I chose halogen lights because that's what was available at the time and while halogen light bulbs are physically hotter when they turn on they are more energy efficient than incandescent light bulbs. I also hoped that the halogen light bulbs would last longer than the incandescent light bulbs that came with my house and replaced as they burned out with CLFs. LED light bulbs were extremely expensive and not widely available at the time.
That didn't seem to be the case.
Any time I turned on the lights and wondered why it was still dark in the office, I'd see that one or more halogen light bulbs burned out. This happened much more often than in other rooms of the house when I switched over from my CFL light bulbs as they burned out to LED light bulbs now that they are cheaper and more widely available.
I figured it was time to upgrade my halogen desk lamps (that I still like) to LED desk lamps because this constant bulb changing was getting annoying.
Unfortunately, most of the LED goose neck desk lights I found used a permanent LED light bulb which after 10 or 13 years is going to burn out and I'd have to get rid of four lamps instead of four measly light bulbs.
