All done,  was rather tricky.  The sensor just needs milling into the heatsink close to the aluminium base as possible

The second photo I took with the flash on as it doesnt come out as it looks.  The edges are clean and I'm pleased.  This is the 300w (575 replacement)

After 40 mins it settled on 54.6 on full brightness.  The sensor is mounted right on the led aluminium base. The led die (part where electrons cross) is approx 70 degrees,  way below the 150 degree maximum.  The 100,000 hour lifetime spec is typically when the aluminium base is kept below 85 so it should last forever
