Scope: Replace existing high pressure sodium flood light with LED
A ballast went out in an exterior flood light. The cost of the ballast is $15 cheaper than upgrading to a more long lasting and energy efficient fixture. The ease of replacement ends up saving labor costs, off-setting this additional expense. The LED provides a crisp clean light that feels more secure.
Results:
From 295/fixture to 50w/fixture
From 14,000 hour lamps to 50,000 hour LEDs
Expected ROI 0.5 years
