maukka could you do a review on the mf02s testing lumens and cd?

Yes, I’ll review it. Probably finish it some time next week.

code for cw MF02S please

Would you have an estimate on what the battery amperage should be for each cell?

I think the MF01 was 8A per cell. I’m guessing the MF02S and MF04S are about 9A per cell? Does that sound about right to you?

I doubt it, lexel says his buck driver drives the xhp70.2 at 6A and that gets over 7,000lms, the stock mf02s factory claims 6,000lm

That’s at the emitter, though and through a buck driver using the cells in 4S and I kind of doubt it’s doing 7,000 lumen at 6A@12v. (That’s 12A@6v) I’m sure the draw at the batteries is higher than 6A each. At least 7A maybe.

The MF01 boost driver drew about 16A through a 2S2P carrier for about 120w. Let me think, if we just used the 2S cells and it pulled 16A, then that’s 16A each. If we add 2 more in parallel then that should halve the load to about 8A each. Yeah, we are still about 120w.

The MF02S and MF04S use the same boost driver, but with a different sense resistor to increase the output. So maybe 130w. I would say each cell is drawing about 8.5A.

It would just be nice to get some confirmation. I’ll probably have to wait till his review is up.

Awesome! Matte looks nice but grease stains are harder to remove. Slightly glossier finishing should solve this problem. All Astrolux MF series lights will be updated with this new button design.

Code please for the MFO2S thanks we

Please send code for MF02S NW. Thanks.

Toglud.

You got mail.

Threads glued?

I have ordered the MF02S in neutral white.
Thanks for the groupbuy.

Just ordered MFO2S thanks. What are the best batteries thanks again

Samsung 30q, Sony VTC6, NCR18650 Ga

The GA are not high drain.

I would stick with high drain cells like Samsung 30q, Sony VTC6 or VTC5D.

You’re right. I thought 10A discharge current was enough

Yeah.

MF02: almost every cell like the NCR18650B can be used, since it doesn’t require more than 3A per cell.

MF02S: High drain cells are preferred. I would recommend using a low resistance 15-20A rated cell like the Samsung 30Q, Sony VTC6, Samsung 25R, LG HG2, or the Sanyo UR18650NSX if you can find one.

It’s more about the voltage sag. The high drain will let you run turbo for longer. Here is a chart at 5A.

The only real advantage to the high capacity cells comes at the lower voltage levels.

The Panny B is an old cell. It has noticably worse voltage sag compared to newer cells like the GA. Even at low amp levels like 1A and 3A as shown here.

I don’t even buy the B’s anymore. For high capacity use, I would say the GA, 35E and MJ1 are the best choices.

+1

I’m just saying that it is safe to use in light like the MF02.

Not in a light like the MF02S.

Personally though, if I was buying new cells, I would just buy Samsung 30Qs and the like.

Best all around cell in terms of capacity and current delivery.
