spring bypass is it worth doing on this light? anyone done that?
Interested in the 219c version.
Lexel did it on his review light. I can’t remember if he measured an improvement or not. Worth checking out.
Yes Astrolux tend to use copper for the head of their flashlights but a MF-01 with a copper head will be much heavier and this will also increase the price significantly. Not worth the price if they don’t push the high and turbo modes to higher current (with higher gauge wires to the LED banks).
it was documented that spring bypasses can gain almost an extra amp on turbo
Make sure to do all 5 springs. I’m guessing it’s the one on the driver that benefits most.
I’m not even sure he bypassed the 4 battery springs. Hmmm?
Hmm he did the current testing without the battery carrier actually. The driver spring would definitely yield the largest gain. I wish I could test differences, but I don’t have the equipment.
No, he used the carrier. He just modded it so that all the power went through an additional loop of wire so he could use his Uni-T UT210E amp meter. It’s the same model lots of blf’ers use, including myself. It’s only about $25 to $30. Having one really helps you to understand current flow and how it relates to output. If you like doing mods and stuff, you should consider getting one. It’s also a DMM in case you don’t already have one.
Beam shot of the MF-01 (Nichia version). Love the tint.

Thanks for sharing Bruno28. One question, how come it doesn’t capture its SS bezel temperature?

You’re welcome.
Metal surfaces that are shiny can’t get the proper thermal reading. Infra red is reflected from other objects around and then the camera captures this.
The same happens with glass and mirrors.
As some have pointed out, the best way to get accurate reading on shinny surfaces is to use a black electrical tape, so the heat from the source will heat the tape and be able to read the temperature correctly.
The red hot areas on the bezel is actually a reflection of myself.
With some additional fins I think still compact enough.
Maybe they could extend the height of the head by adding one more fin. That should add about 6mm which could be added to the shelf thickness. The extra mass would help reduce led temps, at least for a while.
Please put me on the second list for a Nichia. Thanks.
Hi.
My 219C arrived today.
Works as promised, no problems.
Very nice light.
Thanks freeme
i might do spring bypass.
Ceiling bounce test shows 30% more Lux compared to my MT03 hmmm looking good both using freshly charged 30Q.
Well, it’s 9k to 12k. 30% sounds about right. Were you just confirming this for our sake?
not sure what you are getting at, is there something wrong with sharing my own finding here?
MT03 is known not making true 9K lumens, i am just giving a reference here as to how bright the light is. I think the MF01 Nichia is not making 11K lumens from the figure i got. I does look brighter to the eyes though.
btw. Did the test again now i only get only 15% (650 vs 750 Lux) with slightly used batteries (4.09v) Currently charging the battery to see if my initial reading was an error or the full battery did gave higher result
You just seemed to say something random. I was confused.
The MF01 nichia version is only about 7,000. Way less than the xp-g3 version.
I thought the MT03 really did 9k lumen.
sorry if the posts seems random and confusing.
i think the MF01 nichia is making more than 7000 Lumens but i have no way of measuring the exact figure myself it looks brighter than my MT03 and the Lux support this.
If I’m not mistaken, there is only one person reporting about 7000 lumens for the Nichia version. So I hope rizky’s measurement is more representative.
