Recently at our JHB club reef meeting we managed to get 3 LED units, available to all reefers, together in one spot.
We also managed to get a PAR meter.
We did this experiment just as a reference point as to what each unit is capable of.
We did not measure PUR which is what the Guru's recommend we measure LED lighting in.
The Experiment was conducted in one tank 550mm deep with no overflow or sump. We placed the PAR meter sensor on the substrate and turned off the flow pumps.
All three units where placed at the same hight above the water.
The LED Units tested.
2 x Vertex Lumilux power (60W/unit)
1 x AQUAIllumination SOL (72w)
1 x DIY Cree LED's (74W)
The Results.

The AI SOL - 221

The DIY Cree - 388

Please note the tank has been running succesfully on the vertex lights for 4 months.
Also as a side note, the vertex units are non lensed, the AI Sol uses a mix of 40/70 degree optic lenses and the DIY unit is using 60 degree optic lenses.
