When LEDs are utilized in wall loads with borosilicate glass, the optics of the fixture do not work the same way. For the LEDs to be efficient they have to strike the glass at various angels. In a lot of circumstances this impedes the performance of the LEDs and the overall light output. Efficacy can be reduced by modifying the positioning of the LEDs to gain back quality optics.
The primary reason for the photometric modification is the distinction in the source of light. Metal halide, high pressure sodium, and compact fluorescent lamps blast light in all directions. LEDs are a point source. This resembles the why a halogen filament can be directed in a PAR38, and fluorescent coils in the very same lamp shell blow light everywhere.
