If you still get Bayonet Cap style bulbs, the two points can be soldered to the pads directly.

But best still is just to get a proper base of some sort to plug/screw them in - safer, easier to replace, although more bulky and perhaps more expensive.

John,

I'm surprised that you can still get incandesant bulbs. They are becoming increasingly difficult to obtain in the UK and if you do get some they are very low quality and do not last very long. I am beginning to run out of them and will have to start using more LED bulbs sometime in the next few years.

Great design John.

I would add something between the bulb and your desk. If it gets hot it could scorch your finish.

John,

Very clever usage of PVC for your light load project. Just a thought, but you could use a PVC end cap, with a small hole drilled in it, to insulate/protect the base of the bulb (or back fill with RTV). I love the use of the old iron as a higher power load.

Your creativity always amazes me.
