[Help] Reflowing XHP70

Flashlight Modding and DIY Parts

Wondering if someone could help real quick. I’m changing out a cool white XHP70 to a NW XHP70, and the orientation indicator on the back is different on the two. One has the little sideways “T” where the straight line points to positive. The new emitter has an arrow on one side. Pretty sure the pointy end of the arrow points to positive, but wanted to run it by you guys to make sure. Here are the pictures. Thanks for any feedback

Robert, I found this image on page 28 of this PDF on CREE’s site.

Hope this helps!

Thank you, that helps a lot. Exactly opposite of what I was thinking!

Glad it helped!

I guess it would be too much to ask for a + and - on the PCB? :stuck_out_tongue:

The Acebeam EC50 GEN II had a very cool white emitter. Changed it out with a XHP70 N4 3C 5000k. Much better tint. Thanks again!

3C my favourite cree tint. I have a 3c xhp70 and the tint is perfect for me
