The MT09R has a much floodier spill than the MF01. The MF01 beam is more focused. I put DC-Fix on my MT09R and the beam is PERFECT. Great flood, good throw, and smooth hotspot transition.
Also I have two MF01. One is stock and the other one is modded by Lexel. The Lexel modded one with buck driver puts out 1615 lux at startup and the stock puts out 1244 lux at startup on fully charged VTC6 batteries. UI on the modded one is idential to the Emisar D4, which is much better than the crappy Astrolux driver. However, lumens decreases rapidly the moment you turn it on similar to the D4. The stock MT09R holds brightness much better than the MF01 but then it is larger and also didn’t have thermal regulation.
Whaaa! I really like the MF01 but too bad it’s UI sucks compared to the Q8.
So you’re saying it has more flood and spill than MF01?! If you have a moment can you (or anyone) do a good shot of how the MT09R lights up the area? Thanks!
The extra throw comes from a combo of the lumens and the reflector size. Even when split up into multiple LED’s the larger the total reflector size, the further the throw as a rule. There are so many more lumens the it is simply brighter everywhere. Although if you turn it down then yes, it would have a bit less flood and a bit more throw then the Q8 as equal outputs.
Yes, the MT03 is the same price as the MT09 as long as the batteries are 2s2p, if they are 4S there is $15 extra labor to convert it.
And here comes another question :person_facepalming:
4S means all battery insert the same direction right….?
Mine is 2 in 2 out so I would assume that’s 2S2P?
Besides the driver swap, an important consideration is whether you’re working on a early version 1 or a later version 2 MF01.
Version 1 has 6 wires going to the leds and uses 6 volts.
Version 2 has 2 wires going to the leds and uses 18 volts.
If it’s version 2 you will have to cut traces on the mcpcb and add some wires to get it to accept 6v. This extra work for version 2 has to be factored in.
There is only one place selling them, IMR Batteries in Houston, and they are $18 each. Shipping was $11 for 2 of them according to DBCUSTOM. So not cheap, at least for right now.
That's a ton of power from even a single cell. May have to wait until next week and I am not seeing a button top so some solder blobs and these should prove to be trying to find somewhere to get my hands on a few dozen.
His FET driver is cheaper and higher power than his buck version. But I chose the buck version because I wanted to be able to maintain the lumens even on non full batteries.
Since I don’t configure the UI, the controls feels the same to me. I like it simple ramping like that.
Led board = mcpcb?
3S = the mcpcb is 3S6P so it needs 9 volts?
So the buck driver is 12v to 9v?
I thought that buck driver was limited to 6A at 12v or 9A at 9v. You are getting 13.5A to the emitters at about 11 actual volts?
