickly be overwhelmed by the 1KW+ of thermal energy being dumped into it.
Funny you mention that...I recently made something similar to this using three 750 mW LED's in parallel. It required about three 15 ohm resistors (Capable of handling 25 Watts each). I slapped it on my motorcycle and it works great. It gets pretty hot after an hour but so far no melting or loss of brightness.
I am editing this comment because I just realized Sam was killed in a motorcycle crash in 2018. My condolences to his family. That’s awesome. My son collects flashlights. He’s amazed by your light. Market that to first responders and anyone for that matter. Imagine every house in your neighborhood with a 72,000 lumen night security light.
Now that is actually an incredible idea due to the cooling nature of it - on the sets of films lights can become dangerously overheated and required gloves to operate - liquid cooling flood lights are quite a good idea
andthen put on a speaker, then go outside someones home light up straight to window and put speakers to "You are surrounded, exit your house or we will fire"
The whole DC AND Marvel universe would turn up with the power of this light, that would break the internet though, imagine batman having to stand beside superman...............possibly even rubbing shoulders? Just gonna put that one out there.
I was going to ask Sam Shepard to make me one and I would pay him. But i see he has passed. Rest in peace. We need people like same who create and invent to make innovations like these.
How much does it weigh? You should attach it to a drone and fly it at night over a city. The internet will be flooded the next day with pictures and footage of an "alien sighting" 😂😂😂
a standard battery pack or a high voltage setup with capacitors and dc-dc converter would work pretty well. Just wired up a few packs of rechargeable batteries 48-72v and use the caps to keep keep constant voltage on the backside of the converter. Will keep pretty constant voltage and let you slip a new pack in. Pretty simple if you have the know how ;) the high voltage helps keeps the draw lower and the caps wired in will boost it when wired in right.
sjpro1 Perhaps a good idea. I Engine cooling systems run hotter than this does, but would still keep it in a good range. I'm not sure I would like to run seawater through this though
***** Just spit balling, there is a pretty big market for long range lighting in the desert racing and marine worlds. You could have pretty good success if you could make these reliable enough to hold up to a baja 1000 race.
Would be nice to know about how long you can keep that running, how quickly it drains a battery. Also, what would.the durability be like for the LEDs and the batteries if it was to be used fo like 2 or 3 hours straight on a regular basis.
That's the exact reason I'm building this. Next time a cop shines his puny little plebeian light I'm gonna pull out my much brighter light to prove how big my cock is. Hopefully I get shot and it will be on the news as unarmed man shot dead because of flashlight.
next time remove the resistors, use a current mirror for control, and PWM it, so you can go 1/10th pulse but 10x the power. You're effective brightness will be much higher and controllable
Peter Twiss I am in the early stage of making a water cooled flashlight. Would you please elaborate on what a current mirror is, and how do you get pulse width modulated power? The LED's I purchased were a bit expensive, and I really want to make sure that I power them properly and not risk burning them out. Thanks.
Edit: I should have paid more attention to your comment, you clearly already know what PWM means. You asked how to do it. Use a transistor or MOSFET to open and close the path to the power. Control that gate with either a timer circuit (555 chip in an astable configuration (I think))[hard and cheap] or a microcontroller such as an Arduino or PIC chip [easy but not cheap]. Some microcontrollers come with a PWM function built in, others you would have to write it, but the code is simple and straightforward. @@garyrice8198 what Peter said does not make sense to me. I'm not an expert but I do know a few things about electronics and LEDs. He's talking about Pulse Width Modulation (PWM), you can get enough reading on Wikipedia to understand what it is. Basically though, it is the process of turning the LED on at full power for a period of time and then turning it off for another period of time. The apparent brightness of the LED while doing this is the ratio of the on time to the total time. This is how LEDs are dimmed, rather than lowering the instantaneous current. The cycle time is so short, that the human eye usually does not notice that the LEDs are blinking. However, you can observe this effect by waving your hand in front of a dimmed LED, you will observe a strobe light effect over your fingers. Now, what Peter suggested was to overdrive the LEDs at 10 times their rated maximum output but pulsing them at a cycle of 1 part on, 9 parts off (1/10th)[1 part on/10 parts total]. The weird part is where he claims the perceived brightness will be greater. To me, that makes no sense. The brightness should be the same as driving them at the rated current and constant on, because 1/10th times 10 = 1. I also find it weird that he wants to pulse the light at full brightness. But like I said, I'm not an expert and there could be something I'm missing or don't know about. But then again he didn't reply to you and he didn't elaborate, so who knows. In any case, how is your flashlight project going? Got anything to report back on?
Help me lol.. I got a boost converter that can control current but when I turn voltage up to 35v from 12v and try adjust the current down to 2.5-3a it resets the boost voltage to my battery's 12v.. I'm trying to power one of these LEDs and regulate the current but it's doing my head in.. could I use a 10w 1ohm res if it's just 1 led? Or is there anything I could use inline with the boost converter to limit the current to 2.5 - max 3amp? Advice would be good thanks
I'm trying to build one of this but only with 4 LEDs instead of 8, what power supply should I use for this? Can I use 12volt 5 amp battery to power all the LEDs? Is it possible to have some sort of circuit diagram? That will be great! Thank you so much. PS. Do I separately supply power for the fan and the pump?
How much would a build like that cost if you got those lenses for free from old overhead projectors? (I've seen those lenses on them so I know where I'd search :)
If you focus this light, I bet it turns into a weapons-grade laser. No need for pistol when you can just punch holes in skulls with pure light. Pew pew pew!

