Yes, I was debating between MT02 and SC01, but on paper the MT02 had more throw, so that’s what I went with. Also, I don’t currently own any 26650 batteries, so that would have been an additional expense if I had gone with SC01.
No big deal. I will just wait for it to arrive. I’m hoping I will still like it. I currently don’t own any lights with more than 1,000 lumen output, and none of them are super throwy, so this MT02 light might still be a significant improvement for me.
I made it myself, it uses Arduino nano v3, BH1750 sensor and 0.96in OLED display. Not the prettiest but gives results
You can also use your mobile phone, with almost similar result, i dont have dedicated Lux meter.
Got my MT02 today. I love the silver finish. The beam pattern is a bit rough, but I have not had a chance to take it outside yet at night to see what it can do.
This actually worked, just barely. The screws are quite short, so you can only accomodate a very thin washer, but it was just barely enough to allow me to squeeze some NCR18650B protected batteries in there.
Cheers man! I ordered the silver MT02 from Banggood as well. Hopefully within a week I’ll have mine. Less than $40 for such a beauty, haha! It’s my first Haikelite, so I’m stoked alright. :sunglasses:
And thanks for the recently uploaded videos rizky_p on youtube; I checked them all out. :+1:
A single 30Q is about three times more powerful than a single NCR18650B, so technically you should be able to power the light with just one cell. But it’s straining the cell quite a bit.
I’m not too familiar with driver design, so I don’t know whether it will influence output. If there is a difference in output, then two 30Qs should be brighter than three protected NCR18650B. Haikelite advises three unprotected NCR18650GA, and maybe three NCR18650B could be insufficient.
Anyhow, two 30Q should be no problem, as long as they have a button top or solder blob for contact.
I have a few more side-by-side shots incoming if you interested there all uploaded but still in private including MT03 but i will release it along with my MT03 review. I also have Haikelite MT01(silver) sample by Banggood incoming and probably arrived on Monday so more side-by-side video along with it.
btw I am more interested in receiving my emisar D4 though hahahaha also on Monday.
Nice photo Pete7874. i wish i had the gear and skills to take awesome picture like that.
Should not be a problem i think As hIKARInoob said 30Q is more powerful, i tried running it with single Panasonic 18650B and it is doing that “ramp-down and up” stuff it is like the voltage sags a lot. I also run my MT02 with 3xNCR18650B,
BTW my flat-top Samsung 30Q doesnt make contact without solder blob, and it damaged the wrapping slightly because of the circular motion.
I havent tried unsoldered NCR18650B since all mine are soldered-blob already
Thanks. I’ve got some 30q button tops on the way for this light.
I walked around with it running two 30q cells last night, and even after 10 mins on turbo, I could still hold it in my hand. Not sure if it would have gotten any hotter running on 3 cells. Outside temp was in the 60s F.
One thing I’ve noticed is that visually there isn’t much difference between high and turbo.
Has anyone been able to measure actual current draw at various modes?
This is the result, but bear in mind since the driver is using boost topology it doesn’t reflect emitter current.
I was using a single Samsung 30Q.
low = 0.19A
mid1 = 0.57A
mid2 = 1.5A
High = 2.8A - 3A
Turbo = 6A(start) 6.15A(few seconds afterwards)
On high and turbo the amp draw steadily climbs this reflect current regulation to the emitter to maintain stable emitters current. in lower mode should be the same but not that visible since the battery doesn’t sags as much.
It is interesting though, with some basic math on turbo with boost driver efficiency of 80% the emitter probably get around 1.4A.
