Abstract
Lighting plays a big part in making a first impression for your
establishment and ensuring a comfortable environment. The right
light levels will make people feel welcomed and at home. A
compact fluorescent lamp (CFL) is a type of fluorescent lamp.
Many CFLs are designed to replace an incandescent lamp and
can fit in the existing light fixtures formerly used for incandescents.
The CFLs provide lighting people are accustomed to in their
homes, with the added benefit of long life and lower total
operating costs. They last up to 13 times longer and use
significantly less energy than an incandescent, which reduces
maintenance and electricity costs. Depending on the compact
fluorescent lamp you use, you can save significantly in energy
costs as compared to a standard incandescent lamp. These
lamps also have considerably less greenhouse emissions than
incandescents so they are better for the environment.
The purpose of this study is to research the quality light
output of residential lighting. The residential lighting involve U
type CFLs and twister type CFLs. The quality light output include
luminous efficiency, color temperature, color-rendering index
(CRI) and spectrum. These informations shall provide select
energy saver lamps concepts to consumers. Based on this study,
the authors recommend the high power CFLs in luminous
efficiency. The relation seems not noticeable for CFLs in CRI. The
information can be also an advice to improve for lack of daily
energy saving index of Green Building, except that this work can
be a frame of reference when the government sets up the
relevant polices.
