8. FLUORESCENT TUBES
Advantages
fluorescent tubes tend to be bigger than other individuals but they work quite well.
 Fluorescent tubes give off a lot much less heat than other kinds of lights hence
which means that in hot climates or hot climate you will not get as hot just from the
light getting turned on.
they have a lot longer life span than a number of other bulbs, this life span can last
up to 20 instances longer than the regular equivalent
Disadvantages
if you turn the lights on and off regularly the lifespan of the bulb will be cut
dramatically which can finish up costing you much more money in the long run
shopping for a lot more.
 fluorescent tubes are that they can be a health and safety danger, if they are broken
then they can let out tiny amounts of mercury which can be extremely hazardous.

10. COMPACT FLUORESCENT LAMPS
(CFL)
A compact fluorescent lamp (CFL), also
called compact fluorescent light, energy-saving
light, and compact fluorescent tube, is a fluorescent
lamp designed to replace an incandescent lamp;
some types fit into light fixtures formerly used for
incandescent lamps. The lamps use a tube which is
curved or folded to fit into the space of an
incandescent bulb, and a compact electronic
ballast in the base of the lamp.
 Compared to general-service incandescent lamps
giving the same amount of visible light, CFLs use
one-fifth to one-third the electric power, and last
eight to fifteen times longer. A CFL has a higher
purchase price than an incandescent lamp, but can
save over five times its purchase price in electricity
costs over the lamp's lifetime

11. COMPACT FLUORESCENT LAMPS
(CFL)
Advantages
Energy Star qualified CFLs use at least two-thirds less energy than
standard incandescent bulbs
CFLS can last about 6 times longer (average lifespan of a CFL is five
to six years).
CFLs save Rs. 1800 or more in energy costs over each bulb's
lifetime.
CFLs produce 70 percent less heat, making them safer to operate.
Disadvantages
Skin cancer risk, due to leaking UV radiation, is a concern, which
only came to light (so to speak) in July 2012.
Like all fluorescent lamps, CFLs contain mercury, which complicates
their disposal and if the bulbs are broken indoors, does present a
health risk, especially to small children.

13. LED
Today most efficient way of illumination and lighting, with an estimated
energy efficiency of 80%-90% when compared to traditional lighting and
conventional light bulbs. This means that about 80% of the electrical energy
is converted to light, while a 20% is lost and converted into other forms of
energy such as heat.

14. LED
Basic advantages of LED Light:
Energy efficient - LED’s are now capable of outputting 135 lumens/watt .
Long Lifetime - 50,000 hours or more if properly engineered .
Rugged - LED’s are also called “Solid State Lighting (SSL) as they are made of solid
material with no filament or tube or bulb to break .
No warm-up period - LED’s light instantly – in nanoseconds .
Excellent Color Rendering - LED’s do not wash out colors like other light sources
such as fluorescents, making them perfect for displays and retail applications .
Environmentally friendly - LED’s contain no mercury or other hazardous substances .
Controllable - LED’s can be controlled for brightness and color
LEDs are ideal for use in applications that are subject to frequent on-off cycling,
unlike fluorescent lamps that burn out more quickly when cycled frequently, or HID
lamps that require a long time before restarting .
