High-power 5 Watt GREEN LED 180-190Lm

[YardDog]

Anyone know anything about this one. 5 watts and it says it has it's own driver. What am I missing?

Maybe it's just that it's from Hong Kong, seems too good to be true.

Either the guy is dishonest, or he doesn't know what he's talking about. From the lesser pic he's showing, I think he's selling a LuxIII Green. I have never heard of a hi-power LED in on a star circuit board with a built in driver.

Also, do the math. 1050mA (Round down to 1A) X 3.4 - 3.6 (Generously rounded up to 4v) = about 4W

[Darth Morbius]

He's giving the Luminous Flux for a Lux V, but the Ratings for current and Voltage of a Lux III.

I would ask what the numbers are on the back of the LED...

It's hard to tell from the super blurry photos. You can usually tell the difference between a V and a III by the shape of the wafer, and of course the size of the backplate. To me those look like Lux III's in the pics

[Hasid Lafre]

In one pic it looks like it says luminaled or something like that.

[Darth Morbius]

After looking at it, he's selling cheap knock offs and using Lumileds (Philips) LEDs as a stock photo in the item description.

They're "Lux III" HK specials...

Avoid.

Just buy a Seoul P4 Green LED. They get pretty close to that brightness.

[YardDog]

Seoul P4 Green LED. Got it. Do you have a favorite vender?

Thanks for the heads up all.

[Kant Lavar]

LED-Tech.de isn't bad, and pretty reliable. If there's enough demand, though, I'm pretty sure that Tim could stock them in the store. I know he has a source for the white P4s.

Care to weigh in on this, Tim the Enchan... - I mean, Tim the Saber Maker?

Well Led-tech.de can take a little time to ship. Also the prices can be a little high on some of their stuff.

Lux III greens are just fine. Why spend the time and money for a P4 when the Lux III are commonly available?

[vargose]

I agree Tim definitely should stock the colored Seoul P4s

[vargose]

Because a P4 green is brighter than a Lux V green with less power requirements.

P4s have the reputation of being richer colors across the board.

[FenderBender]

I wouldnt say that they're brighter than a lux V, but it IS bright. They can be found for a good price at some of the links provided. Google is a good friend too, though I think we should urge Tim to carry the range of colors so we can give him the business instead of automatically pointing others elsewhere. For the record though, the P4 blue is AWESOME!!

[vargose]

Ok I'll correct myself

Green
P4 182 lumens
Lux V 160 lumens

P4 Blue is brigther than Lux III at 38 lumens.

P4 Red isn't as bright as Lux III at 108 lumens.

But again, I hear the colors are awesome.

I definitely agree with not sending people somewhere else. I just edited that out of my post.

Lets encourage tim to stock the colored P4s

[Roy's Blues]

The P4 is on the bottom, and the Lux V is on the top
Lux V is set on 46 in the current settings on a CF 3.0 with a 7.2 TCSS battery pack
P4 is set on 60 in the current settings on a CF 3.0 with a 4.8 TCSS battery pack
no light

My camera sux.
Granted that the 7.2 pack will kick a ultrafires 14500 2 pack in terms of brightness and runtimes all day long. But you can see they are close.
I have been a fan of the P4 color series for a while now. They kick the crap out of Lux III. For greens I always go with a Lux V, provided it can be powered properly. Otherwise I use a P4 green
For Reds and blues, I always use the P4.
When I sent Master Yoda a CF 4.0 for my Negotiator AOTC #7, I sent a Blue P4 for him to use, and he was impressed with the results, and so was I.

Are you looking at the same stats or are we talking about the same LED?

Technical specifications from Datasheet for the P4 Green Z-LED series star:

power consumption: 1.14W (350 mA) - 3.25W (1000 mA)
luminous flux (typ.): 70 lm (350 mA)
luminous flux (max.): 160 lm (1000 mA)
viewing angle: 130°
wave length (typ.): 525 nm
forward voltage: 3.25V
LED current (If): 350 mA/700 mA/1000 mA
housing: waterclear
material: InGaN
operating temperature: -40°C - +80°C

Well it may be that Lux III greens are just fine.

All good and true. But I have two Lux III (one is green) and the brightness is not knocking my socks off. I'd like something a little brighter...maybe the K2, I'm still investigating the possibilities.

I want to run a hasbro board on the same battery pack (6 volts) so I don't want a 5 watt, but I'd like a similar brightness if possible.

Any opinons there?

[FenderBender]

Well then....the P4 is your option. It uses the same power as a LUX III but is way brighter than a III. Just not as bright as a V. I dont see any point to using a K2. P4 Blue eats the III alive in brightness and its an AWESOME color.

[YardDog]

If it's as good as you say, I don't see any point in using a K2 either. Have you got a reputable supplier? Preferably one with an english language website please (this is not a complaint, merely a preference).

Otherwise I have been thinking along the lines of a K2 (I have a reliable source for those) and two 700ma Buck Pucks, in parallel of course. I'm thinking that should get me in the ballpark.

Opinions?
