Seoul P4 lumens

[Darth Cruor]

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

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

Wow. Lotta lumens on that.

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?
