ok thank you for the response.
to remove the reflector for blf q8, I just need to unscrew the top portion (silver aluminum ring, o ring , glass) and the reflector can be pulled upwards directly?
or do I need to unscrew the bottom including the driver circuits etc. ?
I’m afraid that you need to go all the way. Everything comes apart fine but this is it:
First unscrew the silver SS ring and remove the glass and large o-ring. Turn the head around.
Unscrew the driver and tilt it until you can get past it with a screwdriver. Inside the driver cavity first unscrew the big central screw then the two small screws. Then the reflector should fall down. Clean the led and reverse for assembly, take care to seat the reflector precisely on the the plastic centering rings around the led before tightening the screws in the driver cavity.
I so love this site.
Always a guru a click away. 
yeah I feel the same here. even though I’m a new member people help me voluntarily with nothing to gain. and it’s especially helpful for a newbie like me who’s worried things go wrong when yall guide me. Thank you.
update: I’ve contacted banggood about it, but they have not responded. most likely it’s a non issue, since I cycled it thrice and nothing has changed. but I’m using protected cells as the new unprotected haven’t arrived.
I’ve also bought another q8 as a spare, as I felt it’s a really good light even with this “defect”, and also since the banggood coupon code might expire soon. Hope that one is ok!
What banggood coupon do you have? I was looking for some type of coupon earlier.
Im using a code from https://m4dm4x.com/blf-q8-arrived/ which gives me about 45% off.
*edited to remove code and include website
I don’t think you are supposed to post that code openly. You need to go to M4D M4X’s website to get the code, and for him to get his commission. (I think)

Nice to see you still have your sense of humor g_sintornillos.
I posted a while back about a dead green indicator LED that was unable to be fixed with soldering. Does anyone have any email addresses or usernames of people I could try to contact to get a replacement assembly?
Try it again with the old mail address. Now Chinese New year is over
Update: I wiped the led as instructed and the “bubble” is gone. Seems like it is just a speck of dirt. Don’t know why it seemed so much like it was inside the dome initially.
On a side note, I accidentally wiped off some of the thermal paste (TIM) while removing the reflector. I used some of my CPU thermal paste (cooler master ic essential E2). Is this fine or do y’all have a preference for thermal paste for flashlights?
thanks for the help everyone
^ although there is much heat to be transfered, the contact surface of the ledboard is large so the thermal paste should not be critical, as long as you keep the layer thin.
