The FGI Lightbrick 500, the ultimate HPS replacement LED

Using our patented light engine, the Lightbrick is specifically targeted as a 1:1 replacement for double ended HPS in greenhouse and indoor applications. An IP67 rating means this lamp is suitable for wet locations. 

We've added our special optical lens to provide for very even distribution of photosynthetic light allowing growers to target the PAR intensity they desire. 

Mounted at 36" above mature canopy the Lightbrick will achieve up to 1356 umols/s/m2 PPFD.
