Gross. How hot does it get after running for a while? Also, where did you get it from so that the fabrication date was January 2019?

Any machine is a smoke machine if you operate it wrong enough.

Probably pinched it right off the truck leaving the factory! Jk

At least it is warm white, it looks like it gives off a nice colour.

A 'green' cobra ... to go with the green walls

Colored Fluorescent's such as F40T12 Red or  Green or Blue are awesome...

It doesn’t get very hot... warm to the touch, I ordered it from the company through my local distributor using the same order code as my utility uses (so I have the exact model they are replacing the 201SAs with. The green walls weren’t my choice and yes, I did order 3000k Warm White. When the one outside my house hits the street, it looks just like a DLX MV is shining down on it.

How much did it cost, and how do you know what the utilities are using?

I find it strange that you guys talk about lanterns getting hot.... The two cobras I have don't get hot even after running for an entire night!

In fact the ballast itself doesn't even get more than Luke warm... The only thing that gets hot is the lamp, glass and reflector but that doesn't spread to the lantern body (Atleast for me)

Now my NEMA bucket and other lanterns get hot... But I have yet to see my cobras get remotely there..

I stopped one of the Ameren techs and got the order code off the box. It was $288.23 including tax and shipping.

HomeBrewLamos, what wattage are your cobras?

The 250w HPS M250R2 gets very hot unless it is in negative temps

In my area, the DOT/Utilities have adopted 3000K-3500K LED street lighting, after initially installing 5000K lights.

I actually quite like the warmer color.

However, the only issue I have with LED street lights, and it is slightly aggravating, I live in a hilly area with curvy roads meaning in my peripheral vision I can see these street lights and often I mistake them for a vehicle and need to do a slightly panicked double take because sometimes I think I am seeing a car....

When I was a kid, all car headlights were brown-white incans with mostly MV and some HPS street lighting, and California had lots of LPS. And as I got older the HPS took over. But nonetheless, there was way more color contrast between vehicle and utility light sources. So, whilst I like the LED street lights, they do spook me sometimes.

Nice! Long time no see, sir! RIDOT uses the LeoTeks here on the freeways. They used 133W to replace 250W HPS and 280W to replace 400W HPS. When they were in their early stages of the conversion they were using 145W for 250W HPS replacements. All are 4000K but are yellow-shifting, a very common issue with Leotek lights. The ones here installed in 2016 have shifted to almost a 3500K color in a matter of 2.5 years. Saddening. I personally like warmer tone LEDs anyway, but the CRI has gone down too.

@ Owen: Some ballasts run hotter than others. The Advance HX 100W MV 120V ballast in my Powerlite R37 (not original ballast) runs very hot. You can't touch the ballast after it's been running awhile. Fixture itself is warm, but not hot. Most of my 175W MV fixtures run fairly hot. Not absolutely scorching but you can't hold your hand on top of the light for more than 10 seconds or so. And you can smell burning paint/varnish (and plastic if a plastic refractor is used). Granted, the lights are supposed to be used outside. In the proper environment I don't think the fixture would run quite as hot. 250W HID in a small fixture runs scorching hot.

To resist is to piss in the wind, anyone who does will end up smelling.

I noticed that the GE Evolves that were installed around January of 2018 in my area have gone from a very nice, halogen-like color to a higher color temperature slightly. Kind of disappointed since I really liked how the color was very similar to halogen outdoor lights. I also noticed that some newer ones still have the "original" color. Also, I found out that GE has 2700k as an option on the Evolve. I'm kind of curious to know what that would look like.

They're shifting bluer? Very odd! Sounds like the phosphor is degrading. Never heard of that happening so quickly. Usually LEDs shift warmer (lower color temperature) over time because the diode wears out before the phosphor. With Leotek, their lights yellow-shift at a rapid rate because they are probably driving the LED chips to hard (or they are using an inadequate heat-sink). If the fixture has a 0-10V dimming ballast, dimming the fixture will prolong the life of the LEDs by making them run at reduced power.

Hi Mike, good to hear from you again. I was attracted to the 10 year warranty, so if it mucks up, I’ll just snag a replacement. The GCJ doesn’t really have a heat sink, but it never really gets hot. Just warm. The higher wattage fixtures probably need the heat sink. Mine is rated at 39.7 watts to replace a 100w HPS/175w MV.
