Each 30cm (18") ComboRay unit is basically composed of the following components: (a) 6x relaceable LED on 2.5cm x 2.5cm MCPCB, (b) one circuit board (PCB) with power and signal layout, (c) aluminum heat sink with pre-drilled screw holes, (d) tempered glass, and (e) 2x aluminum side covers. The ComboRay unit can be mass-produced efficiently due to its simple design. Users can easily replace of the LED by loosing and re-tightening the screws. A ComboRay unit can be used as the main light source for tanks with shorter width (<30cm) and depth (<45cm). For wider tanks, the light spread can be extended by combining multiple units. With regard to big tanks which are longer and higher, ComboRay can serve as functional light source, such as supplementary or actinic light to fulfill the demands of better hue and full spectrum.
There are currently seven types of LEDs of various colors, which are 400nm Near-UV, 420nm Violet, 450nm Royal blue, 470nm Blue, 500nm Cyan, Cool White, and Neutral White. One should have noticed that 420nm Violet and 500nm Cyan are the two colors which are not included in the Blaze series products. With the addition of Violet and Cyan LEDs, a full spectrum light source can then be achieved. Trust me! You will never be disappointed with this new product.
