I am Interested in XHP70.2.
Done.
Just got my MT09R NW, first impression, the light looks good from couple feet away. Closer look, lots of minor XxXxXx. Most obvious, a fingerprint etched on the inside of the len, no matter how i washed it, water, detergent, eyeglass cleaner, it just won’t go away, like some kind of permanent watermark. Then there is a ding on the reflector, small but visible, plus several scratch marks here and there on the reflector. Also the 4 battery spring bypass, 2 has good solder while the other 2 barely has solder on it.
Luckily all 3 emitters centered and function well (knock on wood).
Spring bypass? I thought springs are not factory-bypassed on the MT09R V2 and some guys warned to do that as Haikelite did not follow Texas_Ace’s recommendations and used a very cheap R800 FET instead of the recommended SIR800 FET.
I believe the factory lights have a bypass on the driver spring only. This is the most important spring as all the battery power goes through this one spring.
Mine came everywhere with double springs.
In your second pic, the 2 pegs that hold into the light to screw the tail cap in, does your guys fall off??? One of mine does…i have to pop it in.
Who was that person that got one with a factory bypass and it was done poorly so he re-did it? His pictures didn’t show up so I had to edit them. Maybe that was an older light. Or I might be thinking of TA’s lights. Honestly these MT09R are so confusing. There are so many versions.
If yours came with double springs everywhere, then that is correct. Don’t listen to me. Lol
No problem with them.
They were soldered in well. I put the grease in the tailcap. They came dry. Maybe some grease will help with yours not breaking again.
I prob need to do that…its hard to screw on with batteries in it. Thanks man
The old Klarus G30 has same pins and they did broke if you don’t greased the pcb back. I reminded it and that greasing was one of my first things to do with this light too.
It is possible that they used bypasses at first as they thought it would be cheaper. I kept telling them to do double springs but they didn’t seem to listen at first. My guess is that after doing a few they realized that the labor was going to cost more then double springs and be less reliable.
The good news is that any lights with bypasses should be the early ones if this is the case and thus they should have drivers made with the components I sent them that includes the correct FET.
If you get a picture of the FET we should be able to tell for sure. I know they have 100 drivers with all the correct parts floating around.
We (german TLF) have a Sample in a Passaround. It has a green driver board an a bypass only on the main spring. I have made pictures of the FET, but they are now only on my camera, I have had no time to report my impressions and mesurements. I think only 2 legs of the triangle has the same length.
It looks more as on @Lexels pictures ([♛ FreemeGB] Haikelite MT09R 3x XHP70.2 25,000lm & 3x XHP35 Hi 6500LM Flashlight Group Buy -【 ACTIVE 】 - #280 by Lexel) and the double S looks more like a S and not like a 8 as on the fake FET. And the last line begins with a W.

Yeah, that is not one of mine for sure, I learned long ago to not do bypasses like that. This is what I was worried about when they said they would start doing bypasses.
My guess is that one also has the good FET.
I made a big plastic washer for the whole tailcap out of some food container. The step in the cap cut into the solder.
Got mine. 
I have the one with doubled springs.
Remember that you don’t need to screw it all the way down. Just enough to cover the rubber seals.
Yes, this is the style I was thinking of with the bypass on the outside. The person changed it to an inner mounted bypass. It’s good to know I haven’t lost my mind. LOL
Is there a writeup of tips for doing proper bypasses? I don’t know if you want to keep your techniques secret, but I’d like to hear them if you’re willing to share. :+1:
Now this may sound stupid to some of you, but what’s even a good way to hold the wire in place until it’s soldered?
Fine tweezers is what I use. A set of them is cheap online. They are good for holding smd components as well.
Are you asking for soldering tutorials or advanced solder tutorials? Youtube is full of that stuff.
