High wattage LED

[mjoekingz28]

I am wondering what is the most wattage a single LED can use. And is the light output impressive?


I think HEDs max out at 1000w in an HPS or MH and put out about 100,000 lumens.

IDK what the max wattage is, but I have some 17k+lumen LED lighting at work that are equivalent to a 400 W MH bulb. I also have a 1500 lumen flashlight that will just about give you sunburn...

For a single bulb? Or are there many?


I would rather have a single LED than ten or twenty that really do nothing for intensity.

Are you looking to light something up far away? Then you're better off with HID or incandescent right now. A big HID spotlight will go much farther than an LED.

If it's short range(100yds or less) then LED wins

For life span and efficiency you're much better off with a larger quantity of LEDs on a large footprint.

High Wattage LED(s) in a small footprint = More heat = lower efficiency and shorter life.

There are a number of companies producing LED fixtures for the architectural market that are in the 100W to 200W ranger per fixture. They are using them as replacements or new construction units where traditional metal halide or sodium vapor fixtures would be used. Think gymnasiums, theaters with very high ceilings, etc. The output is impressive.

What something like this.

Is there a replacement for the auto paint detailers who use 500w halogens. I want a 500w halogen, but would like to have a good led lamp and flashlight.


I am usually too timid to pony up the dough for an expensive light because I think it will be junk. There are soooo many to choose from it is like you can't go right.


I want a simple, single flashlight. None of the low beam, high beam, strobe functions that you have to cycle through which seems to wear out the button on top of being stupidly annoying. Just a short range, maybe up to one inch close back to 20-30ft away. Maybe the police are finding good lighting.



Then I want one for lighting up the carport like a 500w halogen would. I want it to cast out shadows and if a LeD can do that I would gladly pass on the heat of the halogens.

 

[mjoekingz28]

Ok, I will try to go into better detail.

A mini mag led may be what I want in a hand held, even though I wasnt impressed with the old clunker D battery one. But, a mini Maglite which looks to go easy in the hand, is battery powered and hopefully puts out a focused beam.......say a 10 foot diameter of light at 10-15-20 yards away.






Then for the 500w halogen (or LED equivalent) I want to plug it into the wall and light up the underbody of a vehicle. So it should probably have a stand that can point in different directions, an on/off switch and maybe a grill to prevent accidental dropping, bulbs shattering and going everywhere, and maybe keep dirt and fluids out of the important parts. Is there one I can find locally? And I would like to be able to use it as a detailer would a 500w halogen when looking for imperfections in paint in either the daytime or at night. If a locally sourced LED cannot do this, then I will probably put up with the heat of the halogen!



Thanks all!

There is no need for a single giant LED. They are so reliable that it doesn't matter. You should be looking at total output, CRI and lens design. Get a high CRI led, like a CREE and the correct lens to throw the beam you want. ie spot, flood.
For around the house and auto work a M18™ TRUEVIEW LED HP Flood Light would be a nice long term investment.

 

[zendriver]

Quite the opposite.

With LEDs, its all about the light output, not a focus on watts. Less is better, not more.

Sam's club has an outdoor nightlight, that I thinks was 65 watts, but I'm not ready to invest the $60 or so.

 

[simpler=better]

You want one of these two lights. The spot one will light stuff up farther away, but can be annoying up close. The floddy one will probably be better for body work.

Spotlight One

Floody One

I have the baby brother that runs on AA batteries, because weight matters more to me crawing under equiptment. I have to the change the battery every hour or so, but that's okay because I'm not in the dark for that long.

Get two of their super duper batteries ($15/pop) and this charger(can charge in the house or car)


You will be $140 in on it, but you'll never buy another light.

Alternately, the cheaper way is the AA baby brother for like $70 and use whatever AAs you've got kicking around.

 

[simpler=better]

For fixed lights, you can probably rig these cans into something portable. They're high CRI, so the colors are closer to incandescent and don't look faded.
I have these in my bathroom and the light color matches my soft white incandescents over the vanity perfectly.

The original point to this thread was to see what type of lumens a single led can put out. I dont know if you consider multiple leds in a single setting one bulb or many- as a led is a diode, I guess, and not a bulb in the sense a cfl or incandescent is.



So, what can a single LED do? And what is common light output for a regular single led? Not like the super worlds brightest as posted above, but we all know what a single incandescent, single cfl, and a single HED can do.....so how many watts and what kind of lumens can one single led bulb put out?





Ya know, then I am looking but the threads I see on the net just throw out many suggestions and just serve to confuse. So, I will seek the mini mag pro led as my hand held....and I am asking around as to what to 'light up a room' or 'illuminate the underside of a vehicle at night' type light I can use for repair work, general lighting, and paint correction (revealing small swirl marks)........

Zebralight pops right out of that headband and goes in your pocket.

Big Zebra: 1,000 lumens, 2 hours on high. $140 for light+batteries+charger.
Little Zebra: 250 lumens, 1-1.5 hours on high. $70 bring your own AAs
MiniMagPro: 250 lumens, 2 hours, $25 bring your own AAs.

It's a big price jump, but you won't regret it if you use a light daily.

Cree XHP70 up to 4022 Lumens 7mm x 7mm 32 watts. Arrange a couple side by side and you have more light per watt then any other style of light. They get better every day too.

 

[cybrdyke]

I'm not exactly clear on what you're asking, but....there are single diodes in the laboratories that are over 200 lumens per watt. Not that it's relevant, cuz it doesn't really apply in the real world (yet).

 

[Platonic Solid]

This is just silly. If you want the highest wattage capable LED, look up all the LED manufacturer's and browse their sites.

Keep in mind that you will never actually achieve the 4000 claimed lumens and high lumen per watt efficiency at the same time from an LED like the Cree XHP70 mentioned above. You can have one or the other. Maximum efficiency will be around 25°C junction temperature which will never happen at the 30 Watts required to reach maximum lumen output.

 

[mjoekingz28]

Cool, thanks for the Cree video short!

I am mainly wanting to keep tabs on the advancements made in lighting as Alexbn921 stated. It is really neat stuff. It appears to me that heat is going to be a major limiting factor.


I used to get excited about CFLs. I thought ' man, four times the light output of an incandescent on the same wattage' ....but then I felt the bulb, and while LEDs and CFLs bulbs do not get very hot, the fixture or the base does get really hot. I thought it was a win-win. So, I think a 25w incandescent's base/socket will run cooler than a 25w CFL or LED would. I either overlooked this for awhile or the bulb makers were not forthcoming in this knowledge. Heck, heard CA was going to ban incandescents! Then I dont think they ever told us that they cannot take alot of on/off cycles- they just stated how great the hour lifetime was. Kind of deceptive practices dontcha think?




I dont like seeing the coils of CFLs. It just looks cheap and who knows what kind of radio frequencies they put out like bad ballasts do in fluorescent lighting. Floros can be beautiful. While, HPS streetlights really compete with headlights and are almost counter-productive when it is raining and everything is wet!

This is a LOT more difficult to answer than you anticipate. THis is because even a single "LED" can have multiple LEDs on the module.

For example, see this CREE XM-L:

Notice the three wires on the module, this single "LED" consists of six LEDs wired in 3x2 formation.

Or this brand new xLamp CXA2 which puts out over 6000 lumens!

This one has 24 individual LED dies wired in some combination of series and parallel.

Pretty much ANY led that uses more than around 300mA or more than 3V forward, is using multiple LED dies in a single package. The exception to this is the Cree XML2 which does appear to use a single die from all of the shots I have seen.

Thanks guys,



Very good info and I have learned something today.
