sst-50 dimming, xml2 question

LED Flashlights – General Info
1

Hi, I was modding a tr-st50 driver and I had some issue with the wire, it shorted in negative resulting in direct drive (seems the negative handle the current)……

So, the sst-50 was submitted over 13,5A and got blue tint, I didnt know whats going and I try 8x turn on and turn off, after this I measured the tailcap current (over 7,5A).

I solve this issue and complete the resistor mod giving 3,5A on tailcap, the light was OK but now its so dimm compare in past….

That overload damaged the led or 6A+ is too high for sst-50?

Only for effect for compare, I tested the ceiling bounce on naked eyes with tr-3t6 and both almost the same output, but now its only a half of that :_(

I thinking to swap with xml2, but fasttech only have aluminium star, the question is xml can handle 6,5A with al star without problems?

Thanks :slight_smile:

Probably not, the XM-L2 will not be able to handle 6.5A without a copper star.

You might want to get some Noctigon copper stars, those seem to be the best.

Where I find this led with good price?

I was looking for sst-50, but te price is too high, over 4x than price of xml :~

There are pre mounted LED’s at intl-outdoor.com

You’ll be able to find them there.

Thanks Ryan, I ordered one yesterday in this store :slight_smile:

But, I still want to know if 6~6,5A is too much for sst-50, I REALLY like the beam pattern floody/thrower, but it’s ruined in 3 days of use :frowning: :_( :weary:
