I don't have any shareable pics of the final unit. There are some pics of a previous build of a 5000 lumen prototype here: #291
The beam is extraordinarily even and clean. Absolutely no hot spot. The later modules use a regulated current driver instead of the direct drive. Each LED has its own independent driver/thermal manager. They are all networked together.
There's talk of doing 500,000 lumens... I saw some specs for a 60 inch carbon arc searchlight that says it does 300,000 lumens (seems a bit low) with 15KW.
