Thank you Rdubya18 for the kind words. You are right, I was glad I took my time and did not crush the head tube…
and thank you also NeutralFan
My favorite is the sw45k in the evening (the tint is closer to incandescent), and e21a during the day (the tint is closer to daylight)
the sw45k is an easier mod to get a decent beam, and it is not as green as the E21a. Green is relative, another way to say that is the E21a is less pink, hence closer to daylight, which is greener than incandescent.
E21a makes whiter whites, but sw45k makes juicier reds
the E21a mcpcb is NLA, whereas the sw45k is an easy reflow to the stock mcpcb, in these models that were xpg
even in the xpl models, the sw45k is easier to get a good beam, the E21a sits lower, which is not good for the beam… (the LH351d 5000k dogfart is dedomed, which lowered the cct)
output and weight:
the V10a w AA Alkaline weighs 82 grams and makes 65 initial lumens, the same head on a V11r body w 16340 weighs 65 grams and makes 210 lumens at startup
Both of the V10a have firefly lows below 0.01 lumens on my meter
(I can see they are on, but my light meter reads 0.00)
the stock xpg is 10% brighter than the sw45k
Im new to AA… it is heavier and longer, easier to hold, though personally, Ive always liked smaller things. For me, the smaller and lighter 16340 body is easier to carry.
Im very happy to fill an AA niche with a Rotary… the V10a fits that role nicely.
all things considered… the sw45k is the winner!
