Pi NOIR Cam with IR LED

I use an OEM NOIR Pi Cam that does not have power traces on the PCB mounting holes, so I designed a lightweight camera & IR led mount.

My mount is designed to directly fit the gooseneck jointed arm setup: https://www.thingiverse.com/thing:4227360 from TR-909

Hardware:

4x (M1.5x4) self tapping screws - Camera PCB to Cam_Holder

4x (M1.7x8) self tapping screws - Holder back to holder front

2x (M3x12mm) Nut & Bolt - Holder back to gooseneck attachment

1x (M3x20mm) Nut & Bolt - Gooseneck attachment to gooseneck

electrical connections are made via tiny ring terminals, I used these ones:

The IR LEDs I used are:

Akozon Infrared LED Light 1 Pair LED Fill Lights 3W Illuminator For Raspberry Pi 3/2/B+ Infrared 850IR Night Vision Camera Module

They are not anywhere near 3W, they all seem to say that.
I power them via a 3.3v:
