RETROFIT T12, T8 and T5 FLUORESCENT FIXTURES including T8 and T5 high bay fixtures
2', 4', 6' and 8'

  • AEFDirectConnectLED        units wire to incoming line power and then
    ​plug into the side of the LED unit.
  • LED unit magnetizes to the top of the fixture.
  • Fast and simple installation time of approx. 3-5 minutes.
  • Multiple units connect together using shorter jumper whips.
  • Existing fixture ballasts are bypassed and not reused as they are in some of the other instant fit LED units.  
  • No worry about existing ballast condition or eventual replacement which adds to long term costs.
  • Lamp holders do not have to be replaced as you have to do with other LED units because they are broken or shunted (existing T8 fixtures).
  • Up to >185 lumens per watt allows de-lamping - saving a tremendous amount of money on energy use, labor and additional product costs.  (most on the market are >110 lm/w if they are DLC certified = not enough light to enable de-lamping in most cases)
  • Daisy Chain end to end fixtures or within a fixture - available on all models (up to 240')
  • Installation time is less than half of other retrofits

  • Highest lumen per watt packages
  • Existing ballast is disconnected
  • Safest retrofit in the industry
  • ​3 to 5 minute installation
  • CRI 85
