My question stems from this video: https://www.youtube.com/watch?v=iVrJUbeuG44
He states that he uses 24 drivers for his 8 5w blue diodes in the array. Does this mean that he is using 3 drivers for each diode? How does that work?
Also it looks like he is using a simple convex lens to focus all the diodes or am I seeing it wrong?
Thanks.
