That setup was built using very cheap Samsung strips that were removed from damaged light fixtures (Ebay) and very cheap $20 power supplies from Amazon. Total cost was around $200-250 or so (guessing). I was running those around 1000 watts and they have a capacity of around 1440 watts.

Sorry to derail, just showing what is possible if you fall in love with building your own.

Yours has to the DIY set-up I admire the most. All about the full illumination.

I bought that heatsink for my qb288s cause hlg was out of the slateheatsinks. Then I got a slate heatsink, so used it for 2 f series double strips.

Different profile. The one I have is only 15mm wide - its their smallest one, but it fits the single row F series perfectly.
