Justin sent me his light meter which has identical readings to mine. Same brand. He calibrated his with selfbuilt readings and got a correction factor of 1.13. His read low just like mine.
Anyhow using the same correction factor I measured 5000lux at 5 meter. 5650 Lux with 1.13 correction factor. This gives:
At turn on:
~140K lux at 1 meter. ~750 meters of throw.
At 1 minute:
~137K Lux at 1 meter. ~740 meters of throw.
