Hybrid Lights (T5+LED): How much PAR from the LEDs?

Kengar · 08/21/2019, 11:57 AM

I have ATI PowerModules, 8x39 Watt T5s with 2 LED modules per unit.

Does anyone know how much PAR might be attributable to the LEDs if the LEDs are running 100%, as compared to how much PAR is attributable to the T5s?

I'm looking to buy a PAR meter and this bears on which unit to get. If T5s are the dominant driver, then Apogee 210 may suffice. Otherwise, if LEDs put out meaningful amounts of PAR -- i.e., if they contribute more meaningfully than just aesthetics -- then it may be worth getting the 510.

Thanks.
