Tunnel lamp series of tri-phosphor oblate leaf lamps

8. It is not suitable to open lamp of normal temperature and it has more excellent brightness in sealed street lamp fixtures.

7. It can start reliably when temperature is .

6. Its current is 1/6 or 1/7 of equivalent substitute high-voltage sodium lamp and new project can save 50% of cable investment and decrease capacity of assorting electric devices.

5. Constant power output characteristics can avoid prodigality caused by super-brightness when voltage of high-voltage sodium lamp exceeds 220V.

4. It has high power factor (which is 0.99), low harmonic wave, resistance interference EMC design and low loss of non-efficacy.

3. It has more vision view, larger view and quicker reaction rate to obstacles. 

2. Energy can be saved by more than 50% if adopting tri-phosphor oblate leaf street lamp not high-voltage sodium lamps of equal brightness.

1. It can match various existing street lamp caps and meet various requirements of lighting standards of tunnels.
