Output of LED and Traditional Lamps
Dr. A. J. Both of Rutgers University used our PS-100 spectroradiometer to examine the output of several LED lamps and traditional lamp and evaluated their usefulness for greenhouse and growth chamber applications. The lamps are compared to the solar spectrum and the Relative Quantum Efficiency (RQE) in the graph below.
| Common Spectral Lamps Efficiency | *Spectral Efficiency | LED Lamps | *Spectral Efficiency |
|---|---|---|---|
| HPS | 0.89 | Super Blue | 0.72 |
| MH | 0.78 | Super Red | 0.98 |
| INC | 0.49 | Cool White | 0.80 |
| FCW/FWW | 0.86/0.87 | Warm White | 0.82 |
| Sun | 0.64 | Plant Bar | 0.92 |
