Looks like it was originally a M-400 based version .

 The worst I've bought was a Feit RGB bulb . IT SUCKS !!!!  It has NO memory circuit in it so you have to set the color/Light pattern everytime you turn it on using a tiny button on the side of the neck . Accidentally dropping this P.O.S. was the best thing that ever happened to it !!

I have just decided that MARSHMELLOWS!!! are my new favourite food

Hello everyone,

As the end of fluorescent lighting approaches, we’ve started to see many fluorescent tubes—such as special-size models, very cheap no-name halophosphate types, and Panasonic branded ones like the FHF32—marked with long alphanumeric manufacturing codes like the one shown in the image.

The only common factor seems to be that they are made in China.

Does anyone know which manufacturer actually produces these?

I bought two 4-packs of GE Reveal HD 2850K 5W and one 4-pack of the 8W to relamp the hallway lights.  ALL of them had failed after 8 months, and some started failing after only 2 months. None of the fixtures are enclosed or recessed either, so there's no excuse for this.
I will never buy GE bulbs again.  In fact I will never buy any premium price LED bulbs again, I just buy the cheapest bulbs I can find.  I am not wasting money on that again. Absolutely enfuriating.

About that 589nm line seen in some lamp spectrums. 589nm of course screams Sodium!!! loudly ) So it is easy to understand we can see a marker of ever-present sodium impurity, with it's very intense resonant radiation, likely from oxide coating, as the lamps discussed here are mostly NOS.

I was looking at the old AEL website on the Wayback Machine, and found the 110 series in the 'Security Lights' section, and was wondering if anyone knows if they were used by any utilities, or towns etc..., they have a European look to them, perhaps rebaged?

They do have a Spanish or Italian look to them I would say…

High of 85 (with 5% humidity) here today.
A coldfront is on the way for tonight which will drop temps back into the 60's tomorrow.

Yeah, private property would probably be the last hope, but that said, it seems like it was made to have better optics than a NEMA, but cheaper than a Cobra. Probably good for rural roadway lighting.

I've never seen one, but finding one would probably be futile since there are probably none left anymore.
