Product Description

LED Troffer

The Kobi Electric LED Troffer is the ultimate replacement for fluorescent tubes and fixtures. Troffers are permanent, long-lasting, all-in-one fixtures. They contain no lamps that require replacement. Instead, the LEDs are integrated into the fixture. These LED troffers are designed and manufactured in the same standard sizes as their fluorescent predecessors. The single reflector versions of these troffers offer an updated look and aesthetic to traditional fluorescent fixtures. These LED Troffers are rated at a 50,000 hour lifetime.


  • Eliminates fluorescent lamp and ballast maintenance costs
  • Longer, more energy efficient life than fluorescent T8 lamps
  • Mercury and Lead-free, UV and IR free
  • Instant on to full brightness

 Surface Mount Kits

Surface mount kits are not included with the troffer but are available 2′ x 2′ and 2′ x 4′ dimensions.

Battery Backup Options

IOTA battery backup units are available for purchase and installation on all Kobi Electric LED Troffers.
