led light bars, will it ever end?

[Pete M]

so I'm perusing the internet for a gift for a buddy and stumbled upon some unbelievably cheap (probably for good reason  ) 52" triple row light bars for dirt cheap.  I had no intention of clicking on it, let alone buying them, but one  number stood out to me so I had to take a closer look... 2871W!!    holy crap!  seriously, how fast would that suck the battery out of his truck?      So I thought maybe it's an exaggeration.  I know that lumens-inflation is a real problem in this market.   

 

by the way, they are claiming over 400,000 lumens.  thems a lot of blindyness.

Just looked it up...
Ip68 waterproof rating is good. Better than the "cheap" ones with ip67 rating.
AND a 5 year warranty. Which is more than most.
Site was asking $59 for the 52". I offered $40. Still not bad for a 52"

All the light bars and pods I have are from FCKlightbars and extremely bright and high quality.

I don't really see the point in that...  I've never thought "Jeez, I need to signal a ship on the other side of the Pacific" or "Damn would it be nice to have a tan in January" or "That whole dark side of the moon thing really bothers me."

 

YMMV

 what's the plan for powering that bad boy  

[krustyballer16]

A battery or 7. Duh lol.
But not sure. Doesn't give an amp draw. $55 for the brightest light on earth, I'll try it. Ha.

Man, we ain't got nothin on the JK guys.

^^^you owe me a beer....(for the one I just spit all over my iPad, LOL).

2871W at 12V is only 230A. That's only a little bit more than a starter motor. Should be fine.

Lol. Enjoy that portable sun. 

[Pete M]

it needs to make a huge noise each time it turns on.  maybe like the big notes in the movie Inception. 

 

something worthy of a death ray

Is this 2871W worth of actual LEDs or 2871W equivalent? If it's the latter the draw will be less. A lot less. If this portable death ray actually draws 2871W... holy crap. That's a lot of LEDs.

Says 261leds at 11watts per.... I'll find out in a week or so

2871 divided by 12v equals 239.25 amps.

 

There is no way that light is drawing 200+ amps. 

[Dzimm]

Are we sure there wasn't a typo somewhere.  I'm guessing there is a decimal point missing, like 287.1, which would make it draw just under 24 amps.  Cannot see how LEDs could draw 200+ amps.  

[89eliminator]

I'm guessing typo.  a lot of the other triple row bars are in the 200+W range.

[HOrnbrod]

Another example of LED light marketeering.

[krustyballer16]

yay
I found an even "brighter" one too! 3200watts. For $77

[Pete M]

how many lumens in the 3200 one?

[krustyballer16]

313,000 compared to the 2800watt with 445,000. So obviously they have no idea

I seriously doubt they have a clue what they've got, but it'd possible for the ratios to be off since different LEDs put out different amounts of light per watt.  better LEDs will use less power to obtain the same lumens.  watts is just power suckage, lumens is the light output.

 

I still say they are full of it.   

 

 

on the subject of lightbars, I went in with a couple more friends to buy my buddy a big honkin' light bar for his big honkin' f250. we went with a lower lumen claim (70k) but with a better lens claim (4d).  still cheap as hell though (60 bucks and comes with wire harness).  oh, and a couple small LED pods for bed/backup lights.  I'm infinitely curious as to how the main bar would compare to the mini-sun you got.

We shall see. My FCK lightg bar is amazingly bright. And it better be for $400.
If this cheap light bar only works for 10 seconds, but starts a forest fire a mile away at noon, I'll be impressed and it was worth the $55. Ha!

from what I've read about its reflector style, I doubt it'll focus that far away.   

 

but you will see everything inside that radius, whatever it might be.  maybe bordering on xray vision

It actually just got delivered. I'll try it out tonight if I have time at work

I'm going to chime in with my light bar..... i love it. Its mounted just at/ below the top of the roof line. If its angled properly don't get any wind noise anymore, but a load in the bed can change the angle and the noise begins. Mine has a breather vent and hasn’t had any moisture issues. It also claims to be a 5d setup i think, (has both a reflector and lenses). As for the amp draw the seller i bought mine from said its the theoretical max amp draw.
