Hi all,
intl-outdoor has XHP50 6V~12V…What does User Configurable mean? I want the 6V option to drive off 2 x 26650’s via DD. I would get it already mounted on the copper star.
(I am thinking its like the MTG2 6V LED which runs perfect off 8.4V input)
Do you see how on the bottom of the LED, the anode and cathode pads are split in the middle to be 2 pads [each]? The same LED can be used at either 6 or 12v by the way you wire it up.
Yup…I see the bottom and the T shape cut outs on each side, but how would I that come into effect for me If I am buying already mounted on copper board. So, I would never see the bottom of LED
Do we know EXACTLY that MCPCB’s they come on? There’s a few options, either the board is specific to the voltage you want to run (i.e. you specify when you order and you cant change it) or it could be like a sinkpad where the MCPCB is the same between 6v and 12v and you can add / remove solder jumpers on the face of the MCPCB to change the voltage it runs at.
Since it’s at Intl-Outdoor, and the only option there is Noctigon, I expect an XHP50 will be in 6v configuration an XM-L mcpcb. If you want 12v, you would need to buy the bare LED and reflow it yourself onto an XHP50 sinkpad.
yeah, I think I would have to confirm somehow that it comes on 6V board. Especially hard since they don’t mention it or show pictures of the copper board they would provide.
Where Do they sell sinkpads for XHP50 or XHP70 in the USA?
If you just need one I can hook you up (no charge). Drop me an email (link below in sig)
If needed I can also reflow an emitter on and configure it how you need (of course you’ll have to provide the emitter) but I can reflow it for you also at no charge. If you need just the sinkpad MCPCB I’ll drop it in an envelope and stick it in the outgoing pile today, if you need an LED solderd on we can work that out too.
XHP50 will work on any XM mcpcb but in 6V mode only. To use it with 12V the +/- pads need to be split and have an extra trace to run the two halves in series. Somewhat similar to mce but only 2 instead of 4 address able circuits.
Max current for 6V is 3A same as XML but C/W is less than half (2.5 vs 1.2) so I’m wondering just how hard we can drive them or how susceptible they are to over current.
Wow, I would not have expected that much power through them. Still, the relatively hgh Vf of the 50 will limit 2-cell current. Can wait to see how a J2 3D looks.