Have you ever asked yourself why your choices in life have led you to repeated instances of police flashlights shining in your face at night...?
@@BDNeon probably because he goes out at night, while you sit and troll people.. Just a thought..
next time remove the resistors, use a current mirror for control, and PWM it, so you can go 1/10th pulse but 10x the power. You're effective brightness will be much higher and controllable
Peter Twiss I am in the early stage of making a water cooled flashlight. Would you please elaborate on what a current mirror is, and how do you get pulse width modulated power? The LED's I purchased were a bit expensive, and I really want to make sure that I power them properly and not risk burning them out. Thanks.
Edit: I should have paid more attention to your comment, you clearly already know what PWM means. You asked how to do it. Use a transistor or MOSFET to open and close the path to the power. Control that gate with either a timer circuit (555 chip in an astable configuration (I think))[hard and cheap] or a microcontroller such as an Arduino or PIC chip [easy but not cheap]. Some microcontrollers come with a PWM function built in, others you would have to write it, but the code is simple and straightforward.
@@garyrice8198 what Peter said does not make sense to me. I'm not an expert but I do know a few things about electronics and LEDs. He's talking about Pulse Width Modulation (PWM), you can get enough reading on Wikipedia to understand what it is. Basically though, it is the process of turning the LED on at full power for a period of time and then turning it off for another period of time. The apparent brightness of the LED while doing this is the ratio of the on time to the total time. This is how LEDs are dimmed, rather than lowering the instantaneous current. The cycle time is so short, that the human eye usually does not notice that the LEDs are blinking. However, you can observe this effect by waving your hand in front of a dimmed LED, you will observe a strobe light effect over your fingers.
Now, what Peter suggested was to overdrive the LEDs at 10 times their rated maximum output but pulsing them at a cycle of 1 part on, 9 parts off (1/10th)[1 part on/10 parts total]. The weird part is where he claims the perceived brightness will be greater. To me, that makes no sense. The brightness should be the same as driving them at the rated current and constant on, because 1/10th times 10 = 1. I also find it weird that he wants to pulse the light at full brightness. But like I said, I'm not an expert and there could be something I'm missing or don't know about. But then again he didn't reply to you and he didn't elaborate, so who knows.
In any case, how is your flashlight project going? Got anything to report back on?
Help me lol.. I got a boost converter that can control current but when I turn voltage up to 35v from 12v and try adjust the current down to 2.5-3a it resets the boost voltage to my battery's 12v.. I'm trying to power one of these LEDs and regulate the current but it's doing my head in.. could I use a 10w 1ohm res if it's just 1 led? Or is there anything I could use inline with the boost converter to limit the current to 2.5 - max 3amp? Advice would be good thanks
@@MatthewStauffer above
@@brandonthatcher7781 probably you're drawing too much power from the converter
I'm trying to build one of this but only with 4 LEDs instead of 8, what power supply should I use for this? Can I use 12volt 5 amp battery to power all the LEDs? Is it possible to have some sort of circuit diagram? That will be great! Thank you so much.
PS. Do I separately supply power for the fan and the pump?
장현진 you are asking so primitive questions that you will never make it on your own.
I Don't know why I was Recommended this but i'm glad I was.

How long could this be turn on without overheated?
wont overheat
I was just thinking that about search and rescue, you could see that thing from miles away and move towards it as someone who was lost.
How much would a build like that cost if you got those lenses for free from old overhead projectors? (I've seen those lenses on them so I know where I'd search :)

I want one! ... Please tell me how much it'll cost me for you to make it for me? Thanks is advance!
A car battery is 12 volts will you be using a led that needs 12 volts or some like the ones used in the video?
if you make it.. let us know
Rest in Peace Samm Sheperd, thank you for sharing this

Can i get it in a pistol mount?
James Palmer
It IS the pistol
If you focus this light, I bet it turns into a weapons-grade laser. No need for pistol when you can just punch holes in skulls with pure light. Pew pew pew!

nope its not a uv light
