ASTROLUX said that it has been manufactured in batches, and will be on sale in the middle of next month.
Please add me to the GB list. Thank you.
Yeah, I got the light to behave thermally, so I think it should be almost ready to buy. Here’s an example of a thermal test with the maximum temperature set pretty low to make things harder for the thermal algorithm:
Given the style of power channels used, this result is pretty close to optimal.
Which emitter is it using? The sustainable lumens seems low if it is xpl hi or sst 20 70cri. The heat shedding of this version is significantly improved by TA from the original MF01 so should do better than this.
Seems kinda disappointing tbh. Efficiency could be better. It’s set to only 45 degrees so I guess it could sustain higher output.
It’s probably using the SST-20 95CRI emitter, as it seems inefficient.
I think this is SST-20 4000K 95CRI, which runs hotter and less bright than the lower-CRI versions. Just checked again, and it’s definitely around 4000K, so it’s not the 5000K 70CRI version.
Yes, you should have the 4000k FD2 bin LED’s if they did as I asked lol.
This high-CRI version is only supposed to make about 10,000 or 11,000 lumens, but I measured it at 13,900 lm at start with a set of just-charged 30Q cells.
This was measured with an integrating tube, so it’s not as accurate as a sphere… but it’s pretty close. I used some biased diffuser sheets to improve the integration qualities, then calibrated it to match reference lights from maukka. The sheets force the light to spread out and bounce around inside, so it’s less favorable to throwy lights. It also acts as sort of like one-way valves, which reduces the impact of the entry point and initial bend, so it gets more consistent readings for a wider variety of lights. But it’s still not as good as a sphere.
Anyway, I think it actually could make 14,000 lumens with some high-amp cells like 25R. And more, when using lower-CRI emitters. Just not for very long, because it gets hot fast.
All the technology in today’s world and astrolux uses a camera from the late 1990s.
What are you refering to?
The last post on page 12
Nothing shows up for me, but the coding says it’s an animated gif, not a picture. Typically gifs are grainy so that must be what your refering to.
TK, will the first batch of lights get updated with your improved thermal regulation firmware?
I don’t have any details on that. I hadn’t even heard there was a first batch.
Im referring to the yet to be on the market first batch that is supposedly already in production.
but looking at the graph it shows at around 2m its already down to 2000 lumens only ? kinda low to me…
Only the metal parts are in production at this point last I heard. The driver and firmware have yet to be finalized. Could be wrong though.
This Astrolux MF01S looks very similar to the Emisar D18, as both use 18x SST20 emitters, and both use Anduril firmware.
Just curious what would be different about this MF01S compared to the Emisar D18? The D18 uses 3x18650, so the batteries have to work harder to put out higher lumens (need to use very high-drain 18650s on the D18), whereas the MF01S uses 4x18650 so the current drain per battery is notably less. (I’m assuming that the higher max lumens on the MF01S compared to the D18 is mainly due to the MF01S having 1 more battery to drain current from).
I would presume the MF01S, having a 4x18650 body, may have a bit more thermal mass so heat may be able to dissipate a bit better — at around what lumens does the MF01S stabilize (it seems to be nearly 2000 lumens from the above graphs), doesn’t the D18 also stabilize at nearly 2000 lumens?
How about in terms of beam pattern, I’m curious how the MF01S compares to the D18 (the D18 has a focused spot, corona and useful spill area of light).
