And Ge would be the Bugatti of street lighting

Ummmmmm.

Don't forget Cree Lighting, they make decent LED fixtures too (none of the XSP's around me installed in 2016 have failed or color shifted) and the XSP's actually look good.

In contrast, the Leotek ECobras installed around the same time (2015-16) are dim, failed or color shifted to a weird 2600k...

Yeah, the XSPs around here have held up well from 2014.

Yeah, I can't say I'm surprised about the GCJs being garbage.

In the case of Cree's XPS series LEDs, I've only ever seen one (partial) failure out of hundreds I've seen, SVP recently started installing XPS series fixture on intersections. On the other hand, Cree's LEDWay High Output series LEDs, which use the same LED modules as the XPSM and XPSL fixtures, seem to be just as bad as Leotek's GCM series LEDs. As I've seen close to a dozen fail just 2 to 3 years after installation, either suffering from dead LEDs, strobing, or both.

I'll have to get you folks some photos of some of the fixtures down here in Colorado Springs.  Not sure if they are Keotek or Cree, but they have certainly color shifted BAD since install, unless it was the intended color.  They look like a Mercury Vapor green now. 

The utility that serves my area has been replacing the E-Cobra in mass due to the issues mentioned above. They're being replaced mostly with the latest offering from Leotek...hope they last.

Sounds like the old Ruud / Cree LEDways, the ones up in Los Angeles had turned a pale green color after 6 or so years.

Well, does the issue still persist?

When I was in So Cal not too long ago I saw an unbelieveable sight, a pair of Leotek E-Cobras working PERFECTLY (no color shifted or purple LEDs, perfect 4000K color temp) in Palm Springs.
The rest of them (especially the CalTrans owned ones) had color shifted or burned out LED modules (a few were also completely out).
In contrast, the AEL, Solarmax, and some no-name Chinese ones around San Diego and on I-10 were all working perfectly.

Most of the Leotek AR-18's in Boston have yellowed out and many of the Leotek GCM2's on Storrow Drive have yellow doors.

Well, does the issue still persist?

All the issues are going strong. GCMs, GCJ, E-Cobras still suck. Only time will tell if the GCM2 and latest GCJ are any better. Most of the cities that bought them are assuming getting warranty coverage.

Now the Cooper Verdeon, well isn’t safe either (2017+). Diodes turning orange followed by total failure. So the Verdeon, Navion, and Archeons are junk as well. More on that in the future,

They're all non-servicable junk, no matter when they were made. By the time the engineers work out the issues, we'll be moving on to the next lighting technology...

@LightsoftheWest: I'm not really sure. Most places that have had the E-Cobra for a couple of years or more from what I've seen have dimmed and have an ugly yellow color, while places that have had the GreenCobra for a couple of years or more are starting to turn a little bit yellow, but that color is still a lot more pleasant to look at than the E-Cobra.

@HIDLad001 - Those E-Cobras are new spot replacements if they are CalTrans owned. I've seen a few pop up recently on their system. They still mainly use SMXs for spot replacements though.

@Econolite03 - Interesting, I haven't seen that happen around here with the Verdeons, but then again, there aren't many around here to begin with. The only places I've seen the Verdeon is Rancho Cucamonga and CalTrans, which doesn't have many. The Verdeons in Rancho Cucamonga still look good, though I have seen two that failed dimly, but the Navions that they use at their intersections though...

@BT25: To be fair, most LED street lights are serviceable to an extent. I've seen a few actually repaired though for the most part they're usually replaced completely as they fail.

Regarding Verdeons, I've seen the very same. PennDOT has been using Verdeons for a while now; there was a time when they used Autobahns, but that period was extremely short-lived due to the mass discoloration of their diodes. Now they're back.

Most Verdeon failures I've seen are 3+ year old installs. Usually 1 of 2 diodes turn orange, then die, but I've also seen completely oranged-out ones.
