Hi Julienvoirin,
thanks for your suggesting but these leds are colored cristals clear and aren't eye killer (the light of the picture doesn't return real color and they are green ).
Years ago my ex company worked for GEM and these leds are from GEM PROMEGA so i saved a little batch of them.
I already used in other stuff and never had the problem given from cristal clear leds.
Only the BEAT led is blue cristal clear and if it will give me problem i will change it.
When i will finish the sequencer ( hope to finish soon :whistle: ) i will post some image or video to show it.
Regards
Antix
