We are pleased to announce that we have just introduced our new PAR38 CR19 Refugium Light for lighting refugiums and mangroves for only $79.
The light operates at a true 19W of measured power.
This light is ideally suited for growing aquatic plants including Chaeto and Caulerpa macroalgaes as is commonly used in reef tank refugiums. It is also well suited for illuminating mangroves and other above water plants. In addition, the lighting spectrum is suitable for invertebrates commonly found in these systems.
Plant photosynthesis utilizes light primarily in the red and blue spectrum. These lights utilize 460nm Blue LEDs to boost the blue spectrum and warm 4500K and daylight 6500K LEDs which have a high red output, but because they are white LEDs, they also provide broad light spectrum coverage. This broad lighting spectrum provides a more natural warm white look unlike lights which only use red LEDs or red and blue LEDs. Those lights are best suited for algae scrubber applications. For that application we offer 35W grow lights.
The lights have 90 degree optics over the LEDs. In practice, the 90 degree optical lenses provide an effective usable light spread of approximately 60 degrees. The chart below shows the approximate light spread and light intensities that can be expected at various illumination distances. This chart assumes a 6″ distance from the light to the water surface. The PAR measurements are taken directly under the light. The light intensity will decrease as you move towards the edges of the light cone.
The picture below shows two CR19 Refugium lights over a 40g breeder tank setup as a refugium and being used to grow Chaeto macroalgae and caulerpa. The tank is 36″L x 18″W x 16″H. The water depth to the sand bed is 12″. T he lights are approximately 8″ above the water. There are also some misc corals such as Xenia in this tank which are also doing well under the lighting spectrum.
Price is only $79 with free shipping. We also have PAR light mounting accessories available. Go to website
