Here is e.g. a cylindrical shape,
and here a roundish bead, which should fit better in size. The sticking point here is that the LED also has to fit into the bead, which is why only the smallest types 0401/0402 with dimensions 1.0 mm x 0.5 mm x 0.5 mm (LxWxH) are suitable for this. Then I still found this smaller bead, which fits even better with this lamp shape without reflector. And with that I want to content myself for today.

No detail is spared from your eagle eye Manfred. Never occurred to me that the model will be lighted. Looking forward to the day when the lighting brings the model to life.

Thanks elliott,
I don't know since when you're following my construction report, but I was already working hard on the Lighting chapter three years ago when I did a lot of extensive analysis, as one can see here for the RSS. Source: NASA I can still remember very well how I have rubbed my eagle eyes at that time ... Here is another amazing impression of the Pad at night, showing Challenger's countdown for mission STS-41B (1984). Source: NASA But until then there is still a long and challanging way to go ...

Hi Becky, and thanks for looking in on me,

Hello everyone,
today I have first expanded a handful of the larger ferrules (1 mm²) with a center punch from 2.3 mm to 2.8 mm diameter, for which the cordless screwdriver only needs to run a few revolutions, otherwise one is fast at Ø 3 mm or more. Then I experimented a bit further and tried to expand also the slightly smaller ferrules (0.5 mm²) to Ø 2.8 mm. At this sleeve, the smaller diameter of the tube with 1.4 mm is still slightly smaller than that of the larger ferrule with 1.8 mm, which would fit much better to the socket diameter of my lampshades. The only question was whether the sleeve would endure the expansion, or whether the lampshade would crack. On my first attempt, I was probably a bit too impetuous, which can be clearly seen on the cracked lampshade on the right in the picture. To the left are the expanded 1 mm² ferrules, which did not mind this expanding. Therefore, I proceeded much more cautiously on the second attempt and checked the lampshade diameter from time to time with the caliper gauge. Everything went pretty well up to Ø 2.5 mm, as you can see here, but at Ø 2.8 mm the first mini-cracks appeared on the edge of the lampshade, which is why I will rather use the larger ferrules. And here's already a look ahead to the mainly installed lamp shape on the RSS, here on Pad 39B during the preparation of the Challenger on her last, unfortunately fateful mission STS-51L (1986). Source: forum.nasaspaceflight.com (James MacLaren) And here are my first attempts compared to a simple lamp from the Revell Kit (right). Probably for these lamps thin brass tubes will later be used into which the LED wires then will be threaded respectively soldered.

Your lamp looks so much better than the Revell lamp that there's really no comparison at all Manfred. Good job!

Thanks elliot for your nice compliment,
regarding the Revel lamp, I fully agree with you, that is more than modest.
