FLUORESCENT TUBESAdvantages

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.

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

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.

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.

LEDBasic 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 .
