✌ FREEME - ASTROLUX MF01S 15000lm Flashlight Group Buy - ENDED

All the technology in today’s world and astrolux uses a camera from the late 1990s.

What are you refering to?

Interested!

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).

Keep in mind that the D18 was 70CRI LED’s and the MF01S above is 90+CRI. So the lumens will be lower naturally.

The D18 is available with 4 different emitters 2 of which are 95 CRI

Led & Tint
Cool White - SST20 6500K
Neutral White - SST20 5000K
Neutral White - SST20 4000K 95CRI
Warm White - SST20 3000K 95CRI

I think TA meant the D18 sustained output was tested with 70CRI emitters whereas TK tested the MF01 with 95CRI emitters so you can’t directly compare these sustained outputs.

with the firmware you can calibrate the temperature and set the ceiling higher

This was not a test for highest sustainable lumens. This was a software test of how the driver handles heat. Two different things. So I would not make assumptions.

To test max sustainable lumens you start at a certain lower lumen level and see how the light behaves. Temperature will build up much slower which may or may not activate the thermal management and you should get different results.

It will probably be in the same 2,000 to 3,000 range, but probably higher than what the tests above show.

My point is you should not jump to conclusions. Recognize what is actually being tested. (I might be grumpy today)

They’re a similar concept, but there’s a significant difference in size, beam shape, driver type, and extras. The MF01S is larger/heavier and holds 4 batteries in a carrier instead of 3 in the tube. The MF01S has a big wide “wall of light” hotspot with virtually no spill, similar to a Noctigon Meteor or a triple in a Carclo 10507 optic. It uses a 2S2P 2-channel driver at 6V instead of a 4P 3-channel driver at 3V. It also has colorful aux LEDs and a lighted button and a tripod mount hole.

I’m the wrong person to ask about which is better though, since I mostly stick to smaller lights.

Hopefully I wasnt getting my hopes up over this. Im pretty much sold on a D18, but the driver and the aux board on this were definitely interesting. Im surprised it doesnt really show much difference over the D18’s specs considering its size and assumed increased driver efficiencies.

The drivers themselves are basically a wash on paper. The D18 should be a bit more efficient at lower modes and the MF01S a bit more efficient at higher modes.

I expect the optic efficiency to be larger then the drivers.

Interested, pending price.
