The popularity

 

The quality of light we work and live under can affect the way that we feel.
It is best to fit CCFL lighting in areas where people work and live.
LED is best suited to areas where people don’t spend a lot of time.
For example, hallways of offices and hospitals, warehouses and parking lots.

Light distribution

LED lamps emit light in mostly one direction. Because of this, the luminance (Lx) is strong directly under the fixture, but it does not luminance a wide area. Therefore, placing it in the same way as a common fluorescent light for indoor lighting will produce shadows and unbalanced lighting. This is why LED lights give the impression that they are somehow "glaring but dark..."

There is no point in having a light that is
bright only directly under the lamp for indoor lighting.
A wide, uniform light distribution is preferable. This is CCFL.

Natural light

Most lights that use LED lamps produce a "pseudo-white" color, which is created by combining a blue LED with yellow phosphor. That is why the color looks yellowish and unnatural. The color rendering index (Ra) is poor (around70), which means that there are some colors that LED cannot reproduce.

CCFL on the other hand is a 3-band light source just like fluorescent lights and is used for backlights in LCD TVs. It is acknowledged worldwide for its ability to reproduce color accurately. And its high color rendering index (86 or more) means that it produces no glare and does not irritate the eyes.

For lightning used daily in the office or living space,
a natural light that causes no irritation is best.

Temperature

LED brightness can be increased by boosting the amount of power supplied; however, this also increases the amount of heat generated. And this buildup of heat can shorten the lifespan of LEDs.

Therefore, to prevent this, a heat sink or external power supply is needed, and care needs to be taken when using them under high temperature conditions. CCFLs generate no more than 70-80° C of heat, lower than LEDs. Because no special heat management measures are needed, it provides a stable light even in high temperature environments.

Blue light hazard

At night, light throws the body's biological clock the circadian rhythm out of whack.
Sleep suffers. Worse, research shows that it may contribute to the causation of cancer, diabetes, heart disease, and obesity.

But not all colors of light have the same effect. Blue wavelengths which are beneficial during daylight hours
because they boost attention, reaction times, and mood?seem to be the most disruptive at night.
And the proliferation of electronics with screens, as well as energy-efficient lighting,
is increasing our exposure to blue wavelengths, especially after sundown.
As LED is predominantly emitting Blue Light there is evidence that this light can cause macular degeneration
affecting the retina and eyesight can decrease. Such results have been published by many credible research sources.

Flickering protection

The current waveform of a the normal LED light (see waveform on right below),
repeated 100 times may cause flickering with our eyes.
It possible to take measures with LED to lessen this effect however,
because the CCFL illumination uses a high frequency inverter, there is no such effect to eyes.

Light source

LED (light emitting diode) is a semiconductor device.
The light source is a point light sourcelike a high linear beam.

CCFL (cold cathode fluorescent lamp) looks like
a thin glass tube. It is a linear light source and,
along with fluorescent lamps, belongs to the electric
discharge lamp family. Its internal structure is
very similar to fluorescent lamps.

Fewer Insects

Because CCFL does not emit UV (ultraviolet rays), insects are not drawn to the light.

CCFL Won’t Break

The fluorescent tube of Solana is made from polycarbonate. If dropped, the polycarbonate finish will not break or shatter like a fluorescent lamp. Even if driven over by a car Solana CCFL remains in tack.

Lifespan

CCFL illumination /LED illumination lamp has longer lifespan more than 5 times from fluorescent lamp.

*1 Calculate it as a test at 50% of survival rates
*2 When turned on & off three times per day the life is up to 15,000 hours. If turned on & off seven times per day the life will reduce to around 10,000 hours.

Energy saving

When compared with a fluorescent lamp Solana CCFL achieves an energy saving between 25-53%!
[ Total consumption electricity when compared to electrical ballast including the inverter ]

*1 Total consumed electricity when compared to a fluorescent lamp with ignitor.
*2 A 2200lm was used for this test

So where does CCFL lighting work best versus LED lighting?

CCFL lighting

CCFL is most suitable for places
where people work or live.

  • Office

  • Apartment

  • Commercial
    facilities

  • Hospital

  • School

  • Convenience
    store

  • Poultry farming

  • and more

LED lighting

LED is most suitable for the places
where people DON’T work or live.

  • Backyard

  • Corridor

  • Warehouse

  • Signboard

  • Restroom

  • Streetlamp

  • Parking lot

  • and more
