Source: https://www.cloudynights.com/gallery/album/19972-diy-flat-panel/ Aliexpress is selling some round LED panels that are quite powerful with a diameter of 10cm or 15cm and remote control (https://www.aliexpress.com/item/4001197089000.html). I also found some White PTFE Film/Sheet, and some acrylic discs 160mm diameter. All that to diffuse the light. I have only received the LED panel so far, which can be powered on 5-24V. So I have soldered a 12V DC 5.5 2.1 female adapter.

I used: - A 12V DC 160mm LED Panel rom AliExpress with a remote control - 2x 2mm acrylic discs to diffuse light - Some parts I've 3D-printed in ASA black and white (ASA because the LED panel generates a lot of heat) - Insets, screws, etc The first disc is ~ 5 mm above the LED panel and the second one is about 3 cm above This diffuses light better than having 2 discs close together to the LED panel. I did some tests in the center and at the extreme borders (at 3 positions) with a Light Meter. I get: - At 25% power: 24K lux on the extreme border, 30K lux in the middle - At 50% power: 40K lux on the extreme border, 60K lux in the middle - At 100% power: 94K lux on the extreme border, 130K lux in the middle The light becomes quite flat as soon as we are 1 cm from the borders. It is able to accommodate a diameter of maximum 125mm.
