I just got word from BangGood that they are having system issues and the coupon code may not work. If it doesn't don't worry I will post the moment that they say everything is working.
I received my sample today and so far have only tested max turbo output.
I thought some of you waiting would want to know.
I measured 8858 lumen using freshly charged 30q's. I did not have enough time to take a 30 second measurement.
I will have my complete review posted by Saturday evening.
BangGood has provided a discount code and please click the URL. It is not an affiliated URL it only shows BangGood that you got the information from me. I do not earn any money at all only the light.
Do you have the MT03 70 to compare it with? The old one I’ve seen people getting over 9000 (IT’S OVER 9000!!! sorry I just had to lol) and some tested 10k in the CW version. However, your results aren’t bad at all! they met the factory specs is all it matters
Yeah I just did a ceiling bounce test and got higher results.
Lumen levels this high all sorts of things come into play. The sphere I did the initial test in is very strict... I've got a out 80 light's documented through it for calibration so it is usual very close.
I do need to check several things including changing the glass. This light floods a ton so even the edges of the glass it sits on can change things...
That is straight out of the box and a really quick reading. I will have more accurate measurments when the completed review posts.
One of the odd things about this light (tested by Maukka) is that output increases after start-up: HaikeLite MT03 review with measurements (3x XHP70, 4x 18650)
Well it’s a mighty fine looking light, and I sure look forward to the rest of the review. :+1:
You could measure output every 20 seconds after startup and after 1 minute measure every minute for a couple of minutes to see if you get similar behaviour, and to see what, and when max output is.
I have one of these on the way from Gearbest. the coupon Haekelite bring it to $77.
I plan on running 30q batteries or Sony VTC6. Has anybody tested between these two options to compare?
I also have the SC01, SC02 and MT07 lights from Haikelite. Pretty impressive lights at the price points.
1.I have 30Q, VTC6 and Sanyo (10A), to my eyes I can’t tell the difference lol.
All of them are very bright and I’m sure meeting the lumen spec isn’t a problem, it all comes down to the total run time of the battery.
2. The gearbest have the “older” version with 70. And only in CW, I am very happy with that one already. Now I’m waiting for reviews on the differences between 70.2 vs 70
Okay they shipped me a different driver. I started the swap out yesterday and hope to complete it when I get home from work this morning.
I am not yet sure if the driver they shipped to me is the updated one thats held up production or if it just a driver that has corrected the flickering issue. Hopefully I will know in a few more hours.
These are not very swap out friendly. There is just enough wire to reach and no simple way at least that I can find to get through those cut outs on the shelf. I will try to upload photos of both drivers
My patients will be stretched to maxium changing this board.
Looks like the same board, weird they got rid of U5. Looks like the new driver is missing the sense resistor, there should be at least one on each channel. Hope you spotted that before soldering in the new driver.
R4 has been changed for the better. Do you know what the value of C1 is on each driver?
Just got home and checked my notes from my driver. It looks like U5 was one of the three QX9920 buck controllers. The sense resistor connected the two N-fets to ground, the fet side of the resistor went to pin 6 on the Qx9920. If they deleted the QX9920 the sense resistor has no purpose. The fets still need to connect to ground somehow.
The zero ohm resistor where U5 used to be is connecting pin 4 on U2 to the gates of the fets. I think that pin 4 on U2 produced a 31khz pwm signal to control all three buck controllers. That’s probably too slow of a switching frequency for a buck driver, U2 has likely been reprogrammed as well.
Seems like some pretty serious changes, looking forward to seeing the full picture of the new driver.
The model number of the board should be over by C1, mine is S205A3. Do both of your boards have the same numbers?

Just FYI as of yesterday 1/19/18 the code 90656f still works on the 12,000lm $119 MT03. Made the price $95. What a stea…uh, deal! Thank you for the code, as I was now able to get some HG2’s to go along with it. :partying_face:
