Economy and Return of Investment
LED tubes are expensive, more
than 10 times the price of FL tubes.
Aside of their environmental
advantages, LED tubes return profit
in the following cases:
Long
operation hours, where the power savings
justify the higher price
e.g., Walmart
is replacing all FL tubes in cooled areas by LED
tubes, ROI in half a year
Frequent
light switching
FL tubes do not
like switching, their lifetime declines sharply
with frequent switching
e.g., automatic staircase lights, elevator lights
Difficult
locations
where the costs
of exchange are substantial
e.g., high ceilings, factory lighting, outdoor advertising light boxes
/
billboards.
Sample ROI Calculation
Notes:
The LED tube would
save 1.3
tons of CO2
as compared to the
FL tube.
This sample
calculation does not
take into account:
-
The light quality:
FL tubes with comparable
quality light
are about 3 times as
expensive
-
Energy savings
when the tube is operated
in A/C cooled areas
-
Costs of financing
