low frequency induction lamp feature |
high frequency induction lamp feature |
| Basic features |
external chip structure, convenient for heat dissipation, flexible selection of light tube size and appearance, owing single magnet ring and double magnet ring, large inductance. |
built-in chip structure, inconvenient for heat dissipation, available only with bulb-shaped structure, single magnet chip, small inductance. |
| Wide power range, from 15W to 400W of all light tubes |
Narrow selective power range (differs according to the manufacturer) |
| Provide for clients with various tailoring induction lamps with special specifications(such as 50W、60W、70W、100W、250W, etc). |
Can select special power specifications |
| Low temperature in light tube surface |
High temperature in bulb surface |
| Good starting performance in low temperature |
Relatively poor starting performance in low temperature. |
| Poor electrical equipment matching performance |
adopts specific IC chip, stable frequency setting, can also be adjusted in a wide range |
adopts magnet chip self-excitation category to produce MHZ grade AC output signal and light tube frequency and power may change with temperature altering. |
| Specific IC chip and adjusting technology for flexible dimming |
Difficult to achieve dimming technology. |
| Photometry difference comparison |
Round-shaped and rectangle structures; adopts a tailoring reflector and can be used in various occasions. |
Bulb structure, point light source giving out light, matching up with ordinary lighting reflectors, easier to design reflector. |
| Higher light effect compared with the same power HID lamp. |
Poor light effect compared with the same power low frequency induction lamp. |
