Still waiting to receive mine!If no one till then has done so, i will!:wave:
You won't see it on the M20 - it's specific for quad-die lights like the Cree MC-E or SSC P7 (or earlier generation Luxeon V).I noticed in the initial review from selfbuilt mention of a 'donut hole' effect - can someone explain to me, other than the obvious, what this refers to? Is this simply a small 'hole' in the spot? I started noticing that with mine just yesterday - can't see it 10 feet in front of me, but if I shine the beam on the sidewalk or road out 50, 100 feet or more I can see it slightly. Can't see it if shining the light in a tree (not that I shine the light in a tree that often.):laughing:
Don't see that on my M20.
Hello, ergotelis.
any news on this, yet?
Is that the M30 also in the last unlabled photo?
Beachman, sorry I was not clear, I meant the last of the beam shots. The one after the labled M30 and before the forest shot.
If only it had a more efficient circuit in medium/low without pwm... Then it would be the perfect flashlight!
While it's true the M30 seems to have some efficiency problems on the lower outputs compared to the competition, I agree this may not be an issue for most. It is still plenty bright for a good length of time (i.e. 9 hours on 18650 on Med), and there is always Low mode to switch for even greater runtime. This is a key point - most of the competition can't go as low as the M30 (although the M1X can go even lower).Selfbuilt's runtime graph doesn't faze me. The human eye is not that sensitive to changes in output. Unless I did a side by side test, I don't think I'd notice the difference in output for the first 45 minutes. And the M30 is still fairly bright (~250L) at the 1:30 hour mark, that's about when I would change batteries if I were using it on high.
Thanks for the beamshots and perspective. These new MC-E lights are definitely pretty impressive.The right of the building is what the whole building looked like, light-wise: you can see the text and that there are windows but nothing clearer. The M30 just lights it up!
This light is fantastic, my neighbor was a little shocked at how bright the M30 was compared to his huge plastic Everyready 6V P.O.S.
Not only does it light up the night, the beam looks very cool coming out of the light!
The last of the runtimes has just been added, finally did the 4xCR123A (Duracell):
(hit your browser re-load button if you don't see it).
Interesting that the time to 50% is the same, but light now exhibits a full regulation pattern (and hence has more output for a longer time). Goes to show you why you need to look at the graphs and not just rely on one time point, like time to 50%.
I haven't done 4xCR123A runtimes on the other other MC-E lights yet (these Duracells are rather expensive ). But the M30 on Max was one of the best performers on 3xCR123A, so I imagine that pattern will hold.
A pity that the efficiency of the M30 Med mode is lower than the competition. Based on RCR results posted earlier, it seems like the continuously-variable JetBeam M1X is at least 2.5X more efficient when matched to the same output. And of course, current-controlled lights like the Lumapower MVP are far more efficient than PWM-based lights at these drive levels.
