I put a Banggood FET driver in my BLF X6 and after turning it on after assembly it flashed brightly but only momentarily. Hummmm not a good sign I thought. It then refused to turn on again until I shimmed the driver ring slightly with a piece of wire. Now it lights up but a) not real bright, b) has a ghastly bluish hot spot on “turbo”, and c) 1/2 of the led is dark when looking at it on moonlight.
No doubt I cooked the Led but the X6 has a DTP board, right? And it was only on for a second before it went off the first time so there wouldn’t be enough time for it to overhead? It’s possible I touched the led with my soldering iron but I don’t see any signs of damage.
If it really does have a DTP board perhaps I’ll try to reflow another led onto it. I’ve never done it before and this might be a good time to start. If so do I really need solder paste or can I make do with solder? It’s expensive to buy soldering paste for just a single led.
What battery did you use, you can also pull the star and try in another regulated light
The blue suggests you did fry the LED, it could have been defective, or the driver is somehow?
Sometimes they forget the solder under the heat pad, while rare it has been posted about before
The X6 was working fine but I decided on a driver upgrade
I was using a Samsung 30Q but I also ran the head using a 3.3v power supply. To me the dark portion of the led tells me I killed it
I forgot to mention that I was going to install the original X6 driver in a stock Convoy C8 with an aluminum star. Any issues with frying that led? If I recall I was getting 3.5A’s at the tail with the X6 driver.
It was stock when it cratered and I was thinking about reflowing it for the learning experience. But I’d only do it if it was DTP and able to handle the FET driver. Fortunately flashlight mistakes tend to be relatively cheap. Cheaper than throating a 1911 barrel and then going….oops (which fortunately I’ve never done :laughing:
