I believe it is only important to NOT touch the glass on a bulb that gets really hot, like a halogen bulb. On these regular incandescent bulbs, I doubt that touching the glass will degraded the life of the bulb. BTW, the issue is getting finger prints/oil on a bulb.

Hello. Yes, exactly correct. Try to avoid touching the glass part of the bulb. Although, I’ve never seen any data on fingerprints degrading the life of the bulb. Have you? It’s mostly a good best practice passed down generation to generation as far as I can tell. I’m sure there’s good reason for it, but I’d love to see an experiment. Thanks for the tip!

​@@FastFixRUclips I have not seen data showing that fingerprints degrade the life of a light bulb. However, as a mechanical engineer, I used to work on the manufacture of radar systems (for Varian Associates) for all sorts of military aircraft, ships, etc. The portion of the radar system, the vacuum tube, that emits electrons to generate the radar signal, was very susceptible to contamination by finger prints during the manufacturing process. During the manufacturing process (during final assembly), these radar tubes had to be pumped down (in a cleanroom environment) to a very high vacuum and then sealed for the life of their operation. The presence of a single small finger print was a major source of contamination on the inside of a vacuum tube. The higher the vacuum, the more that little fingerprint would give off gases that would make it very difficult to achieve the proper vacuum. If such a small finger print can be so catastrophic for the proper operation of a robust radar system, I find it very plausible that it could shorten the life of a hot light bulb.
BTW, a finger print is composed of the following:
> Na+ (sodium) and Cl- (chlorine) ions
> Proteins and amino acids
> Lipids (natural oils, waxes, and steroids)
> Water
> Plus, any other contaminants that are on a finger from the environment
