How does the throw, spill, and tint of the new Peak Seoul P4 lights compare with their older Luxeon counterparts? Do the new Peak Seoul P4 lights exhibit a "donut hole" or other artifacts in the beam?

Hi, Just got my Ti Caribbean Seoul P4. It's nice and bright But It does have a slight "Half a Ring" artifact In the hotspot.

I haven't got mine yet and I am hoping that I will get them on Tuesday. I am really hoping now that mine don't come with rings in the beam!

Thanks for the info, Skalomax.
Anyone else receive a Peak Seoul P4 flashlight yet?
If so, does yours have artifacts, too? How's the throw? Spill? Tint?

A beamshot would be really helpful. I love the smooth beam of my luxeon Pacific and would like to compare it to the new P4.

I received 4 Peak P4s... Pacific, Baltic, Glacier Bay and Kino Bay... all had beautiful smooth beams EXCEPT the Glacier Bay... Glacier has a very nice smoth beam BUT has artifacts in the center; the others have clean beams. Really dissapointed about that because that was the light I planned to use the most and the artifacts bother me (guess I'm a bit OCD when it comes to beams). May send it back... wish they tested the lights before they ship them. I don't have a way to measure intensity but they are at least 50% brighter than the Luxeon versions, probably closer to 75% brighter. I have to say, I love the Kino Bay... bought it just to round out the order but it is quickly becoming my favorite light.

Re: Anyone have a Peak Seoul P4 light yet?
The SSC P4 seemed to give a wider spot due to the larger LED die and is slightly brighter with the same battery at slightly lower current drain.
With a rechargeable 123A (3v, not 3.7v) the P4 Mediterranean measured 0.85A whereas the Luxeon Caribbean measured 1.1A. I believe the Caribbean and Mediterranean are the same electronically
The "Half a Ring" artifact appeared to be the magifyed gold bond wire inside the LED, which in the P4 are not perpendicular to the perimeter of the die.
In the Luxeons, the gold bond wires are perpendicular to the die perimeter and are therefore not visible in the hotspot.
The brighter output and lower current consumption of the P4 is more important then the gold bond wire shadow appearing in its hotspot
parnass08-12-2007 09:08 PMRe: Anyone have a Peak Seoul P4 light yet?
Since starting this thread 4 months ago, I have obtained both Seoul P4 and Luxeon Peak Caribbeans.
Though they each draw about 3/4 A, there is a marked difference in the amount of light output. The P4 version has a considerably brighter spill which makes it more effective at lighting up a room or a wide path for nighttime walks.
Both lights exhibit slight artifacts which do not interfere with actual use.
datiLED08-13-2007 07:16 AMRe: Anyone have a Peak Seoul P4 light yet?
I swapped the Seoul in a Peak Glacier Bay for a CPF member who was unhappy with the tint and horrible artifacts present in the beam. The Seoul was also off center by at least 1mm. In my opinion, this light should have never made it past the QA/QC process.
I used a USVOH LED for the "mod". In trying to get the best focus from the LED, I found that the stock reflector had to be raised about 0.010". This yielded an artifact free beam that had a great hotspot, with a huge sidespill. The notches in the retaining ring for the lens did show, as would be expected. I also replaced the plastic lens with a hardened crystal lens, as the plastic lens had a few small scratches that did show in the beam as minor artifacts.

Did he get it as a pilot run item? A production item should have better QC then this

Doug has retired from doing any new reviews but his site is still up.
The Peak's usually rate very well. I agree with others that quality control has occasionally been a problem for them. Yet, if you can reach them via email, the always respond well to problems. Phone calls aren't as likely to be returned, in my experience.
They are very solid well built lights that give you confidence when using in remote areas.
LED_Thrift08-14-2007 10:02 AMRe: Anyone have a Peak Seoul P4 light yet?
How are the tints in the Seoul Peaks compared to the Luxeon Peaks. I never gave much thought/concern to the tints of lights until I got a few Peak lights, now I see why people care. The "snow white" LEDs are wonderful - do the Seouls also have good tints?

