the plane x again referring to fig3 it will be seen that the bulb 40 of the left hand fixture 35 casts light generally toward the right and along the target plane tp that the bulb 40 of the right hand fixture 35 casts light generally toward the left and that the bulb 40 of the center fixture 56 casts light in both directions as a result the center portions of each tier of shelves 30 are illuminated with light which has generally the same intensity as the light at the ends of the shelves fig1 is a graph showing the change in light level as a function of horizontal distance along the target plane tp from the light source and demonstrates the improvement obtained by the present lens reflector system where light level is indicated by a dashed line 95 as compared to a bare bulb of the same wattage and of the same physical size and shape the light level of the bare bulb being indicated by the solid line 96 from fig1 it is apparent that the light level of the present system is less adjacent the bulb but is greater remote from the bulb so as to provide a more uniform gradient the more uniform gradient not only casts more light on products remote from the source i e at the center of each tier of shelves 30 but also reduces glare at the ends.
