Fluorescent Lighting Retrofit Kits

Is it time to update your lighting? For a quick return on your investment, retrofitting T12 lamps and magnetic ballasts with high efficiency electronic ballasts and T8 lamps is an energy-smart choice.

Retrofit advantages

  • It’s less expensive than buying all new fixtures (including labor) 
  • When you upgrade to T8s you may need fewer lamps. By delamping, you cut your energy costs even more. 
  • Retrofitting produces less waste than tearing out the entire fixture 
  • Alliant energy offers rebates ranging from $7 to $40 on retrofit kits

Comparison pricing example:

2 foot, 2 lamp replacement -

Fixture cost = $120 - $10 rebate = $110 final cost
