Malls
Malls and jewelry shops have thousands of halogen spot lights which generate an intense amount of heat, thereby increasing your cooling costs and also have a very short lifetime. Moreover their light keeps on falling which implies you don’t end up getting the constant illumination that is required by you.
A 6W LED focused light can easily replace a 50W halogen spot light and you get to have a very tight control over the kind of light colour you want. Also the beam angles can be easily changed by changing the lens.
