Things have changed a lot since then.

As LED manufacturers have increased the efficiency of the bulbs, fewer are required for a given wattage and bulb type and the prices have fallen precipitously. (At Home Depot, Lowe’s and Wal-Mart, for instance, today’s price for a 90 watt-equivalent Par 38 spotlight is $ 20 to $ 30 — 75 to 85 percent less than the one I tried in 2007).

At the same time, the quality of the light produced by today’s LEDs has vastly improved. In my most recent annual home testing, I found that the light produced for most of the bulb categories can be extremely close to that of the incandescent and halogen bulbs the LEDs are designed to replace — so much so that only a lighting expert will notice the difference.

Moreover, the bulbs are so long-lasting — more than 22 years if used for only three hours a day, the average use per bulb per day in most U.S. households — that some manufacturers have incorporated the LED into the fixture itself.
