Our spectroradiometers measure radiation with 1/2 nanometer bandwidth resolution.
Irradiance
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.
In the graph at the right, these lamps are compared to the solar spectrum and the Relative Quantum Efficiency (RQE).
| Common Spectral Lamps Efficiency | Spectral Efficiency ∗ | LED Lamps | |
| 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 |
