Is this real? crazy 32000 lumens (video inside) edit:its the real deal.

I dont get on youtube as much as some people so this is probably old news, Is this real?! the power and amount of led’s makes me think it must be fake, but its on youtube so hey.
Experts please enlighten me….

Overexposed video. In real life it doesn’t looks anything like that.

That would be 250 Watt from that rather tiny battery pack… I am skeptical… :cowboy_hat_face:

edit: …with 5 or 6 18650 IMR’s in this pack, it’s possible thogh…

Uhm… a RC Li-po battery that size can deliver 5000W without a problem. So it’s quite possible.

… I just realised that as well… I am feeling dumb now. :party:
…I always think 18650 Lion… S)

Some rough back of the envelope calculations, it look like it is possible with that size battery.
So citing probably the best cordless drill battery as a example, the dewalt 36v 2.3ah, has 36x2.3 =82 watt hours. This light takes ~250W not including driver and cooling, which must be massive. 60 / (250/82)= 19 minutes run time.

But 48 XM-L in that head with 10 degree optics? I’m still sceptical…

First I thought it was a modified Ryobi torch

But the vacuumer looks more like it :open_mouth:

Not sure I the spec’s are true but they also have a less powerful light compared to car high beams

Meh, the Chinese will sell you a 32,000 lumen single AAA keychain light for $3.99 :wink:

I emailed them at the address they list on their video: xled@concepts.nl and they sent back some interesting info and some better pics. Hope they don’t mind me reposting some of it here.

What kind of run times does it have? Does it have more than one mode? Is the battery unit sealed? How much is the light? How much are spare batteries? Has its lux been measured at 1m? Do you have a website with more pictures of the light? Are they custom built? We got 15 minutes run time on full power on a 48W/hour Li-ion battery The X-LED Ultimate has got 2 light levels/mode: 8000 Lumen 1.5 hour 32000 Lumen 15 minutes With the new light, we are planning 4-5 levels of light

There are now new batteries packs with almost 100W/hour with the same size.
Only available in the US.
So we got a good customer in the US with who we work together.
He’s testing the lights on expeditions, and shipping the new batteries to us.

Battery time is double so 30 minutes at full power and 3 hours at 8000 Lumen.
You can see that 8000 Lumen is already a pretty respectable light. (see video XLED 32000 Lumen)

Lights are Euro 1200,- with charger and 2 battery (48W/hour) packs
For the US, I send for 1100 Euro without the batteries and charger.
Around 120 euro for shipment. 3-4 days Fedex
For batteries look at the Ryobi website. I’ll expect between $60 and $80
Batteries can be used in moist whether, but if submerged the small expansion holes will fill with water and the battery will be destroyed. However in contrary to wild stories it doesn’t get hot or explode.

LUX versus LUMEN
Lumen is the total output of light
1 Lux is 1 Lumen per square meter
At 1 meter the spot is 25 x 25 cm so it should theoretical be 4x4, 16 x 32000 = 512000 Lux.
Calculated from the Lumen output of the 48 Cree XM-L U2 LED
Now there are losses from the output source to lenses of around 25 %.
So I expect measurement of around 350000 Lux and 400000 Lux on 1 meter distance.
I’m working on the website
Enclosed some pictures

Custom built? We like new projects on any extreme powerful light, so if you have something in mind?
Marine, helicopter ect. Even to 1 million Lumen with front surface of only 20 x 8 inch (1200 Cree XM-L)

Light’s are handmade using quality components. Thermal management is key to le(d) it work.
We run the LEDs at low current of 1.4 to a maximum of 1.8 Amps
Many lights are running with Cree XM-L at 3.0 A and even 4.0 Amps
Not only the efficiency drops at 3.0 Amp. It generates much heat and the lifetime will be only be a couple of hours.
At 1.4 Amps it can run for 20000 hours.

so mass production of these lights would sell ? :slight_smile:

Those Ryobi packs are 5xPanasonic INR’s (Basically” these”:This product is no longer available. ) and the bigger ones are just wired in parallel with the others to add more capacity.

I’ve got a pack sitting apart here with one dead cell, unfortunately somehow in the design one or two cells tend to become unbalanced and die, refusing to take a charge and essentially killing the pack (Since the protection circuit doesn’t work after a cell dies/voltage dips). Not a great thing but when they work they are a heck of a lot better than the old ni-cad cells or many lead acid one’s.

I’m going to just run lipo’s direct for a while though, much more power at a lower cost than is available with commercially available packs right now. I wonder why they even bothered making a custom light with such a pack; True it saves development time but I would just rather opt for the higher density and extended power levels of Lipo’s and other larger dry cell Lithium based batteries.

A lot of the tool packs power the protection circuit off of the first cell in the chain. The parasitic drain on the cell discharges it faster than the other cells resulting in what you saw if you don’t keep the pack charged regularly.

Go google the Lightpipe 250W. Last year I ordered one for usd530 shipped (believe shipping is about 98 bucks). That’s a 7” reflector (PAR64 if i rem correctly) 250W metal halide “HID”, with a 4mm arc gap or something. But the deal did not go through due to some unknown reason. The Li-ion packs were bad, but i was prepared to replace it anyway with my own Li-po packs due to safety concerns.

In the end i opened a PP dispute and got my $$$ back.

Shd be approx 25k lumens for that one. And throw a hell lot more.

The optics appear to be the led domes themselves, or is there a secondary optic on each of them?

It’s probably hard to tell from the thumbnails I posted, but the full-sized image shows what looks like TIR style optics to me.

So can you post the full-sized images too please?

I didn’t before cause they’re quite large, but here you go. Click link for full pic.

He also sent two pics of a helmet mounted light too:

It looks good, but I am a bit skeptical of the 400kcd throw and 32000 lumen claim.
How is the heat managed? Even at 1.8A, 48 XM-Ls would create quite a bit of heat - and I don’t see a very large surface area to wick away the heat.

Maybe it still got the vacuum motor inside to suck away all that heat :bigsmile:

If it is 1.4A per LED as claimed by Max, a XM-L will give around 520 lumen at 1.4A.

There are 48 LEDs, so it is going to be 48x520 = 25000 lumens approx.

Also note that 25000 lumen is produced by the LEDs, not OTF. Still long way to go to hit 32000 lumen, isn’t it?
