Cheerful LED lighting uses less power and saves money.

Upgrade Bulbs

Replace incandescent bulbs now with LED bulbs, to burn much less power for comparable light.  And replace CFLs when they burn out.​

Modern LED lamps are available in "warm white," "cool white" and "daylight."  Using the same color throughout the room looks best. 

Use this worksheet to calculate how much money and carbon pollution you could save by switching from incandescent or CFL bulbs to LED bulbs.


Ceiling "trough" fixtures still burning 4-ft long, T12 lamps (1.5" diameter) should be re-lamped as soon as practical.  Commercial building operators should consider re-lamping troughs still burning T8 lamps (1" diameter), because L&GE offers good rebates.  


Simply re-lamping to LED T8 lamps makes sense.  Wiring around the old ballast is better.  In some situations, replacing the whole fixture with a model designed for LED lamps can be justified.  

Light Tube

Light tubes direct daylight from the sky through a highly reflective tube into the living or working space.  The light is free and especially beautiful.


All fluorescent lamps or bulbs contain Mercury, a potent neurotoxin. Please dispose of spent fluorescent lamps properly.  Visit HazBin for more info.  Some Home Depots stores also accept spent lamps for proper disposal..
