Comparison of cold cathode lamps and LED lamps

Energy saving (luminous efficiency) contrast to Luxeon for example: red LED, 44 lumens / watt; red cold cathode tube, 18 lumens / watt. Green LED, 30 LM / W; green cold cathode tube, 88 LM / W. Conclusion: red LED lamps are more efficient than red cold cathode lamps.

Comparison of the two theoretical life of LED light source, the life of 100000 hours, if the daily light up to 5 hours, life expectancy of up to 55 years; cold cathode light source, life of up to 30000 hours a day for up to 5 hours of life expectancy of up to 16 years.

Conclusion: due to these two light sources are required for power supply and lamp shell, the existing electronic power supply life and lamp shell life of 10 years, the actual life of these lamps should be in the 10 year of the science of science and technology.

Green LED, 30 LM / W; green cold cathode tube, 88 LM / W.

Conclusion: red LED lamps are more efficient than red cold cathode lamps.

Green cold cathode lamp power saving than green LED lamps.

The same lumen, power consumption is only 10% - 20% incandescent lamp, both are efficient, energy-saving green light source.

Compared with the LED lamp is a low voltage and high current work, the requirements of high moisture resistance; cold cathode lamps because of high voltage and low current work, especially good anti surge performance.

Conclusion: it is necessary to strengthen the moisture proof ability of LED lamps, especially for the wet environment.

Comparison of seismic performance of LED lamps is particularly superior; cold cathode light source is made of glass, slightly worse than the LED seismic performance, but better than other types of hot cathode lamp seismic performance.

Conclusion: both of them are earthquake resistant lamps, which can be used in the places with strong vibration.

Beat color contrast LED light source: can beat, adjust pressure discoloration, and does not affect the product life.

Cold cathode light source: can beat, adjust pressure color, and does not affect the product life.

Conclusion: both can be used in the need to change the beating, pressure regulating color.

Color contrast LED light source color: red, green, blue, white, yellow, color.

Cold cathode light source color: white, red, pink, orange, pink, yellow colored, bright yellow, yellow, green, green, milk, green, light blue, blue, purple, purple, color.

Conclusion: both colors are rich, not only can be used for lighting, but also can be used as decorative light.

Appearance contrast LED light points, can also be connected to the line or surface, the design of large scale, rich lighting.

Because of the shape of the light source, the cold cathode light source affects the appearance of the whole lamp.

Conclusion: LED is a light source, the design scale is larger.

Underwater working performance: LED lamps are generally low pressure lamps, underwater work safety is good, a large number of applications in underwater lights, buried lights, etc..

Cold cathode lamps are generally high-pressure input, not suitable for underwater or ground work.
