Hey.
I’ve got a point light with strength of 50000, and it’s producing less light than I’d have expected at that number.
The LEDs have strength of 1. The point light is 3cm in size at 256 bounces (~1.5"). Please keep in mind that the object is about 8" (15cm), and the unit scale is set to 0.001.
Making sure you have everything modeled at a realistic scale helps a bit (the same intensity value can potentially not illuminate well if that scale is way too high).
Don’t forget to adjust your camera clip start/clip end to minimize potential precision issues.
For reference - Blender in general considers one Blender Unit (the length of a grid square in perspective mode) as one meter.
