One of the issues is also that those Caster lamps on eBay have undersized arc tubes so they will work better on the post-2000's generation of low-quality yard lights that underdrive lamps somewhat, but on an older, better quality fixture such as your Norelco, they will be overdriven and thus burn whiter than a vintage lamp would in the same fixture. You will also get drastically shorter life (in short - Caster lamps are poor quality). So, if you are planning to use the fixture more than just for display purposes and want a clear lamp, I'd absolutely recommend investing in a good quality, new old stock lamp. Or even a good quality used lamp i.e Philips, Westinghouse, Sylvania or EYE that was made at least a couple decades ago so take Maxim up on his offer!

Do you know what wattage of HPS the M250R2s are?

I love chocolate milk and whole milk. And hot chocolate as well.

I just confirmed that it is a IDOT controlled project.

Scored a very rare cold temp magnetic HPF Trigger Start ballasted F15T12 fixture on Ebay earlier this morning around 12am, I believe. Bought it immediately,
as soon as I saw it. It was the only one available though. The rest that I've found are LPF standard Rapid Start ballasted fixtures.
I'm waiting for it in the mail, but will post it in my gallery once I receive it.
I now own 7 cold temp HPF magnetic Trigger Start/Rapid Start ballasts.

@LightsoftheWest, I've had In-N-Out, back in 2014 when I was in Los Angeles California for a bit. Highly agree... In-N-Out was really good!
Very delicious burgers and fries there! Dave's Hot Chicken and that Mediterranean spot both sound good as well. I'm taking notes in case I ever
go to Phoenix, especially with the girlfriend, if I ever do find my girl. 

Not related to this thread, but what sort of LED fixture are you using as the replacement?

Here is a video about the history of National/Panasonic’s TV jingles in case you are interested.

National/Panasonic is a well known lighting manufacturer in Japan that also manufactures other appliances and electronics as well.

For those that don't know, that's a GE Americana AM8X.
