Quick Comparison LEDs

Here's a few pictures of my greenies...

From Top to Bottom:

Seoul P4 - Driven @ 1.1A (CF)

Luxeon V - Driven @ 1A (corbin driver)

RGB LED string - Driven @ 1A (corbin driver. 50 LEDs, 20mA per LED)

Which do you think is brighter the seoul or the luxV? I have a green V, a CF4 and a 7.2v 2700ma pack would love to up my runtime if the brightness is comparable (as it seems to be in your pics). The seoul would run for over 4 hours!

And I'm noticing that the seoul blade is a bit longer and still holding it's brightness. I remember x-wing saying that the seoul green was not good, so if yours is, where did you get it?

Curious as to whether or not the Seoul is a "true" green or if it is white with a filter...

Both the P4 and Lux V are using ultra blades. And in person, the P4 is brighter.

This is the green P4, the same one advertised as 180+ lumens. I bought it from led-tech.de

This was more to demonstrate the potential of the LED strings. The other two were just used as benchmarks to test against.
