Very interesting, tbh i have not got any of the latest LED's pretty much because i am yet to hear anything positive. I would simply rather have 10,000lm of nice CT over 20,000 of blue/green/yellow. As much as I like high output, beam pattern ,CT and tint are far more important for me. Most of us can get by with far less than a 1000lm, why have crazy amounts but not easy on the eye. All subjective and we all have different wants and needs granted, maybe i have got too fussy! But once you have been spoiled by xpl HI 4000k or 219b 4000/4500k..............its hard for me to put up with anything not as easy on the eye................even if twice as bright(dont care).
Out of the "newer" LED's, its only the xp-g3 i have had experience with.................far from impressed. Yet the xp-g2 4000k and 5000k still today hold their own IMO.
Yellow i can cope with easy(not too yellow though!), blue, green no matter what is a no no for me. As much as i want to light up everything ahead, there is no point if i dont like looking at what is illuminated. Has to be easy or true to life or for me pointless. Guess i am trying to say, give me 100lm of accurate colours over 500lm of washed out faded colours(subjective as its not everyone's priority).
