DE FIXTURES COMPARISON TESTING

Phantom DE Systems vs Other DE Market Brands

Independent Testing Laboratories, Inc. (ITL Boulder), the most experienced independent photometric testing lab in North America, was recently contracted by Hydrofarm to conduct independent testing of eight commercially available competitive double-ended horticultural lighting systems. Based on the test results generated by ITL, Hydrofarm’s Phantom Commercial Open Lighting System and the Phantom Commercial Enclosed Lighting System were ranked first and second place, respectively, in all of five testing categories (relative efficiency, total µmol/s output, µmol/s per watt, absolute luminous flux and lumens/watt).

 

DE Fixtures Comparison Testing

The Phantom DE Systems consistently outperform the competition on every level!

These test results show that the Phantom systems have now been scientifically proven to deliver higher PAR than the other popular systems tested. The Phantoms have also been confirmed to be more efficient, require fewer fixtures to deliver desired light levels, and as a result are more cost-efficient than the other six fixtures in the testing group.

All testing was conducted on commercially available luminaires ("commercially available" is used here to indicate units chosen at random from retailers' stock to assure that they represented off-the-shelf quality and were not modified to enhance performance for testing).

Total Luminaire Efficiency

Chart Relative Efficiency

Shows how efficient a luminaire is by comparing the total rated output of a bare lamp versus what percentage actually reaches the plant canopy when the lamp is installed in a luminaire. Luminaire efficiency takes into account the effect of the luminaire on the performance of the lamp. This testing was performed using a Type C goniophotometer in conjunction with an integrating sphere and calibrated spectroradiometer, which provided very accurate calculation of photon flux, spectral power distribution, and umol/s output.
 

Total µmol/s Output

Chart Total umol Output

Shows the total amount of plant usable light or PAR being emitted by the fixture.
 

µmol/s Output per watt

Chart umols/watt

Shows how much plant usable light or PAR is being delivered in relation to the wattage the fixture consumes (how effectively the fixture converts electricity into plant usable light or PAR).

Absolute Photometric Testing

Absolute photometry reports the actual output of the luminaire, without any scaling. This type of measurement requires careful calibration of the goniophotometer’s photo detector/amplifier system using a lumen or candela standard lamp. An absolute photometric report binds the report to the specific lamp(s) of given characteristics used and the specific ballast(s) used. This limits the value of this reporting technique, however it is very useful in troubleshooting a problem project.

Relative Photometric Testing

Relative photometry is based on scaling the light output of a lamp or set of lamps to match that of the manufacturer’s rated lumens. To obtain this scaling or multiplying factor, a determination of the bare lamp(s) output must be done. This bare lamp exploration can be accomplished using a goniophotometer to determine the light output of a given lamp/ballast combination.
