Meant to post about it yesterday but forgot... installed my final two Metal Halide wallpacks in my garage, making it eight wallpacks total.
Recorded video of them firing up yesterday as well but debating on uploading that video since the cords protruding everywhere near the garage
door opener makes it look a bit messy... still gotta tidy everything up.

Same. Mag reg ballasts fascinate me, but HX ballasts are the best for reliability.

It depends if the lamp is designed with vacuum vs gas (and then exactly which gas) filled outer.
With vacuum (lower power, ceramic,...), it quite makes sense to use there...

My name gets butchered all of the time and I live in the States!

It's pronounced 'Max-eem' whilst most people see the 'i' and immediately assume it pronounces as 'um', so in essence I am always called 'Max-um' instead of the "proper" way. I guess this is in part due to the natural spelling / pronunciation of Maxim in the Russian language being 'Максим', the second-to-last letter being an 'e'. Anyways....

After knowing that most high pressure sodium lamps have barium getters near the base of the lamp, I have noticed that some quartz metal halide lamps such as the GE/Tungsram Kolorarc and some Osram HQI-T lamps have them, but also some ceramic metal halide lamps such as some Philips MasterColor lamps and some Iwasaki Cera Arc lamps have barium getters.

Why were barium getters often added to certain quartz and ceramic metal halide lamps?

My favorite is HX for their reliability. No cap to fail.

Second would be mag reg. Love how beefy they are, and how they run lamps.

Personally, my favorite magnetic HID ballast topology is the HX autotransformer ballast because such ballasts allow for a very wide range of lamps to operate properly.

What magnetic HID ballast topology is everyone else’s favorites?

CWA, CWI, series choke, HX autotransformer, 2 lamp lead-lag, mag-reg, etc?

This morning, I went to a flea market, ate breakfast at Taco Bell, then went to Lowes and Goodwill and then the gym.

I got home, ate lunch and did a load of laundry. Then I started breaking down some boxes and throwing out some trash.

It was quite a busy day for me! Usually Sundays are my day of rest!!

It's weird because sometimes the flashing colors with my QMH lamps seem either pinkish orange or orange. The flashing in the ones at my gym class were orange all the time, and they would flash normally in twos or threes, before fully warming up.
The flashing with my 20w CMH are always pink, never orange... which makes me wonder about my CMH Philips lamp for my Wallpacks.
I've seen that lamp flash before warming up... but the flash from it was purple, and very slight. I have never seen that lamp do any orange flashing yet.

Went rock hounding...another hobby of mine...found 35 agates.
