Fig. 5.11 Closeup of side-emitting rod showing light-scattering grooves
rods, which were commercially available from the fiber vendor, fit easily
within a conventional fluorescent troffer. Two of the side-emitting rods were
mounted in between T8 fluorescent tubes, as shown in Fig. 5.12. Significant
testing was performed to evaluate the uniformity of the light emission
pattern from the natural light emitted by the side-emitting rods, as compared
to the pattern of light emitted by the fluorescent tubes. This information was
used to adjust the design to minimize any variation in the light emitted by the
two sources [14].

photo-bio-reactor at Ohio University, rather than for conventional lighting.
As such, the system contained all of the prototype HSL system components
except for the luminaires. The installation of the first field system is shown in
Fig. 5.13.
