3W Luxeon Star Clone LED
Received 12-24-04, tested 02-06-07

I was sent one of these by a member of Candlepower Forums in late-2004, and I promptly lost it.
I found it today looking for some else though, so as they say, "better late than never".

This is a clone of the Luxeon Star III LED, right down to the hexagonal (six-sided) PCB they come mounted on.

The color is a nearly-pure white, with no unwanted tints.

Nichia America, part # NCCW022, SMD, 70
(Received and tested 03-17-04)
This is Nichia's latest LED to show up in the high-powered LED wars. This is labelled as a SMD LED, even though it seems large for an SMD component. But it has a flat base with the leads going off to the sides, so it can indeed sit flush on a PCB or what have you.


Here are a couple of pictures, showing the new LED both at an isometric angle and from above.

The web page referencing these new LEDs is http://www.nichia.co.jp/product/led-smd-powerled.html if you're interested.


This LED is rated to deliver 23 lumens of light, however I cannot measure lumens because you need a special instrument called an "integrating sphere" to do that, and I don't own or have access to one. And readings in mcd (millicandelas) will seem awfully low, because this LED has a wide viewing angle of 70. If the beam were focused with an optic or a lens, values above 200,000mcd aren't unreasonable.

The Vf of this LED can range from 3.8 to 4.3 volts DC, and you're supposed to supply 350mA to it - 500mA maximum - with proper heatsinking of course.

A flashlight using this LED was supplied with the LED itself, and it has a bright, surprisingly wide beam, even though it's focused with an aspherical lens. The link to this flashlight is right here if you're interested.

The LED itself is very new, and I don't believe it is on the Nichia website or the Nichia Light Emitting Diode 2004 catalogue yet.



Nichia America, part # NSPW500BS (Rank B2S), 5mm round, 20
(Received 11-03-03, tested 12-26-03)
A few weeks ago, I received an envelope from Nichia, containing several LEDs and a small LED flashlight. Here is one of those LEDs, the white NSPW500BS, a 5mm LED in a standard, water-clear epoxy package.


Here's the beam shot on the target at ~12"
Measures 11,770mcd with a test current of 23mA.

According to the book, a standard-ranking 5mm white NSPW500 should emit 6,400mcd. This LED is one of their higher ranking versions, which is why it's brighter.

(Edit) A fan of the website who's work I trust had the following info to add:
Meanwhile, it appears to me that recent Nichia production of NSPB-500BS mostly exceeds the 6400 mcd (at 20 mA) center of rank R, and quite a bit of it makes it into Rank S.
Most white Nichia LEDs that I have received in the past year of R rank appeared to me closer to almost S than center of R.



And here is the same shot of the same LED on the same target, but with the camera's
exposure value reduced by 2, to show the bluish central region of the LED's beam.
This is completely normal for this kind of LED, and does not in any way indicate a problem with it.



Chi Wing 5mm White LED, (http://stores.ebay.com/chiwingledproductshop)
(Rec'd 12-24-2003, tested 12-25-2003)
A fan of the website sent me a box of goodies (like batteries, LEDs, flashlights, and a laser); and 5 of the 8000mcd and 9 of the 4000mcd LEDs were among the goodies.
These are Chi Wing's 5mm 8000mcd and 4000mcd white LEDs. They have an icy cool bluish white color.


Chi Wing's 8000mcd white
Measures 11,990mcd.


Chi Wing's 4000mcd white
Measures 6,990mcd.

Both LEDs were provided with a test current of 23mA.
I'm not equipped to measure beam angles at all. Looks like about 18-22 degrees to me.

These LEDs appear to be brighter than their advertised brightness, and have smoother than usual beams for 5mm white LEDs.



Chi Wing 3mm White LED, (http://stores.ebay.com/chiwingledproductshop)
(Rec'd 10-23-2003, tested 12-24-2003)
A fan of the website sent some of these back in late October; I sincerely apologise for getting them on my website this late.
What they are is a 3mm (T1) sized LED in a water clear epoxy case. These are available for approximately $25 per 100 (shipping included) via Chi Wing's frequent Ebay auctions. The link above will take you to his Ebay store.


This LED lacks the rings and spots normally seen in the beams of other 3mm and 5mm white LEDs.
At a test current of 23mA, one LED produced 2,700mcd, a second 2,700mcd, and a third 3,200mcd. These are advertised as "5,000mcd white LEDs", so the intensity figures appear to run a bit on the low side.



Probable ISP 4-Chip White LED, (www.ledsales.com.au/)
(Rec'd 12-15-2003, tested 12-16-2003)

I received several LEDs from Australia yesterday, and this unusual little guy was among them. It comes packaged in what I believe is an 8mm water clear epoxy case, and has wider than usual lead spacing and larger-in-diameter than usual leads. But the real unusual part is what's inside the LED. Instead of a single die with a pair of bond wires attaching to it, this LED has four (4) dice inside of its die cup, and it's rated to run at 80mA instead of the usual 20mA that regular LEDs ought to be operated at.


Wide, 50 beam lights up the entire test target.
The beam is free of rings, blue blotches or crosses, and other evil little things (artifacts) you find in the beams of most other white LEDs. The color temperature is a bit on the high (cool) side, probably coming in at around 7,000K. Overall, this LED has a pleasant, icy cool white color to it.

Measures 6,780mcd with a test current of 87mA.
Remember, wider viewing angles always give fewer mcd.

These LEDs are believed to be an ISP Korea (International Systems Processing) part. Appears to be ISP part number 8W4DHCB-H.



ETG White LED, # ETG-5CFWHT-30 (www.etgtech.com)
(Rec'd 10-06-2003)
This is marked as a "New Item" on the envelope it came in. This is a standard 5mm LED in a water-clear case. The LED has a pale yellow phosphor when off, and a pure, snow-white color when on. The two test units measured 3,500mcd and 4,000mcd at a test current of 19.2mA. But this is what makes these LEDs worthwhile:



Check out that smooth, round, white beam with none of those evil blue things in it. For many applications, a smooth white beam without blue crosses, splotches, or other artifacts is preferable to a brighter LED with artifacts in its beam. The color temperature seems to be around 5000K, so the lamp doesn't look very blue at all, when compared with other white LEDs.
The viewing angle of this LED appears to be about 30 degrees, but I don't have the equipment to measure this with, so your results may vary.



Wilycon # ? (New white model), Wilycon Corp. (http://www.led-center.com), $0.25 each for more than 50,000 pcs

This is Wilycon's newest 5mm white LED. It comes in a standard clear epoxy package, and the phosphor has a snow white color to it when off, rather than the usual pale urine yellow color. This LED has an overall cool white, even beam without the blue hotspot normally seen in white LEDs. Upon close inspection, a slightly warmer white disk can be seen in the center of the beam; it is faint and not readily apparent however and does not detract from the LED's functionality.


Measured 3,150mcd.

The target I normally use was misplaced; hence the sheet of labels being used as a target for this beam shot. Note the even, white coloration without the annoying blue cross or splotch in the center.
