The D1 host is a handy little mini thrower, but its reflector has held it back. The center section of the reflector deviates from parabolicity so itās impossible to completely focus smaller emitters like the 2mm WF or even the stock XPL HI. This results in decreased throw since not all of the reflecting surface is used for the hotspot.
So I put in a sliced XHP50.2. The emitting surface is large enough to get better focus of the reflector. I usually have a hard time deciding what emitter to put in what light (because most of my lights donāt have actual uses, just theoretical uses ). So in this case it was nice to have the decision made easier by the reflector.
With stock springs and a VTC5A it pulled 16A at turn on and did 46kcd at about 5s. From my ceiling bounce I estimate 3300 lumens.
Edit: in fact partly because of the better utilization of the reflector area, this mod about equals the throw of the stock XPL HI, but with 3x the lumens. :laughing:
Pretty vintage led now . but i still prefer it to the Bill Gates summoning Xhp70.2, im not sure what the lumen count is at 5 amps but it certainly lights a nice area
I still have multiple lights with MT-G2, including a triple that I built from scratch. Love the tint this big emitter makes and surprisingly enough it can have a nice beam profile in the right reflector. Also have an old BTU Shocker that I fitted with MT-G2ās, in this light there is a defined hot spot that is surprisingly smallā¦ really do love em!
Edit: Was forgetting about the massive TrustFire TR-J20 that I built a huge heat sink for and fitted with 4 MT-G2āsā¦ itās making almost 15,000 lumens while the other two big ones are in the 10,000 to 12,000 range. Yup, really do love the MT-G2 and like seeing it being put to use.
Edit II:
I have 19 MT-G2ās in use, in (I think) 12 flashlights. Probably forgetting somethingā¦
Very nice work, I bet they really kick it out!! I like the 5k 80cri it really isnt far behind the xhp70 when driven hard but the tint is just so much nicer almost like real daylight
I have the MT-G2 in a lot of very different lights, such as the Nitecore TM-03, a 2D Maglite with a fiber optic battery indicator, a Lucky Sun D80, Solarforce K3, S2200, M8, and C2000 , as well as my DBC-05 triple, the BTU Shocker, and the TR-J20. Also have a hybrid TIR over an MT-G2 in an L6. And of course, I have an X6 with the fat MT-G2 and an extension tube.
One of the major differences is the array status of the big emitter, itās almost like a COB really. So the quality of the light is due to the 72 small die surfaces most likely. When I was building the M8 I didnāt have a suitable driver back then so I ran it literally direct drive, it would pull just over 16A at about 4300 lumens. Ah, the good ol days! lol
Probably funny questions, but Iām still too young here.
I have this flashlight disassembled for a long time because I donāt know how to do heat dissipation well. Do you have any great solution or did you leave it as is?
I was one of the team on the X6 group buy, there were a few extension tubes made for the team. They missed the length but I have worked around thatā¦ interestingly enough that was another Neal failure, not only was the length wrong but the MT-G2ās he sent for me to build team lights were also wrongā¦ he sent 9V instead of 6V MT-G2ās.
