glad your diode is ok! it's not a good idea to direct drive them with just a battery tho...

Default Re: 9mm 445nm Troubles

TO clarify a few things so that no one gets confused.

For the future if you are confused about anything just drop me a line.

It was not me who said not to use Arctic Silver. That must of been another member.
You can use either arctic silver adhesive or alumina adhesive. It doesn't matter. I just prefer alumina more as its much cleaner.

Though i have heard arctic silver adhesive causing issues with shorts and stuff like that before several times from people but it has never happened to me or i cant say it has happening to anyone with an X-Brand of drivers. Personally i dont think that the Arctic silver adhesive would have been the issue in those peoples cases but hey i dont know.

Also the SXB is CONTINUOUS GND.! So the BOTTOM EXPOSED PAD is GND. NOT POSITIVE. "Dont want anyone to get confused" SO that is not an issue.

Damage must have happend to the driver if it was working fine for so long then started to have issues. The driver might be fine still and the issue might be too much currant draw and over time the switch built up resistance or whatever else like a spring or something.
Though some times things have a shorter life then expected but its very rare if everything was done correctly. But it can happen. Thats Life for you.LOL

This is very common in high current application and is HIGHLY UNFORGIVEN if even a small error is over looked.

The Flicker is a sign its overheating or sagging/tring to protect itself. (Could very well be over time the switch in the host has build up resistance or can not take the currant anymore.)

You guys got to understand the SXB is not some dinky Driver.

Running a 9mm diode at 2.4A and taking the cell down to 3.6V will make it draw probably around 5A+. That is alot in BOOST MODE.

Resistance or any restriction can make the driver run much harder and if not caught well we know what can happen.

As i know the Saik host used the smaller 2A version switch and from time to time i know those kind of switch's go bad or build up more Resistance which can make the driver work not like it should and cause it to die. Even a spring can cause a build to not be able to run full power and cause issues.

You are dealing with a very powerful driver here that just like any high power electronic is not forgiven.

These high currant driver that we are creating on the forum today are far past any basic setup and more care needs to be taken in beefing up connections and so on.

I can almost bet that 2.6W was LOW and the restriction/problem was from the beginning.

How do i know that this could be a problem because i tested it out and switches and spring/Pills and so on need to be strong enough to allow the currant to flow. Remember the Grooves way back that the switch was failing with only 1A.? Well in some cases that also made the driver flicker. Remember. That is only 1A. Imagine 5X+ that. If they are not failing then they will restrict currant causing them to heat up and also make the driver work that much harder and over time will fail.

The Saik host can handle a X-Boost Just fine since currant is much lower on these drivers. With an SXB at 2.3A your 32650 will be relay pumping. SO i like to beef things up on connections Just to make currant flow easier. It doesn't hurt.

Sometimes overtime things go bad but it is very rare in these electronics if everything was done correctly from the beginning but it happens. Ive had plenty of un explained stuff happen to me before.

But iam glad the protection in the driver stopped it from damaging your diode.

KRNAZNBOY: I do replace drivers. Regardless of the issue, Unless i see someone taking advance of my kindness. If someone is honest and tells me what happened i dont mind sending a replacement.

After all it is very rare i see fails even if it user error SO iam OK with given replacements to good customers like yourself.

Drop me a line.

Default Re: 9mm 445nm Troubles

I have done some more testing and the diode is in no way damaged. Originally outputted 2.6 watts at 2.4 amps, now its outputting 610mw at 570ma.

Looks about right!

I took apart the saik, pried the old driver off, and prepared the host for the reinstallment of my 9mm diode!

I took the old driver and re-soldered all new, shiny-joined leads, and i plan to send the driver to lazeerer to see what's wrong.

Thanks for all your help guys!
Thanks lazeerer! You are the best!

-Matt

Yup Angelos is the man. I had a very slight problem with a x switch driver and it was taken care of a quick as possible. Awesome guy.
