Spot lights have been around for a long time and are now replaced by energy efficient LED track lights. Gone are the days when you feel hot and bothered by the relentless heat emitted by halogen spot lights which were also expensive to boot.
There is an upgraded LED technology popularly known as COB or chips on board. COB LED technology uses a process by which multiple LED chips are packaged into a single LED module, thus making it less glaring to look at and the light emitted is more evenly distributed over a wider area.
