ATBO killed 115s in my area along with GE ERL series when the ATBO series started failing 
I would go OVZ for ATBS

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

The first LED street light retrofit that I remember was one of these witch now I look back on it was probably cobbed. :a_sl:

1% of EOL to be non passive is normally treated as way too much for applications where this type of EOL may cause significant damage or harm.

But thereal key here is evaluating what is the hazard of violent EOL in your exact use case scenario. If you are lighting an interior which could be set easily on fire or when people would very likely be within the range the whole time the light is used, then it would be better to take it very seriously.
But when the only thing that gets reached by the hot shower is a pile of waste scrap with nothing flamable all around, you don't have to care that much.  The protection measures in open rated lamps are by far not that effective as a very low probability somone walking into an otherwise no risk area just when the lamp goes.

And there is another measure that is quite effective in how violent the explosion becomes: Not letting the lamp burn continuously for more than few days. The thing is, the arctube gets weaker gradually. But also the warmyp cycle exposes it to extra stress. So when the arctube state approaches the level where it becomes more likely to explode, it will do that most likely during the warmup (when the various thermal gradient stresses add up), when also the internal pressure is not that high yet, so the explosion energy is way lower than it would be if it exploded during steady run.
This recommendation was often added into the open rating condition wording, usually along the base up position.

That's interesting... does it not hurt to breathe in sandstorms? Seems like the people in each video are handling it better than I thought they would.

@wide-lite 1000, Smoked Gouda flavor... oh I'm definitely gonna do some shopping tomorrow before work then. Especially since they say
that the severe weather will be holding off until tomorrow night. If the Smoked Gouda Cheeze It's are up to date in terms of expiration,
I'll be snacking on those all night during each break at work tomorrow night. Same with the granola bars I'll be purchasing.
And yep, I'll work out and burn it off soon, but I generally don't work out if I've run out of protein shakes. (I recently ran out.)
Protein shakes are so expensive. I'll be purchasing the protein shake powder Monday morning after work though.
I still do have to cut back on my junk food intake... just drank a can of Sam's club cola.  :'-) So good, and really addicting. 8 out of 10
every single time. lol

The higher the wattage, the lower the fill operating pressure and temperature. Plus the ceramic technology becomes exponentially more difficult to produce when the sizes go up.
So it is mainly the lower power range, where the temperatures are the highest, what benefits the most and suffers from the manufacturing difficulties (so the cost becoming high) the least.
