I had to replace my light on my work bench- the old one quit working. Turns out it was the starter, not the bulb, and no way to get new starter. So had to replace the whole lamp. It was one of those magnifier fluorescent jobs with a circular bulb surrounding a big magnifier. It was also positionable, counterbalanced with knobs to adjust positioning.
I had another lamp next to my bench that I used for a couple of days until I got a new lamp. In that time I was very aware of not having an ideal light. I was doing a lot of photo etch placement, and some air brushing. Got to realizing that the lamp on my workbench may well be my most important tool for model building. I maintain you cannot do a really good job of modeling, and especially painting, unless you have good lighting in more modeling area. Checked with a couple of modeling friends, and they agreed with me.
That was a replacement for a lamp just like it that I bought only two years ago. The previous one lasted about forty years!
