Trilux do it! The Lumega! I think Philips should do it and bring back the SGS!

Mainly because LED and HID lanterns have different requirements, an LED only needs to be able to fit a rectangular driver, terminal block, photocell and a surge protector in the gear chamber, as well as a flat LED pannel, with a heatsink on top. This is all very thin, and uses the minimum amount of material for the best performance, whereas a HID lantern body would have lots of wasted space and wouldn't get proper heatskinking while also using more materials, creating a more costly and less reliable lantern.

With that said, Philips did do an LED version of the Selenium and currently make a modified LED version of the Iridium.

Why don't they do the Selenium any more?

Presumably wasn't selling well and was costly to make. As LED technology advanced and they made newer designs, there was no reason to continue the selenium.

Thats just my guess though.

The main design goal with LED lights is to spread the light evenly on the road (that's what sells in the photos, like in the LED vs HPS pictures Max used to upload to the gallery), including in the range where it doesn't even matter anymore

Our vision is capable of handling light level differences of 1000:1, handles easily 10:1, in the HID days 4:1 was considered awesome, but now LED lighting specialists feel the need to achieve <2:1, and screw every other parameter that was compromised to get there. So not much was left besides flat lens panels with a specific lens shape

Then, the "swatter" form factor is about as optimized as it gets to be able to heatsink the LED array of this configuration, with the least amount of Aluminum possible

Any proper optic control at the light source itself, to reduce the luminance, hide the light source above the cutoff line, or provide any sensible cutoff (and not 90deg of basic FCO), got thrown out of the window

The fact that most of the people judge how good a light source is is by its glare (ie more glare - better lighting), and that aesthetic designers get hooked so easily on the "smart" aesthetic of "swatters", don't help here either

SOX lantern as is may not be the optimal in terms of efficiency and glare, especially because it eliminates the cutoff that can already be achieved with the LEDs alone. With SOX lamp the light was not interfering with vision and not causing eye strain even with a bare lamp, the same cannot work for LED without additional optical components under the diffuser

I’m talking about the Lantern shape itself

would love to see autoroute lighting like the old powerlite florescent fittings long and skinny reaching well over the main traffic lanes and not beaming from the side like current cobra head / high mast pizza box shaped units do

As I'm talking about the polish manufactures, I think Elgo Lighting was the only Polish manufacture that designed LED fixtures in SOX and HPS shapes (a few were flat). The Adeco pretty much looked like the Modus LV fixtures, but had a flat glass. Pretty much used LED tubes instead of diodes.

The Astra and the Acron 100 LED fixtures were basically in the design of HPS design. Astra had flat glass, the Acron 100 LED had a shallow bowl.

Take in mind these all fixtures were made in the early 2010s, or before 2016, as in 2016 the whole manufacture shut down unfortunately...

Interesting! I thought Elgo became Lena?

Nope. Let me explain.

The manufacture in 1958 first started of as A-24 Zakłady Sprzętu Instalacyjnego in Gostynin. They made electric installation equiments at the time, like connectors, sockets, and other stuff in the type. At 1961, they started to make ballasts for HPMV, fluorescent, and other discharge bulbs, instead of the electrical equipments. At 1963, they chnaged their manufacture's name to Elgo Gostynin, and continued making the ballasts I believe. In 1972, they incorporated with another manufacture named Polam I believe. By 1978, their manufacture name was changed again, and renamed to Polam Gostynin (reasonable to the manufacture they incorporated with), and designed the first HPS streetlight in Poland, the OUS 400. From that time they started to make streetlights. From 1985, their streetlights were started to be stamped by a new logo, called Polamp. However, as of, the manufacture's name stayed the same. And in the same year, they made the last fixture before in 1990, their manufacture NAME was again renamed to Elgo Lighting. After the rename, they still continued the OUS / OUR 400 fixtures. At the time when the name was Elgo, they made many fixtures, such as the XXXd series in 1992, XXXa series in 1995, XXXe and XXXc series in 1997, and the Acron series in 2008, and many other. At the early 2010s, they started to make LED fixtures of different kinds, some flat, some in HPS shape, and even some in SOX shape like I mentioned. At early 2010s, some HPS fixtures were still made and some were new. In 2016, the manufacture I believe bankrupted and had to close down forever and ever...

And that's the story.

Oh ok! Well that is very interesting!
