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
