Are you confused and tired of all of the hype and claims made by lighting manufacturers? We were, so we tested our most popular light fixtures and provided real data to help you determine the best value in lighting for your aquarium.
All tests were performed on 48" fixtures.
Bulbs were allowed to reach full operating temperature.
Lux measurements performed with Milwaukee Digital Lux Meter in a room with no windows and minimal room lighting.
All electrical costs based on 11 cents per kilowatt hour with all lights on for 14 hours per day.
Fixture prices current as of January 2009.
Bulb replacement costs based on replacing bulbs every 6 months at our January 2009 pricing.
The test meter was placed 12" directly below the centre of the fixture.
