Taming down the live-stream lighting.

Originally I tried using two of these lights vertically to give a good overall illumination, but the result was absolutely blindingly bright and the cameras swamped out a bit.
Then I went for a single horizontal one and it was still too bright.

Here's how I tamed it down with the added bonus of extending the life of the LEDs and driver greatly.

The original resistors were 3.6 ohm and 1.6 ohm in parallel giving a total parallel resistance of 1.11 ohm. So the removal of the 1.6 ohm resistor effectively tripled the resistor value (just the 3.6 ohm resistor) and reduced the power to about a third, which seems fine. The circuitry senses the voltage across the resistor/s to sense the current, so the higher the resistance the lower the current required to reach the sense voltage threshold.

Here's a link to the live stream channel. Best enjoyed with a drink and snack.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
