IR LED illumination power

I want to use the NOIR camera module for night vision, but would rather power some IR LEDs separately than draw power directly from the camera module. I have the IR LEDS, the ones that would typically screw directly to either side of the camera module. However, nowhere can I find the polarity of the power connection to these units.
Just two connections, for mounting and power, one near the LDR for ambient light sensing, the other near the light level trigger adjustment.
Anyone any idea which is +3.3v and 0v.

Ah, finally found the answer myself.
For anyone else interested, I've attached a photo, +3.3v at the LDR end, 0v at the adjustment end.

What and how do I use to power these, because I want to do the same thing. Would you post a pic with the finished IR powered up please.

I have mine powered directly from the GPIO pins on the Pi, it is easily bright enough to illuminate the inside of my shed and capture images with a NOIR camera.

I have tried that. I am using the Kuman for Raspberry PI camera Module 5MP 1080p OV5647 sensor HD video Webcam Supports Night Vision For Raspberry Pi 3 model B B+ A+ RPi 2 1 Camera SC15. The camera works fine but the IR freezes up the camera module. So I took the IR off of the sides and ran them from the pins. I get the same problem. So I am looking for night vision that would work independent from the pi.

Hi,

I use a Bright Pi, its not going to illuminate a room but OK for closer subjects, powered from the GPIO pins and controlled by I2C..

We use to to spy on the Hamster in his wheel at night :)
