Not your average spec sheet

We are at the frontier of circadian lighting development, and as such, metrics for circadian lighting are yet to be widely adopted in the lighting industry. For that reason, Loop's specs sheet includes metrics you're unlikely to find used by other lighting manufacturers.

Instead, we draw on circadian lighting-specific metrics and recommendations developed through expert scientific consensus (Brown. et al, 2022) and the WELL Building Standard.

Light Output

Peak day brightness	1788 cd/m2
M/P ratio	3.84
Circadian light: Day to night ratio	30 to 1

	M-EDI	EML	CS
Day	243	267	0.374
Night	8	8.7	0.022
Night (dimmed)	>1*	>1*

Results measured independently by UL Testing at the eye with no other ambient light. Read the full report here.

*1 Not independently tested

Exceeds Brown et.al 2019's recommendation of ≥250 M-EDI during the day and ≤10 M-EDI in the evening in a real-world setting.

Meets the WELL Building V3 recommendation of ≥275 EML in a real-world setting.
