    The Latest in LED Aquarium Lighting

        The most efficient plant lighting on the planet engineered
    with the aquarist in mind, has just become more efficient.
    SolarOasis has released their latest model- the Aqua-Bar
     "ABP540" featuring 40% more light energy when compared to
     the original ABP5.  The ABP540 is able to meet the needs of
    planted freshwater or saltwater tanks requiring high levels of
    light.

            In order to understand the scope of this advancement, you
    need to understand that while the output has almost doubled,
    the electrical draw is still a mere 9 watts.  In terms of increasing
    efficiency,  the ABP540 is an incredible feat of engineering on
    the part of SolarOasis.  
       
          Designed for typical tank sizes, the Aqua-Bar ABP540 is
    small, lightweight, and scalable.  Each power supply will run up to
    four Aqua-Bars allowing you to easily add additional light or
    expand to a larger tank. Using a fraction of the electricity
    consumed by fluorescent grow lights, emitting virtually no heat,
    utilizing targeted wavelengths, with a lifetime that is 10-20 times
    longer than traditional bulbs- the transition to LED lighting in
    aquaria is inevitable. --AL

    The Year HPS Grow Lights Became Supplemental
           HPS grow lights have become a staple for year round production
    indoors.  High pressure sodium bulbs represented a breakthrough in their
    introduction to lighting that allowed us to come closer to our ideal
    wavelengths.  The price we payed was exorbitant electrical bills, safety
    issues, frequent bulb replacements, overheating, and white light pollution.  
    While we could be happy with the solution to any one of these problems,
    LEDs have solved them all.
           Does this mean that I think you should replace your 1000 watt HPS
    grow light with LEDs?  In the majority of applications including
                                                                                     greenhouses, plant
                                                                                     maintenance, or
                                                                                     extending photoperiod
                                                                                     in the winter months,
                                                                                     the answer is a
                                                                                     resounding yes!  There
                                                                                     are only a handful of
                                                                                     applications that would
                                                                                     not be suited for
                                                                                     lighting exclusively with
                                                                                     LEDs, and for these-
                                                                                     HPS grow lights are still
                                                                                     friends, but no longer
                                                                                     the leader of the pack-
                                                                                     more like sidekicks.  
    The most common example of an application that is best served using both
    LEDs and HPS is the basement garden.  While one can grow under LEDs
    only- plants will grow faster if HPS grow lights are turned on periodically to
    add radiant heat and stress directly to the plant canopy.  By using LEDs as
    the primary light source and moving HPS into the category of supplemental
    lighting we are able to increase the efficiency of any lighting system while
    obtaining the same end result.
            Using LEDs for the entire photoperiod and turning the HPS grow lights
    on for approximately 25% of that photoperiod will allow you to reduce the
    size of your HPS lighting system (if you are using 1,000 watt bulbs you
    could switch to 600 watt bulbs), run your HPS grow lights less,  extend the
    lifetime of your bulbs, and use over 60% less energy.   Sound appealing?  
    LEDs make everything better- even HPS. --AL
