1. As you replace your old lighting, start with the highest-consuming fixtures first (longest-on, and highest-wattage). Keep color consistent throughout your living areas: most people are happy with a color temperature of 2800K. Make a note of the wattages in each fixture, and take a picture of each. Work with a knowledgeable vendor who will guide you to the right product for each space.
2. Go  here for stores that participate in the MassSave program. MassSave buys down the cost of many light bulbs and fixtures at these Massachusetts hardware stores, so you get instant price discounts. Or you can buy online at the MassSave store AND/OR, sign up for a free Mass Save energy audit - check that out  here , and in the process LED bulbs are installed for free!

Not all Energy Star LED lighting products are the same. Choose the highest efficiency (lumens per watt), and the lowest wattage. Residential Energy Star LED fixtures can vary in efficiency by 50-80%. These figures aren't always obvious, so be a careful shopper. 

Quality LED fixtures are more efficient than using replaceable light bulbs and can lead to dramatically low energy consumption. A residential ceiling-mounted fixture that uses 120 watts of incandescent or 26 watts of compact fluorescent (CFL) can be replaced with a 12 watt LED fixture.

Recessed cans provide a great opportunity for energy savings. Retrofits can bring the LEDs near the surface, reducing light lost in the fixture. A recessed light that used 65W of incandescent or 15 watts of compact fluorescent lights (CFL) can today be replaced with 10W of LED.Dimmable LED fixtures can lead to especially low energy consumption.
