The 400watt 48" version is $2,800, or about $500 more than the 250 watt 48".
<p style="text-align:center;"><div style="text-align: center;">[B]<span style="font-family: Tahoma;">PFO Lighting is proud to introduce the
</span>[/B][B]<span style="font-family: Tahoma;">NEW</span>[/B][B]<span style="font-family: Tahoma;"> H4 Series Solaris LED Illumination System</span>[/B][B]<span style="font-family: Tahoma;"></span>[/B]</div>
<span style="font-family: Tahoma;">The Solaris is the first LED System designed to replace Metal Halide and Fluorescent lighting for the Aquarium Reef Tanks. It has been in development for over two years. It will change the way Aquarists light their tanks from now and into the future.</span>
<span style="font-family: Tahoma;">The H4 series (400W 20k equivalent) is the exact same size with the same light spread as the original G series (250W 20k equivalent), but with 30% more light output and 30% more energy usage. </span>
<span style="font-family: Tahoma;">The new H4 series produces </span><span style="font-family: Tahoma;">PAR</span><span style="font-family: Tahoma;"> light output levels equal to a 400W MH 20k. It uses 40% less energy than the 400W MH 20k fixtures it replaces. The life of the LEDs is approximately 50,000 hours, so it almost eliminates metal halide and fluorescent bulb replacements. All heat is radiated up and away from the tank; therefore, it does not heat the water like Metal Halides or Fluorescents. This eliminates the need for Chillers. The room air conditioner needs to work ½ as much since the light fixture produces only ½ the heat of Metal Halides which saves even more energy over traditional lighting methods. </span>
<span style="font-family: Tahoma;">As with the G series, there is a built in microprocessor that controls the H4 series Solaris. This not only eliminates timers, but it allows the unit to dim the actinic blue LEDs, white LEDs, Lunar actinic blue LEDs and Lunar White LEDs independently from 0-100%. This dimming capability opens many opportunities. The light can be adjusted from 6.5K to 22K, or anywhere in between, to set the ideal color temperature. </span><span style="font-family: Tahoma;">Sunrise</span><span style="font-family: Tahoma;">, Daylight, Cloud Cover, Sunset, and the lunar cycle, can all be set independently.</span>
<span style="font-family: Tahoma;">Coral Growth has been outstanding with the new lights. There is excellent water penetration of the light. </span>
