HIGH INTENSITY FLUORESCENT LIGHTING
UPGRADE CASE STUDY
 
 
SITUATION
IDEX’s Viking Pump division is a manufacturer of positive-
displacement pumps and flow-control systems for a variety
of fluid-handling applications. The existing lighting systems
within three of their facilities (office and R&D,
manufacturing and foundry) used a combination of
older T12 fluorescent, metal halide (MH), and high
pressure sodium based lamps. The systems ran virtually
full time. In the plant areas light levels ranged from
10-70 foot-candles.



PROJECT
Groom Energy engineers studied each facility and designed
a system using High Intensity Fluorescent (HIF) fixtures
which would produce the right light levels, with even
distribution and lower operating hours. With this energy
saving design completed, Groom Energy also secured a
financial rebate from Cedar Falls Utilities supporting
these projects.

Groom’s implementation replaced existing fixtures with
T8 and T5HO HIF fixtures throughout all three buildings.
High wattage 1000W MH fixtures were replaced with 10 lamp
T5HO HIF fixtures. Areas with low or intermittent occupancy
had motion sensors included. The plant’s redesign produced
an even 60 foot-candles throughout, while utilizing 25%
fewer fixtures. All three projects were implemented
quickly and with little disruption to Viking Pumps’
business operation.
