Multiple-layered LED alarm light is designeb,that is with red, yellow, green, blue, white colors. By using fixed current drive, our products have a steady brightness even with varying voltage,which increases LED lifespan.A unique protection circuit prevents LED Lights from power surge, unstable voltage, and sudden power failure. Our products have passed insulation tests,lighting for machinery display and parking lot.

1. Exclusive  type lamp shape featuring an internal curved mirror, LED light can be converted into a surface light source to reduce glare problems  increased viewing angle.
2. Compact design can save space.
3. Another diffusion patterns, reticle in reflex surfaces, which allow light generated from refraction through the shape, so          that the light-emitting layer having a uniform light emission.
4. The base uses a polycarbonate resin, with heat resistance, cold resistance, transparency and so on.
5. The LED module can be varied freely, when the customer needs to replace the light colored layer.
6. Buzzer resonance design, beeper volume increases, the volume up to 70 to 85 dB (measured at one meter), even in a        noisy factory can also be used.
7. Has achieved CE / FCC / PSE certification. And has completed the vibration test, insulation resistance test, and other       tests.
8. Can be directly controlled by the PLC.
