Congrats!
The manual
https://www.hdssystems.com/Products/Legacy/EdcBasic/EdcBasicUsersGuide.pdf
Says:
"Your light is configured at the factory with the following settings:
- Maximum setting: 42 lumens
- Primary setting: 10 lumens (turn-on setting )
- Secondary setting: 2 lumens
- Minimum setting: 0.3 lumens"
—-
The lowest level available if you access brightness menu is 0.08 lumens
I recommend Disabling option 4, which is required before you can change brightness level of preset D from 0.33 to 0.08
Here is the manual for the programmable interface:

It says:
"Note: you may notice a slight flicker on the very low brightness levels. This is normal."
And
"You enter the Options Menu by 10-clicking [250 for the Basic] the button while your light is turned off. Your light toggles on and off while you are clicking but this is normal. If you don't want to count, just keep clicking until your light stays on."
To do the 250 click i like to place the light, bezel down, on a table, then start mashing the button
Here are the brightness levels available:
