The comparison of traditional lamp with LED lamp
Type	Traditional lamp	LED  lamp
light degradation	3000hours 20-35%	10000hours 8%-10%
Lifespan	Less than 8,000 hours	20000hours to 50000hours
Actual power consumption of the light	40W	16W
Principle of light	High-voltage , need warm light	Low current , instant, no need  warm lights
Driving Mode	driving AC3000-700V	drivin g AC220V
Spectrum	With ultraviolet	It does not hurt the skin without UV
CRI	70%-75%	70%-85%
Environmental protection	Mercury and heavy metals, can not be recycled	Semiconductor chips, recyclable, non-radiation
light pollution	Severe light pollution, harmful to plants and animals	Cold light source, not harmful to animal and plant
Consumption	Require large square cable, high cost	Just a little square of cables, to avoid waste of resources
The strobe of the light	High frequency driver with stroboscopic phenomenon	DC drive, no strobe
Working stability	Peak voltage (250V),The working voltage changed with the the power to when  reduce the light intensity then increase power consumption, light life will reduce and the light degradation increases	current protection design and regulator design, light brightness stability does not change with the grid voltage, longspan will increase
Year consumption	40W*12H*365/1000=175.2Degree	16w*12h*365/1000=70.08Degree
cost	0.2usd*175.2degreer=35.04usd/year in UK	0.2usd*70.08degree=14.02usd/year in UK
Effective energy conservation	1: Save 105.12 degrees/year for each lamp. 2: reduction of carbon up to 75.8 kg 3: Save money 21.02usd/year for each lamp
