Most Par bulbs you find on Amazon, Ebay or even our competitors, simply use 6700K Whites and 460nm Blues.  We have taken our SB Reef  Lights proven spectrum and put it into a PAR 38 bulb.  Crisp 14K whites, 450nm Royal Blue for great coral pop an growth, 420nm for color development and additional pop, just enough 660nm red for growth with out encouraging algae, and one 520nm green for aesthetics. With 12 2w diodes it is powerful for such a small package.  

The included goose neck is heavy duty with a built in on off switch.  Short enough to not be in the way, yet long enough to get the light high enough for good spread and color blend.  

Bulb is rated for 50,000 to 100,000 hours of use, so 5+ years with normal use.  Large heat sink with convection fins for cooler operation and longer life.
