I just got the SureFire G2X Pro. After the very blue tint of my Maglite Mini LED Pro and various cheap Chinese flashlights, the white coloration is far better. I have a halogen 5 MILLION CANDLEPOWER spotlight. I prefer the whitish SureFire to the yellowish-white full-spectrum halogen lighting. BTW the SF costs 5 times as much, is 1/15 the size, and outputs a similar quantity of light for a far longer runtime.
People who grew up on incans often prefer them. Personally, comparing the dirty yellow of classic Maglites, faded old auto headlights, and bargain-bin spotlights to the high-tech blue of cheap LEDs and tinted headlights, I prefer the blue color. The high-end white of my LED SureFire is even better.
Maybe if I see a P61 in person I will think differently, but the idea of a flashlight burning out in the 21st century appalls me, even if it has good color rendition.
