Seoul P4 lumens

[Darth Cruor]

How many lumens does the Seoul P4 (white) have? More or less than a white K2 or III?

[xwingband]

III = 80 lumens
K2 = 140 lumens
V = 120 lumens
P4 = 240 lumens

[Darth Cruor]

Wow. Lotta lumens on that.

[Novastar]

I can vouch that a P4 white with a nice yellow Lee filter (something like 85% transference) is almost indistinguishable in terms of brightness vs. any "mainstream" colored LED of similar volts and amps and so forth with a similar diffusion style, blade length, optics, etc.

We didn't try any other filters at the time, so... I really don't know what would happen if you tried something as deep as purple or blues. Those tend to cut the transference by a landslide and so... it's pretty harsh on the brightness!!

But yeah... as a white, the thing is pretty great.

Got a pic of that yellow blade?

I posted these pictures somewhere else recently, but I'll put them here too for you.

White Seoul P4 running at 1A. For comparison purposes, the camera settings are the same in all the pictures. I adjusted the camera to show the most realistic pictures of how the blades looked.

The yellow filter I use is cut from a pair of ski goggles, but if you got the Lee filter swatch book, you could probably match it.

Go to this site: http://www.leefilters.com/

Find the "contact us" page, and ask them to send you a swatch book. They'll send it for free. It's got every color under the sun.

[darth ney]

sweet thanx, i do have the swatchbook from lee fliters.:D

[Donnovan Sunrider]

Thanks from me too!
I read people talking about Lee filters, but I didn't know what they were specifically referring to. I just ordered a swatch book myself. :D

[Obi-Dar Ke-Gnomie]

The neat thing is that the filters are paper thin. (Maybe even thinner.) You can put them on the inside of the blade holder, between the lens and the ring it sits against. That way, you won't lose your filter when you take the blade out.

[darth ney]

hey Obi-Dar Ke-Gnomie, can u put in ur best orange lee filter with that p4 so i can see what it looks like. i have done it before but cant remember how good it turned out. thanx:D

[Donnovan Sunrider]

Nice. I need a good purple, so the blue & red combo looks like a good option.

[Obi-Dar Ke-Gnomie]

Ney, I'll do that for you later tonight. We're off to the beach to watch all the tourists go home! (Yay!)

Donnovan, check out the difference in brightness between the yellow and purple. The camera settings are the same in all the shots. In order to get a good purple, I had to use a pretty dense filter. It's a nice, rich color, but I lost a lot of lumens.

For purple, you would be better off in the long run to get a Prolight RGB and run the blue and red together.

[darth ney]

ok i guess you got to busy. nevermind then.:confused:

[Obi-Dar Ke-Gnomie]

Sorry bud. I have a wife and a son, two jobs, volunteer obligations, and more.

In other words, I have a life outside of lightsaber building.

I'll take the picture, but I shouldn't have said that I would do it right away. I may get to it tonight, but no promises.

[darth ney]

oh no i di not say what i said out of anger,, i just knew that you where busy is all. i understand what ur sayin, just about everybody else here has a life outside of sabers. its all good man get to it whenever you get the time.no big deal:p

[Zero Unit]

I'm really liking the color of two red filters...pink, but more reddish than pinkish. How does it look in person?

[Obi-Dar Ke-Gnomie]

Ney, Sorry I was a little grumpy. I've had a rough couple of days at work. I'd like to do an Xwing style blade test against my boss' head.

Anyway, here's a picture for you. Just for comparison, the camera settings are the same for all the pictures.

In my opinion, the Deep Golden Amber gave the best "orange" out of the set, but you can see in the comparison pictures, that you lose a lot of light.

I'm using a disc cut from a pair of ski goggles as my default color, but the Oklahoma Yellow is pretty much a dead-on match for it. I just threw that in for comparison.

The 105 orange filter was a pale peach color when I used only one thickness. The color didn't quite show up right on camera. It was better with two thicknesses, but I wouldn't call it orange. More of an amber.

Hope this was helpful.

(Whoops! Just noticed a typo in my pictures. I typed "No Fliter" instead of "No Filter". Oh well. I'm not going to fix it now.)

Not very impressive. Cool color, but I'd estimate that I lost nearly half the light output.

[Novastar]

Right.

If you look at the "transference" or transmission or whatever the bloody name for it is... on Lee filters, btw... you'll see things like a graph and "40%" or "48.23%" and other uber-nerd terms for light.

But to those new with that... higher=better.

Obviously, you'll find that BLUE filters tend to have LOW transmission, and YELLOW filters tend to have HIGH transmission. To a point.

Anyhow--the best you'll usually see (with WHATEVER) is like 80% or 85% or something. Sure you could do 90% or > but... you'll wouldn't see a darn bit of your color... unless you like "washed out", hahahah

Finally, I do not know exactly what happens when you "stack" filters... in terms of the transmission. Does it get sliced in half? Or is it worse than that? Hmm. Whatever the case, I would say try to pick a single filter (wherever possible) over two of 'em.

For purple--I will agree with most people I've spoken with with experience... *USUALLY* you're better off doing R_B on an RGB...

Heck, the RGB Grayven made for me looks pretty darn bright for ALL the colors... although sure, a P4 for yellow would probably be better. But likely only for yellow... or maybe sky blue. MAYBE. :)

[Braxus]

sorry guys but i just cant figure this out. how do i order the Lee Filters? i went on the website, registered, found the color i wanted but i dont see link to buy it.

any help?

[xl97]

usually you can just 'order' a free smaple swatch book with MANY options in it..

I think I got 4..

oh... ok i think i understand. you can use the swatches AS the filters? ill request the book then.

thanks bud :)

[Obi-Dar Ke-Gnomie]

Here's a page that shows what the swatch book looks like:

http://www.leefilters.com/lighting/products/range/ref:I46C9C0C1B557F/

The swatches are about 3" by 1.5". If you cut carefully, you could probably get three 1" filters out of each swatch.

[Novastar]

if anyone has noticed too... you hardly need to be TOTALLY perfect with filter.

And even if you screw it all up... you could just order another swatch. If you can't do it twice through the same address... ask your buddy Tom **** or Harry, no big whoop. :)

thanx man it did help

[xl97]

man, evytime I see it.. I just love the P4 white.. NO FILTER!

[Obi-Dar Ke-Gnomie]

I like it like that too.

I'd like to try some of the paler filters to see if I can get a silver/white with just a hint of color. Might make a cool effect. I'll try it and post pictures.

[xl97]

I have a bunch of filters.. (not just LEES) when I was looking for LEE filters I found osm eother places .. Apollo & Rosco sent out some freebies as well..and 1 or two other companies I cant recall off hand.. (just an FYI) ;)

not sure if they make a difference..but I sure do have a crap load of free swatch books..LOL

[DarthFender]

sweet thanx, i do have the swatchbook from lee fliters.:D


How would one go about getting a swatch book for Lee Filters?

[Novastar]

Dang you guys. Does everything ALWAYS have to be spelled out in Latin and Greek? :)

http://www.leefilters.com/lighting/contact/

heheheh

[xl97]

Other places do the same thing.. (send out fred swatch books of their filters)

Apollo & Roscolux do the same things.. just for an FYI..
