Description:

lotus energy saving lamp-8W

1.)Save 80% energy more than incandescent lamps;

2.)Tube adopts pure tricolor phosphor powder,

3.)Power Factor (P.F):0.6 or 0.92,

4.)All the lamps are in 8000hrs,

5.)Warm white and cool white or daylight available.

Benefits:

1.) High efficiency: A 22W energy saving lamp has about the same light as a ordinary lamps with 100W,

2.) Environmentally Friendly: Reduce the pollution, reduce the energy consume. The long lifespan can also reduce waste of unprocessed materials.

3.) Lifespan: To use 1 CFL is equal to 6~10 common lamps,

4.) Economical: CFL can save the energy. The long lifespan can reduce the cost of buying lamps.

Definition:

A compact fluorescent lamp (CFL), also known as a compact fluorescent light or energy saving light (or less commonly as a compact fluorescent tube), is a type of fluorescent lamp. Many CFLs are designed to replace an incandescent lamp and can fit into most existing light fixtures formerly used for incandescents.

Benefits:

1.) Cost: Compared to general service incandescent lamps giving the same amount of visible light, CFLs use less power and have a longer rated life. Although, a CFL has a higher purchase price than an incandescent lamp, but can save over US$30 in electricity costs over the lamp's life time. Like all fluorescent lamps, CFLs contain mercury, which complicates their disposal. For a given light output, CFLs use 20 to 33 percent of the power of equivalent incandescent lamps. Since lighting accounted for approximately 9% of household electricity usage in households, widespread use of CFLs could save as much as 7% of total US household usage. While the purchase price of an integrated CFL is typically 3 to 10 times greater than that of an equivalent incandescent lamp, the extended lifetime and lower energy use will more than compensate for the higher initial cost. A US article stated "A household that invested $90 in changing 30 fixtures to CFLs would save $440 to $1,500 over the five-year life of the bulbs, depending on your cost of electricity. Look at your utility bill and imagine a 12% discount to estimate the savings."

CFLs are extremely cost-effective in commercial buildings when used to replace incandescent lamps. Using average U.S. commercial electricity and gas rates for 2006, a 2008 article found that replacing each 75 W incandescent lamp with a CFL resulted in yearly savings of $22 in energy usage, reduced HVAC cost, and reduced labor to change lamps. The incremental capital investment of $2 per fixture is typically paid back in about one month. Savings are greater and payback periods shorter in regions with higher electric rates and, to a lesser extent, also in regions with higher than U.S. average cooling requirements

2.) Life Span: The average rated life of a CFL is between 8 and 15 times that of incandescents. CFLs typically have a rated lifespan of between 6,000 and 15,000 hours, whereas incandescent lamps are usually manufactured to have a lifespan of 750 hours or 1,000 hours. Some incandescent bulbs with long lifetime ratings have been able to trade efficiency for lifespan, slightly reducing light output to significantly improve the rated life.

3.) Starting Time: Incandescents reach full brightness a fraction of a second after being switched on. CFLs turn on within a second, but many still take time to warm up to full brightness. The light color may be slightly different immediately after being turned on. Some CFLs are marketed as "instant on" and have no noticeable warm-up period, but others can take up to a minute to reach full brightness, or longer in very cold temperatures. Some that use a mercury amalgam can take up to three minutes to reach full output. This and the shorter life of CFLs when turned on and off for short periods may make CFLs less suitable for applications such as motion-activated lighting.

4.) Versatile: CFLs can be applied nearly anywhere that incandescent lights are used. Energy saving lamps can be used in recessed fixtures, table lamps, track lighting, ceiling fixtures and porchlights.3-way CFLs are also now available for lamps with 3-way settings. Dimmable CFLs are also available for lights using a dimmer switch.

How to choose CFL:

1.)    Choose your preferred light quality,

2.)    Energy saving lamps have a “K” figure listed on the packaging, CFLs with “K” letter between 2700~3000 give off a soft bright light like incandescents. CFLs with “K” figure between 3500~6000 give off a bright light. As you go up the “K” figure scale the light gets bluish and closer to daylight.

For example:

Approx: 2700K=warm white (looks just like incandescent)

Approx: 5000K=cool white (white/blue, bright light)

2. Choose the shape: CFLs are available in a variety of shapes to fit a range of lamps and lighting fixtures.

CFL Models: spiral lamps, triple tube lamp, standard lamps, global lamps, flood lamps, candelabra

3. Match lumens to the incandescent being replaced. Lumens indicate the amount of the light being generated.
