Yes but they are supposed to be used as a replacement for MH with existing reflectors. The optics is at 77 Degs. Supposed to be at 6" above tank. Also keep in mind that most LED lighting in the market do not have proper design for heat dissipation (i.e. heat sink), and lead to pre mature failures. And no actinics for street light applications.
