For manufacturing & 24/7 operations
The night shift never adjusts. Your lighting can help.
Earthlight models the Human ROI of circadian lighting for 24/7 operations — turning safer shifts, fewer errors, and steadier output into the language operations and finance already use.
01 — The problem
3 a.m. doesn't care about your output targets
The human body is built to wind down overnight, but the line runs anyway. Under flat, around-the-clock lighting, alertness dips on the night shift — and that dip shows up as incidents, errors, and inconsistent throughput. The cost lands in safety and quality reports, never on the lighting bill.
Workers
fight fatigue through the hardest hours.
Supervisors
manage the incidents and the gaps.
Operations
absorb the safety, scrap, and turnover cost.
02 — The Human ROI
Where the Human ROI shows up
Earthlight quantifies the levers that move an operations P&L — so the case for circadian light is made in safety, quality, and output.
Safety incidents
Better-supported nighttime alertness can reduce the lapses behind accidents — and the workers' comp that follows.
Error & scrap rates
Alert operators make fewer mistakes — fewer defects, less rework, less waste.
Overnight productivity
Lighting that supports alertness helps close the gap between day-shift and night-shift output.
Shift-worker retention
Conditions that respect human biology make the toughest shifts easier to staff and keep.
Absenteeism
Better-regulated sleep supports attendance on schedules that usually wreck it.
Consistency
Steadier alertness means steadier output — hour to hour and shift to shift.
03 — The science
Shift work fights the clock. Light can take its side.
Working against the body's natural night is one of the hardest things you can ask of people — and standard 24/7 lighting makes it harder. Well-designed, well-timed light can support alertness on the night shift instead of leaving workers to white-knuckle it.
Earthlight grounds its models in this circadian science and the standards advancing it, then translates it into the safety, quality, and output terms your operation runs on.
04 — How it works
From light to line item
01
Walk the floor
We map how light moves through production lines, control rooms, and warehouses across every shift.
02
Model the Human ROI
We translate circadian impact into the terms operations tracks: safety, quality, output, and retention.
03
Protect the spec
We give your facilities and EHS teams the numbers to defend circadian lighting before it's value-engineered out.
05 — Questions
Before you ask
Is Earthlight a lighting product?
No — Earthlight is decision-support software. We model and quantify the human ROI of circadian lighting so the right design survives budgeting. We work alongside your designers and vendors.
New facility or existing plant?
Both. Modeling the ROI before value engineering protects the design, and retrofits on 24/7 floors often pay back fastest.
Does the evidence actually hold up?
We build on established circadian science and recognized standards like the IES and UL. The Review walks you through the assumptions behind every number.
Who is this for?
Plant and operations leaders, EHS and facilities teams, and design teams across manufacturing, warehousing, and 24/7 operations.
