Descrição
These easy-to-make LED ring lights are intended to be used with the Lumetra Modular Photography Stand System. They can also be mounted on a regular camera tripod using the corresponding tripod-to-ball-socket adapter, also available at the link above.
Most dedicated photography LED rings commonly sold on AliExpress and Amazon cost 50+ EUR, are dimmer than advertised, and too stiff to position at the angles you need.
Making Lumetra LED rings is 5 - 10 times cheaper, and most importantly, you get their full rated light output instead of an underdriven fraction of it. They're versatile and easy to use - perfect for quick product shots, video, or a handy addition to your workbench.
Printing
Print the enclosure in black PETG or ABS, and the diffuser in transparent PETG/ABS. Before printing the diffuser, heat the nozzle and wipe it clean with a soft cloth, then purge a small amount of transparent filament to clear out any residue from the previous filament. This prevents spots on the diffuser - not a functional issue, but avoidable with this step.
Several print profiles are available for different LED ring sizes and power ratings:
- 190 mm / 24 W
- 230 mm / 36 W
- 248 mm / 48 W (with remote)
More LED ring sizes can be added upon request. Here are some AliExpress links to purchase the LED rings. If the links are no longer active, search for "ceiling LED ring" followed by the desired wattage or diameter.
24W and 36W, no remote:

Once your LED ring arrives, make sure its dimensions match those shown in the print profile picture, most importantly the distance between the mounting points (±2 mm) and the outer ring diameter (+5/-20 mm). If they don't, feel free to message me - I can create a custom enclosure for you.
