The replacement MT01 finally arrived from Haikelite. Not sure if any one else found that most regular non-protected 18650s are still to long for the battery tube in this model, but after cutting off the springs & adding three tiny brass washers to the back PCB to make the battery tubes long enough to work with 18650 cells, the replacement works great.
UPDATE A THE BOTTOM OF OP: ( March,26,2018)
So i bought the MT01 back in August from a GB coupon post here & it arrived with flickering issues. I managed to fix that due to a bad cold-solder on the driver. it worked fine for another couple months, (very little use) and in December i noticed it was dimmer, and had a weird artifact in the hot-spot. I discovered half of the XHP50.2 LED is dead… (two of the four dies of the XHP50.2 on one side of the emitter does not light up.) :FACEPALM:
I checked the LED board, and everything is good there, but the emitter is just half dead. Should i try contacting Banggood or Hakilite on this?
* Update: - Dale from Haikelite contacted me via DM, and is working to offer to fix this issue i have with my MT01. (will post updates here on it when i hear back & on what they do for me.
* Update, March,1,2018 - I am still waiting for Haikelite to fix this issues, still nothing.
* UPDATE, March.25,2018 - So its been past 2 months now with a useless dead, failed MT01 i purchased not long ago, and Haikelite did NOTHING to fix my issue, all they did is give me the run-around, claiming this ” Dale ” person was supposed to contact me, (of whom never did after months ago,) and they kept delaying any fix for the faulty MT01 i bought from them through Banggood. As mentioned above, the XHP50.2 emitter burned out two of its four dies, then the light stopped working completely not long after. I tried another emitter, (a new XHP70 i had) but the light failed to turn on at all, so i guess the driver failed too??
Either way, the months passed and i still have a dead MT01 taken apart in a box that is basically junk. The last message that HaikeLite Official here on BLF sent me 2 days ago was: ” Could you please provide your banggood order number and email address? We send the XHP50.2 emitter with MCPCB to banggood, They will arrange the shipping to you” … REALLY?!
all they needed to do months ago is send me the parts directly or a replacement light, but NO, they come up with that idea? SO i have red-flagged Haikelite as a flashlight company with POOR to ZERO customer service. I will never buy another light from them, and will never recommend Haikelite to anyone, as if their light fails, they will likely get the shaft & BS that i did. I have had far better customer service from other established brands of lights i had an failure with before. Olight, Thorfire, Manker light, all have great customer service and will help their customers quickly, Haikelite will not. They claim they want to build great lights and succeed as a flashlight company? well they better fix their horrible lacking customer service first before i will ever buy again.
*UPDATE, March,26,2018 - Haikelite USA have read my upset and distaste for the delays and poor service on my dead MT01, so the last message they said they will ship a replacement light tomorrow. (unsure from where or how long it will take, but lets see if they live up to their promise this time, and will wait up to another month to see if i receive anything. I will post here again with an update once i do.
