Optics Evaluation

Posted on

The test fixture is our 24” LED Strip Kit custom assembled for Corbins Pet Store in Buffalo Grove Illinois.

The Heatsink is a 24” x 8.46” from HeatsinkUSA. The Cree LED strips are 6 XR-E Royal Blue/White and 4 XRE Royal Blue. The drivers are MeanWell 60-48D. The four Royal Blue strips are driven at full power (at 9 volts appx 580mA) in 2 parallel series of 12 LEDs. The other Royal Blue/White Strips are driven by a single MeanWell 60-48D adjusted to 750mA at 9Vdc

The drivers were adjusted and the input voltage was provided by a Radio Shack Enercell. Par was measured 24” above the fixture center mass and 24” centered but 12 “ to the side. The meter was an Quantum Flux Apogee meter MQ-200. Watts were measured with the common KillaWatt meter.

I was very surprised about the 70 degree optics performance. I did all measurements twice recording the highest average reading. In addition I did the 70 several times over and got the same reading. Shooting from the hip and using PDF performance data would give you a lower PAR. Personally I was surprised by the PAR improvement using these optic
