it’s logically simple… but there are differences… with the heat from glass sealing you can’t put an LED at the end being sealed or it will melt. with chips you can put them on the other end or the middle and it doesn’t matter… but with a dual LED you want one LED at each end really… and this becomes an issue with magnetic rod and insert design… it’s a pain also to try to get engineers to work with assemblers when they aren’t side by side… it’s just… there are issues and we have other things to focus on.
