-so far ETA looks like March-

Max Lumens compared to 3w - Yes the Amber,Red, and Red-Orange have less output.

K2/3W
45/100 Amber
35/30 Blue
100/80 Cyan
100/80 Green
60/140 Red
60/190 Red-Orange
575mW/450mW Royal Blue
120/80 White

White, Green, Cyan, Blue, Royal Blue
max mA 1500
Forward voltage @ 1500mA 3.85v

Red, Red-Orange, Amber
max mA 700 (hence the lower output)
Forward voltage @ 700mA 3.4v

looks like white maybe the brighter of the bunch. could go with that and use the color disks then i guess.

You dont know the POWER, of the dark side...

Any word on whether they will be available in a "star" format, so we can swap out our Lux IIIs? Or, will a new heat-sink mounting be needed?

I'm a little confused. The Royal Blue seems to be on a slightly different measurement. can you explain the difference? Or is it merely there for a ratio?

Oh, and any word on them coming in yet? Last you said was March.

You can buy the emitter form of K2 now.

I did a bit of research. They use mW because that's how they classify the royal blue when they sort them.

Using the luminous efficacy I can figure out the lumens. Luminous efficacy is lm(lumens)/W. From the chart in their spec sheets the dominant wavelength of 455nm of a Royal Blue is about 50. So if 50 = lm/.575W

Do some math and that makes 28.75 lumens. So indeed it proves the royal blue is weaker. I hope I figured that right...[xx(]

Oh brother...[

] Pick the color you like, not the one with the highest lumens.