All of my Seouls are very clean. Not the range of "colors" of Luxeons.
dpcheng08-15-2007 02:16 AMRe: Anyone have a Peak Seoul P4 light yet?
The hotspot from the Seoul showed the shadow of a gold bonding wire and is therefore not entirely clean. However, it is more than compensated by its increased brightness and reduced power consumption when compared to the Luxeon.
And...oh yes, the colour rendition is excellent!
paulr08-18-2007 03:08 PMRe: Anyone have a Peak Seoul P4 light yet?
I just got a Pacific 1aa HP Ti thanks to Goatizzle. I've never had much of a clean-beam fetish and I've never had a Peak Luxeon light to compare. But I'd say this light has a small, pronounced hotspot with a slightly irregular corona that is also small; and a quite smooth spill which is slightly on the narrow side; beyond the spill there are a few rings. Peak seems to like designing lights to maximize hotspot intensity even in small lights that will primarily be used at close distances. Goatizzle asked in another thread about the possibility of an orange-peel reflector and I think that idea is an interesting one. However it would need a different shape as well, requiring a shorter head, in order to widen the spill.
Gointothelight08-21-2007 09:13 AMRe: Anyone have a Peak Seoul P4 light yet?
I'm the person datiLED did the "repair" for. This "production" Peak was pretty bad... I did not even consider selling it because of how poor the beam was. BUT, after datiLED worked his magic, I can easily say that this is now the best beam in my collection, and I have about 75 lights right now, some from CPFs best modders. The light went from the trash-can to now being my EDC. All I can say is that no one should buy the standard line that "artifacts are unavoidable." When properly built, these beams can be extraordinary!!! Thanks again datiLED.

Galiphrey09-10-2007 12:30 PMRe: Anyone have a Peak Seoul P4 light yet?
I just received a P4 Mediterranean. The quality is just fine, as far as I can tell. The beam quality is great in fact--no artifacts to speak of, and it seems well centered, and the tint is pretty neutral. They set the regulator at 2.5W, so it's plenty bright for most day-to-day uses. I like it. Oh, and there's a 1-LED McKinley on the other end!

I recently received (2) Pacific 2AA HP and 1 Rainier, all with Seoul P4's. From a distance, there is no noticable donut holes but if you place the light close (couple of inches) to an object, they become visual. The hotspot seems fine, but there is a slight ring at the edge of the spill. Unfortunately, I cannot make reference to any Luxeon models.
Complaints:
My units arrived with slight blemishes, but nothing worth returning the lights for. Also, there is A LOT of dust on the reflectors and the inside of the lens. I think they need to work on and improve their quality control.

I have Pacifics in HP and ultra and a new Pacific Seoul in Ultra. The beam is OK, with a slightly smaller hotspot in the Seoul than the Luxeons. The Pacific ultra in luxeon has a much larger hotspot - the HP is slightly larger than the Seoul ultra. I measured the cp output of the Seoul ultra as marginally greater than the Luxeon ultra - perhaps 10-20 cp. The spill is very slightly brighter on the Seoul compared with the luxeon ultra, but the difference is barely perceptable. The tint appears slightly cooler on the luxeons, but that may be because of a visible gold tint to the material the emitter is bonded to in the Seoul.
The luxeon ultra has a nicer beam to my taste. The Seoul hotspot is clean in the middle, but it has a fuzzy outline. The extra ring of light seems more pronounced in the Seoul. These are minor differences.
I wonder what the runtime difference might be - does anyone know?

Another happy DatiLED customer here with a fixed Caribbean now converted to Seoul.
Peak charges premium prices, and does indeed have good customer service (email worked WAY better than phone for me. phone call NOT returned!) Yet, I too wish their quality control moved up a notch.
