Want to prolong the life of your light bulbs without having to cut back on the hours of light your aquarium receives each day? There are a couple of different options that could help you along. For one, it’s best to drive the lamps at their proper wattage/voltage/etc. Lamps that are overdriven use more energy than they are optimally rated for and will not last as long. Additionally, lamps that are placed in an extremely hot environment and do not have proper ventilation will have a much shorter lifespan.
