1. longer life than fluorescent tube: min 4 years
　

2. 70%~80% energy-saving over fluorescent tubes
　

3. solid state, high shock/vibration resistant
　

4. work with ballast or without ballast
　

5. no RF interference
　

6. no flickering
　

7. instant soft-start
　

8. minimum maintenance costs
　

9. produce little heat
　

10. no mercury and other hazardous materials, fully RoHS-compliant
　

11. continuous operation for white leds (10 years for other colors)
　

12. rated to operate from -40°F to 122°F [-40°C to 50°C], perfect for environments with extreme climates
　

Application:
　

Quasar led tube competitor's similar product
　

Acrylic front cover: never get broken easily glass tube: get broken easily
　

Work in two modes: with ballast or without ballast work without ballast only
　

Use smd led with best lumen maintainance use through-hole led's with high light degradation
　

Warranty: 3 years no concrete warranty
　

No hazardous materials & fully RoHS-compliant not RoHS-compliant
　

Advantages over competitor's led tubes
　

Glass tube: keep all heat inside the tube, and kill led's prematurely
