This will be a pendant, hanging about 36 inches from the substrate, 12 inches above the top of the tank. The 4" diameter, 30 watt pendant I tried did not produce enough PAR at the 36 inch distance, so I dropped the project and sold the parts on the For Sale forum.
The SMD tape will provide about 300 LEDs, for about $15! These are 30 lumen LEDs, not the tiny output ones the original LED tape used. I chose them because I want to try them, they are cheap - very cheap - and my PAR calculation program says they will work. Also, they don't need a LED driver - each LED has a current limiting resistor build in.
Also, I have noted that Finnex LED lights use SMD LEDs, so it is certainly possible to generate high PAR with them.
