​* DLC Retrofit kit part number Lm/w and delivered lumen values were determined upon testing completed in a reference fixture

** Lumens per watt are per DLC (Total lumens are nominal wattage x lumens per watt - actual total lumens may very slightly)


  • Patented magnetic attachment system
  • Optional mechanical attachment
  • Ability to de-lamp - no kits needed for positioning
  • Patented Daisy Chain solution to 240'​
  • Quick disconnect

  • DLC Premium: Direct Linear Ambient Luminaires and Linear Retrofit Kits to maximize rebates and reduce wattage. Lower ROI's.
  • Up to >185 lumens per watt allows delamping-saving a tremendous
    amount of money on energy use, labor and additional product costs.
    (many on the market are >110 lm/w if they are DLC certified but
    not enough light to allow delamping.
  • AEFDirectConnectLED     power whip wires to incoming line power and then clip into the side of the LED unit.
  • Magnetizes  or mechanically attach to the top of the existing fixture.
  • Clip in jumper whips from one unit to the next Daisy Chaining up
    to 240' (wiring only once-considerably reduces install)
  • Fast and simple installation time of approx. 3-5 minutes. 
  • 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).
  • No "kits" needed to retrofit 8' fluorescents-magnetize to fixture.
  • Installation time - possibility of cutting in half.
