LVD vs HPS:

Comparison between Low Frequency Induction Lamp and High Frequency Induction Lamp:

Item	Low frequency elctromagnetic induction lamp	High frequency elctromagnetic induction lamp
Frequency	250Khz	2713.6Khz
Since radio`s frequency is 150Khz-30Mhz, the low frequency than that can not over pass its
Luminous effeciency	85Lm/W	60Lm/W
With the same wattage, low frequency lamp`s luminous efficiency is 25% higher than high frequency lamp`s
Wattage(W)	15-400W	20-160W
Low frequency induction lamp can reach 400W, which can replace 800W MHL on the basis of keeping the same color rendering
Heat dissipation	Good	poor
EMC/EMI Testing	Can pass	Can not pass
Then many country forbidden high frequency lamp
Outlooking	Round&rectangular	Bulb
Mount into fixture	Need special fixture	Easy to mount into traditional fixture
Quality guarantee	5years	3years
Coupling method	Outside	Indide
Magnetic core temperature	About 350℃	About 160℃
