What did you mod today?

I had already posted these on BLF back in 2015, but that was before this thread was started and I still use both of these lights regularly.

3x XP-L SpiderFire C2

Coast HP1 3x Nichia 219C - Original mod had an older type of Samsung LED and I upgraded it some time after this thread.

I’m currently working on a few lights, including swapping out the XP-L HI in my Sunwayman V10R for a 219B sw45k, and swapping out the 4x XP-L HI in my Emisar D4 for 4x LH351D 5000k.
