Abstract
Surgical procedures and patient examination activities have
been identified as critical universal health care components by
the 2015 world health assembly. These critical tasks often
require adequate lighting supply for successful execution.
However, surgical lightings are very expensive for rural health
care centres in middle and low-income countries. Besides, the
epileptic grid power supply has rendered the few available
ones underutilized. Technically, most of these lighting designs'
control mechanism tends to interfere with the concentration
of the surgeon or supporting staff during procedures. Hence,
an inexpensive surgical light with footswitch control and
battery bank is proposed. The prototype was implemented
using 85% locally sourced materials without compromising
standards in line with sustainable development goals. The
device passed the Chassis leakage test as well as mechanical
stability tests. On illumination tests, the device performed
seamless control tasks without distraction. It produces a
luminosity of 8500lx and correlated colour temperature of
6000k at an average cost of 109 USD.
