Hi all,
I am new to this site and excited about it! I recently purchased three 26W Low Pressure Sodium Vapor Lamps. I'm a theater designer and am interested in using two of them in a show I have coming up in a few weeks. I am very new to the world of SOX lamps and am having trouble finding the correct Ballast for them. I was hoping to get an electronic ballast because they seem easier to find/cheaper and I don’t need an ignitor but am unsure which one to get. I know it needs to be at least 26Ws but can it be more than that? The system I’m running it on is 3 phase power, 120v, most bulbs we run on this system are 750w so I’m not really worried about getting power to it. Mostly just how to get it to actually work. I’m attaching a link to the bulbs below.

Also if someone knows what kind of base is required, It says it’s E26 but I’m not familiar with the bipin setup, do I need worry about the voltage since it is a different base then a typical E26?


Sorry for the long list of question
I appreciate any and all help!

Today I found two 36w tubes on the side of the road, and I decided that they will be my lab rats for homemade grooved tubes. I don't think it is possible to bend the tubes at an angle but I will try it soon.
(I will use my dead tubes fIrst then these working ones)

Too bad I don't live in the UK. I've been working for this dealership for 5 years with three 1,000 watt MH floodlights that I am trying hard to keep lit, sometimes out of my own pocket. In the process trying to prevent the GM from noticing any of those lights out and therefore telling the maintenance guy to replace them with LED.

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?
