Review on Qoope Super Bright 921 LED Bulb Non-Polarity 912 LED Backup Light Bulbs 45-SMD 4014 Chipsets Canbus Error Free T15 906 W16W LED Bulb For Back Up Lights Reverse Lights by Chad Mills

Revainrating 1 out of 5

Didn't last 90 days

*Edited to add* Sections of all 5 bulbs have already burned out in less than 90 days, stable 12vdc power supply. My 30 day guarantee has expired so I cannot return. Might be ok for automotive applications where the bulbs run a few seconds at a time, but not if the bulbs need to run for several hours a day. I used some old landscape lights that were designed for incandescent bulbs. Driving with 12V DC power pack. Much brighter than low voltage incandescent bulbs but not 1220 lumens. A 12 V DC switching power supply consumes 25 W to operate 5 lamps and has an efficiency of approx. 80%. So each bulb draws about 4W at 12V. I give them 350 honest lumens. Non-polarized is a good feature, plug and play.

Pros
  • That's great
Cons
  • Short manual
