Summary

This is a minimal LED lamp that gives you tons of light in a very small volume.
It uses $2 30W LED panels as found here: https://www.aliexpress.com/item/10pcs-50W-220V-Flood-Light-LED-PCB-SMD5730-Lamp-Plate-96mm-93mm-Integrated-IC-Driver-Directly/32515927294.html.

As I heat sink I used a 100mm aluminum profile.

Assembly is easy. Simply connect your power cable to the PCB, drill 4 holes in the heat sink and use 4 screws to fix the lamp to the profile.
