The more I drive the areas of LED installations, the more I see failures around.

It’s not the feed cables is it?, when we first lost vast rows of our HPS for Urbis’s Ampera LED, within 3 weeks about 15 of them had gone out, something I found quite amusing!   ;D, turned out in the end to be a faulty underground supply cable though! And as much as I dislike the Ampera, to be fair to Urbis, it wasn’t their lanterns!

In my area, LEDs are only installed on CalTrans maintained roads, and they use the Leotek ECobra. Almost all of them have failed and the rest turned yellow from heated plastic.

I’ve always been interested in all kinds of lighting, mainly incandescent and HID, and especially all kinds of sodium lamps (HPS/LPS). I’ll tolerate LED but I’m not a fan of it.
I’m not proud to say that my city has Devolved to LED.

Here in my region there is apparently one LED installation with bad accessible failing street lights. They are mounted between two lanes on a highway feeder road. Some of them start to blink and some do not work at all. All these lights in this feeder are made by a certain manufacturer in Germany and these are the only professional LED street lights which are failing in vast numbers. All other lights which we use around the city are made by Philips (Signify), Osram-Siteco and ASElight and they are doing well so far.

Yes all the lights run under the manufacturers warranty. I’m glad that these are not our lights.

When did they dump Leotek? I remember last year near my area a GE M-400A 310w HPS was replaced by a Leotek GC2.

For having dumped them, i sure see a lot of brand new Leotek fixtures pop up on Caltrans owned poles (most recent one being installed 2 or 3 weeks ago).

Maybe they're using leftovers? I remember Caltrans installed a brand new GE M-400A 250w HPS light at a intersection last year on Route 66 in my area when the pole (with a GE ERS1 LED) got knocked down. Surprising since the rest of the intersection is LED!

Most of the fixtures are being installed as a part of the FasTrak projects (so a 100+ fixtures or so).

Yes, they were using leftovers. I still see a few pop up as replacements here and there. Also contractors still sometimes install them in construction projects.

Contractors have specs they are bound in contracts to abide by and those specs may allow them to use other manufacture's fixture.

I haven't seen TXDOT using LeoTek LED fixtures. Even though its in the catalogue of the Roadway Illumination Supplies. But however, their GreenstarLED Avenger fixtures are crapping out within a few months. One of their high output fixtures used on freeways one of them have only one LED module working and the rest are out, since theres four modules in the high output version.
