Measurements of the lamp using the optical power meter along with the corresponding calculated 8‐h doses.

Sensor configuration	Height (m)	Offset
		0 m	0.5 m	1.0 m
Measured Irradiance (μW cm−2)
Horizontal irradiance	1.8	3.100	3.100	0.300
	1.3	1.200	1.700	1.100
Direct irradiance (meter directed at fixture)	1.8	3.100	3.700	0.550
	1.3	1.200	1.800	1.400
Vertical irradiance	1.8	0.025	1.300	0.300
	1.3	0.018	0.260	0.530
Calculated 8‐h dose (mJ cm−2)
Horizontal irradiance	1.8	89.280	89.280	8.640
	1.3	34.560	48.960	31.680
Direct irradiance (meter directed at fixture)	1.8	89.280	106.560	15.840
	1.3	34.560	51.840	40.320
Vertical irradiance	1.8	0.720	37.440	8.640
	1.3	0.518	7.488	15.264

The maximum calculated 8‐h dose was chosen as the maximum directly measured dose (106.56 mJ cm⁻² for this study, bolded text).
