1. Comparison of theoretical life of the two
The LED light source has a life of 100,000 hours. If it is lit for 5 hours every day, the life span can reach 55 years. The cold cathode light source has a life of 30,000 hours and a life of 5 hours per day for up to 16 years.
Conclusion: Since both sources require power drivers and luminaire housings, the current electronic power supply life and lamp housing life is 10 years, and the actual life of these two luminaires should be scientific for 10 years.
2, energy saving (lighting efficiency) comparison
Take luxeon as an example: red LED, 44 lumens / watt; red cold cathode tube, 18 lumens / watt. Green LED, 30 lumens / watt; green cold cathode tube, 88 lumens / watt.
Conclusion: Red LED lamps save power compared to red cold cathode lamps. Green cold cathode lamps save power compared to green LED lamps. The same lumens, power consumption is only 10% - 20% of incandescent lamps, both are efficient, energy-saving green light source.
3, moisture resistance performance comparison
Due to the low-voltage and high-current operation of LED lamps, the requirements for moisture resistance are relatively high; cold-cathode lamps work well because of high-voltage and low-current operation, and the moisture resistance is particularly good.
Conclusion: It is necessary to strengthen the moisture resistance of LED lamps. Cold cathode lamps are especially suitable for humid environments that cannot be used by other lamps.
4, shock resistance comparison
The LED lamp has excellent seismic performance; the cold cathode light source is made of glass, which is slightly worse than the LED, but superior to other types of hot cathode lamps.
Conclusion: Both are anti-vibration lamps, which can be used in places with strong vibration.
5, beating color contrast
LED light source: It can be beaten and pressure-regulated without affecting product life. Cold cathode light source: It can be beaten and pressure-regulated without affecting product life.
Conclusion: Both can be used in places where there is a need for beating changes and pressure modulation.
6, color contrast
The color of the LED light source is: red, green, blue, white, yellow, and discolored. The color of the cold cathode light source is: white, red, pink, orange, peach, yellow, bright yellow, milk yellow, green, green, blue, light blue, blue, purple, purple, and discolored.
Conclusion: Both colors are rich, not only can be used as lighting, but also can be used as decorative light source.
7, appearance comparison
The LED light source is point-shaped, and can also be connected into a line or a surface. The design scale is large and the lamp shape is rich. The cold cathode light source affects the appearance of the entire luminaire due to the shape of the light source itself.
Conclusion: LEDs are light source lamps with a large design scale.
8, underwater performance:
LED lamps are generally low-voltage lamps, which have good safety in underwater work, and are widely used in underwater lamps and buried lamps. Cold cathode lamps are generally high voltage inputs and are not suitable for underwater or ground work.
