Oh No! (Fixed)

Somebody help me figure out what’s wrong with my Blf A6. Noticed my lens starting to look a little foggy and there’s a black spot on my led. I normally turn the light off when it gets a little warm. Hope it’s not something I did. Still functions fine.

Update: replaced the star with led pre flowed because I’m a wuss. It was my first time doing anything like that. I know it’s stupid simple but still felt good when it worked thanks for your help. First baby step taken.

If you shine the beam on wall can you see the dark spot?

Can see a dark spot on a white wall. it wouldn’t be all that noticeable to you average joe.

Insufficient thermal paste or ran too hot > LED and MCPCB overheats > Remaining solder paste or flux on the board is evaporated causing the fogging.

A small dark dots on the emitter surface normally means too much current or needs better heat sinking, sometimes it can be cleaned with some alcohol. (When it happens in a HI)

I would take the light apart and check for lack of thermal paste or bad reflowing job. Then run the light on turbo until it gets hot before assembling. I have seen soldering paste remains evaporating many times and fogging up the reflector, specially on the SMO ones.

How do I upload a pic from my phone on here?

A-6’s have a tendency to de-dome when opened. just a heads up.

Could just be flux and you can wipe it of easy?
You need to upload the photo to Flickr or another sharing website and then post the share link here.
So grab the photo sharing url and click the photo icon here and past the url where It goes in the box.

Took it all apart and the dome is melted / burned in that spot. Dang it!

Everydaysurvivalgear ive watched most of your videos on YouTube!

can you slice the dome off?

! !

Sliced the dome off now the light will not turn on. What did I do!?

Could be a burned in speck of dirt.

Thanks mate!

You could have nicked the bonding wires under the dome? Its a goner if the bonding wires are broken.

I’m sure I did how would I know?

There is no help for this.

Swap emitter and you are ready to go.

Take a pic for us? Can you see any small wires?

The wire will look like this. I think the XPL only has bonding wires. Its the small wires inside the LED

I mourn the loss of my favorite flashlight. Glad I have a second one in a warmer tint that I just discovered I like better. Now I have my first emitter swap to do. I feel like a idiot but the hard way is the only way I learn unfortunately.

Welcome to Modification 101!

Thanks haha. I have some equipment to buy and some reading to do.
