DV3092 Chambers
Conviron E15s in DV3092D had programmable fluorescent and incandescent until mid-September 2023. It was then retrofitted with Fluence VYPR PhysioSpec Broad R LED lights. Fluence RAY44 Pfr was added to E15.
Current LED light fixture configuration for 3092-01GC, -02GC, -03GC and -04GC:
Spectral Composition of current light fixtures in 3092-01GC and 03GC:
Figure 1. 3092-01GC & 03GC light composition (%) of different light set points. The bar graph above uses chosen white light and far red light set points that result in a unique light composition for experimentation. Light composition percentages were not shown for UV and B due to its very small values. The values at the y-axis labels are in units of PPFD (µmol/m2/s).

PFD = Photo flux density, PPFD = Photosynthetic photon flux density, UV = Ultra violet, B = Blue, G = Green, R = Red, FR = Far red. Look at the actual PFD value table to view small PFD values (UV), and wavelength range (nm).
