In the lighting world, there are few bulb configurations as popular and widely used as halogen PAR38 bulbs. These sturdy and versatile lamps have found their way into just about every location in our modern lives. We use them in businesses and homes, inside and out. We love our PAR38 light bulbs—but we hate to pay for all the electricity they use. Another problem with them is that after July, standard halogen PAR38 bulbs will no longer be available in the United States thanks to the next round of light bulb bans. Although they have been a long time coming, there are now several LED options available, some of which you would actually consider buying.

The other day I found myself at a loss in the light bulb aisle of my hardware store. I might as well have been shopping for a carburetor. There were too many options with too many symbols and verbiage that I couldn’t decipher (LED, CFL, halogen, lumens, Kelvin, CRI), not to mention all of the various brands (GE, Philips, Cree, EcoSmart — each with its own packaging lingo). Since when do you need an electrical engineering degree to buy a light bulb?
