From the article above "LED tech has advanced beyond this 2015 model shown, but in many cases the housings still look like this."
Fortunately many do not - and the housing has little relevance to the chip type and location, or the shielding.
You will find that many now have a smaller and narrower chip to mimic the location of a halogen filament, with a designed in shroud wrapping around the low beam chip. I'd suggest that NONE of the LED bulbs produced in 2015 are still in production - or if they are, sell only to the uninformed buyer.
My first LED bulbs from 2013 have long been replaced by improved versions with minimal scatter. Manufacturers have found that they needed to continually upgrade their product or else their sales would stall as competitors brought out new and improved versions. Every year or so older versions mostly disappear as new versions are released, except for a few budget priced older designs.
Sorry but I dispute, from personal observation and trial, this journalists opinion.
