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:
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
FL tubes do not like switching, their lifetime declines sharply with frequent switching
e.g., automatic staircase lights, elevator lights
where the costs of exchange are substantial
e.g., high ceilings, factory lighting, outdoor advertising light boxes / billboards.
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
when the tube is operated
in A/C cooled areas
