Is it still the original firmware with all the bugs or was it updated? I was really interested in this light and followed the project closely until the flashlight was released. But Inferion wasn’t able to provide the final firmware in time for the release, so he wrote a quick replacement without the originally planned features and without much testing.
Chinese generic (zebralight clone) host with BAD thermal patch and Russian “eficient” linear driver only for you and only for 50$ shipped.( yes , yes i love YLP )
Well, I’ve dissasembled my Gekko after reading about bad thermal design and see what I saw. Nice, right? Almost no conductivity to body. Plus copper plate is attached to 1 mm plate in the head (the one you see with screw holes is not body, it is thin plate inside), without direct contact with cooling ribs outside.
I changed glue to good thermal compound. To my personal feeling - heating changed to faster and hotter, means better thermal conductivity.
Changing compound makes thermal exchange much better, actually. The only question - why can't put good compound from factory, since it is the cheapest part of all the product, and emitter is attached with screwes. No need any glue here.
All the rest - it is pretty good flashlight. Light, waterproofed, and convenient hi-cri (to my opinion).
I use mine pretty often, so far works fine, when it cooks its own led, then will take it apart and play with it, maybe even fix it, or i’ll test my aim at 100 yards with my .44mag lever action.
It IS a shame, they went thru all those troubles to design and manufacture pretty decent light, even if their driver is not most efficient or advance, but all of it seems to be negated by simple “saving by a shortcut”, simple QC and maybe an extra step to ensure proper heat path would make this light actually reliable in a long run. go figure,
It is exactly what I mean - so much effort to design and manufacture, and such a poor QC. Even the cheapest Convoy has more and better compound. I spent 8 years in China working in trading and QC of our orders. It is so simple to hire an expat there and let him/her check every 20-30th unit or even less frequent. Even simple presence of "inspector" helps a lot )))
And where did the heat go with bad thermal compound?) It’s just self-suggestion. The only difference is led temperatuture and corresponding decreasing of luminosity while led warm up, and you can not see it without instruments.
This is a wrong question. Not where, but how. Heat dissipation affects emitter lifetime. I'm not going to discuss it, just wanted to let others know about this issue. And I posted same at fonarevka, if you're interested http://forum.fonarevka.ru/showthread.php?t=45417&page=34
It is right question. You just not qute understand phisics of this process. I am not interesting in your subjective feelings, thanks, I have thermal camera and I can measure everything that can be interesting.
I also not going to discuss that. I just let other to know that you subjective feelings of issue deviate from reality.
Not posting it for you personally, so I don't care what you're interested. Don't know why you protect YLP that much, even cheapest Convoy has better compound in it. Other than this - Gekko is nice flashlight.
My initial post is to show people what they buy before they buy it. I would appreciate if I saw it from someone before I bought my unit. By the way, the comment on vk page of ylp says they plan to release second batch of Gekko - same design, but updated firmware. I'm curious if they change something inside too. We'll see, I may buy one just our of curiosity to see what's new.
