This Act On Energy/EFI store is exclusively for the customers of Ameren Illinois, with order delivery restricted to the Ameren Illinois service territory. Distributor discounts and product rebates from the Ameren Illinois have already been applied to the net product prices shown here.

Ameren Illinois is offering several unique residential programs to help customers use less and spend less on energy. Through this EFI online store, you may order specially priced LED and compact fluorescent light bulbs (CFLs) to meet a variety of lighting needs in and around your home. To order, click here.

Although the purchase price of CFLs is slightly higher than for incandescent bulbs, the real cost of a light bulb is not what it costs to buy, but what it costs to use. Since CFLs use two-thirds less electricity than incandescent bulbs to produce the same amount of light, your electricity savings will easily exceed the purchase price difference. And with the discounts now available, it will cost you even less to start using less and spending less on energy!
