My first emitter swap was a failure…
Brinyte B158, stock with XP-L HI V3. Swapping in XP-L HI V2 5A2 on a Noctigon. It was going well, then my tweezers slipped and grazed the emitter - at first I thought maybe it was OK, closer inspection showed no such luck.
Sigh.
On the other hand, I put a driver and a emitter in a C8 host after that, and it was successful.
Never give up…
:C
That sucks.
You must have “grazed” the emitter pretty hard then because the HI leds still have a covering over the phosphor…
The tweezers must have penetrated that layer of gel or whatever it’s called.
It’s the dedomed LEDs that have fully exposed phosphor that comes off when you rub it.
I suppose at the end of the day its all part of the learning curve. Most of us have done a similar thing and learn to buy more than we need for mistakes. Well done on the second mod.
True, I always buy two of every LED I need from mtn electronics since they’re so cheap 
Its like having kids always have more then one in case one is a dud lol
I was playing with emitters once, and I poped the dome off, the light looked like a bright UV blue color!
LMAO
Yep, I still buy 2 of certain items. I’ve ruined just about everything you can think of. Learned to just slow down and take my time. Things still happen, though. Nothing like firing up the light for the first time and seeing a flash and finding out you burned everything up.
For me I have three terrific kids a loving wife. Bad luck for them as apparently I’m told that I’m the dud. 
Yeah, it was probably more like a “scrape” than a “graze” actually.
I feel like I was putting too much heat into the mclike with attached LED by holding the soldering iron on the wire/pad for too long, but it just refused to let the solder melt and accept the wire (I had tinned the wire and pad beforehand so I wasn’t expecting so much trouble). Shortly after the scrape, I touched to LED because why not at that point, and was surprised that the covering (silicone?) felt tacky.
Yup, that section where I scraped off the phosphor was surprisingly BLUE!
It not the end of the world I guess, I was planning another mtnelectrons order anyway so I’ll just add an LED to the cart.
rofl xD
nice one
I just burnt out one of my XP-G2s running it at 6A two minutes ago! Good thing I have a second! xD
I've bumped, grazed, dropped, even had one slide right off. They are normally pretty rugged.
If I use tweezers anywhere close I only use blunt end.
It all takes time like anything, and the best have mishaps.
One other thing, if you learned from it then it's never a failure...
Guys, I would like to ask how do you maintain your lenses clean and not scratching it after modding your light? I’ve been wanting to swap the emitters on my lights to my liking but cleaning the lens is one of my main concern and all those methods I tried has failed and leaving the lens with micro scratches :person_facepalming:. Any suggestion how to clean your lens without scratching it? TIA
Water + air dry = no scratch but lens gets water stains
soft cloth = scratchessssss
microfibers = scratches
lens paper = scratches
air spray = dust particles
edit: I mean reflector. My bad
MAD TM26 - do you mean lens or reflector? Lenses should not scratch so easily. For reflectors, I use the same techniques I use to clean a digital camera sensor:
Good post thanks for sharing.
Think of it as knowledge gained and thankfully shared.
I have an XPG3 incoming to do a swap on my 5 year old Quark AA.
I fully expect to mess something up, so I bought two emitters mounted on MCPCB
I completely empathise with you.
