Conception of  tunnel lighting
An tunnel lighting is an electrondeless fluorescent without electrodes,which relies on the fundamental principles of Electromagnetic induction and gas discharge to create light. The life of the tunnel lighting without filaments and electrodes lasts 100.000 hours which is 100 times of incandescent lamp,5-15times of high pressure electric discharge lamp,and 5-10times of compact fluorescent lamp.

Features of tunnel lighting

1.Low frequency:250KHZ
2. 5 years warranty
3.life time>100000hours
4. CE & Rohs

5.Wide voltage (120-277v\V) / Power range(40W-400W)

6.High luminous efficacy 80lm/w.effective luminous efficacy up to 150plm/w.

Advantages of  tunnel lighting

Energy Saving
Compared with HID lamps,induction lamps save 70% enevgy,similar to new fluorescent lamps of high energy saving,which creat less heat to reduce cooling cost of air anditioning.
NO Maintenance/Less Maintenance
Longer life means reducing replacement.In some cases zero maintenance,is especially great for the areas which are hard to reach and busy such as tunnels,roads ,high bay areas,Ceiling Lights has a wide operating temperature,and is good for emergency and extreme climates.
Healthy,Safety,Environment
No flicker and less glare provide maximum eyesight protection,choice of color temperatures near to natural daylight increases sagety,productivity, performance outstanding color performance for life less CO2 output and no mercury waste to disposion
