Royal Blue Cree XP-G3 CopperNova
We calculate this LED to be about 35% brighter than the XP-E2 with both at 1A and about 160% brighter than the XP-E2 at 2A
Cree Part# XPGDRY-L1-0000-00601
730mW Minimum Radiant Flux @ 350mA
Forward Voltage @1000mA = 3.14v
Forward Voltage @2000mA = 3.45v
Cree XP-G2 mounted on a SinkPAD-ll copper star providing a direct thermal path between the LED and Star.
Conventional MCPCB has a Thermal Conductivity of 1-4 W/m.k. VS 385.0 W/m.K for the SinkPAD star.
Benefits of SinkPad copper star.

Benefits of SinkPad copper star.
- Higher Thermal Transfer Rate (385 W/m.k. heat transfer rate)
- Lowest Thermal resistance
- Lower LED Junction Temperature
- Longer LED life
- Direct thermal path
- Enables to drive LED harder. i.e. more lumens per LED
Much Brighter
I compared it with another lightsaber that has an older royal blue LED, and there was a very noticable difference. It very well could be about twice as bright. I could even see a glow around the blade (not as much as the movies, but the glow was noticable). I think it's well worth the extra power. I used the 0.2 ohm 1w resistor and the 0.3 ohm 1w resistor in parallel to run the LED at the full 2 amps.
