hi, i have a metal halide fixture, but i want sodium light, it is a 400 watt halide fixture, i also have some 100 watt sodium fixtures, i want a 400 watt sodium, is there any way i can do this with what i have, or buy a small part to make the halide ballast a sodium?
i need help please
i need help please
If you're using this for DIY projection, you don't want to use sodium. It's too yellow, doesn't have spectrum in the right places.
If you're not using this for DIY projection, this isn't really the place to ask. But, no. You can't directly replace a halide light with a sodium one, except in special cases where the bulb is specifically designed as a conversion. And usually it's a conversion halide bulb that runs on a sodium ballast.

the ballast should say wether it will take both on mine it say's MH/HPS which obviously means it will take either i actually bought it as a HPS set up and popped a MH bulb in but as already said HPS will not be suitable for projection
DONT TRY AND PUT IT IN THE HALIDE BALAST.....you can get a conversion bulb.....but as far as using a sodium in a halide balast.....dont....the gas is dangerous.....be cool...
The conversion bulbs are all over ebay for $30 buy-it-now if you really want to go this route. The actual color is more reds and yellows, but looking at it you see more of the yellow.
Yellow light is the most efficient as far as moving without losing brightness and may even work GREAT in our projectors. I understand people probably think the picture will be too bright or washed out, but why not try it? Does our MV/MH look too blue, seeing it's mostly blue light they create? NOPE. How many of you have actually tried it before knocking it? You COULD buy a filter to filter out the yellows if they were a problem, this seems feasable.

SMC,
You are new and seem very excited about diy projectors. Your thoughts are great but try doing a search on some of these things. Many topics are well researched already.
Sodium for example See attached:
The LCD filters blue, green, red. Every other wavelength is absorbed hence the need for powerful lights.
You are recommending a primarily yellow light so almost all the energy will be wasted. Some people go big wattage because of poor choice of lamp.
Surprisingly the most popular lamp by ushio has poor red output. Im not sure how people fix this - maybe pump up the red in the OSD - but it maybe why they go 400w and many want more.
If you want to try this sodium lamp let us know how your experiment goes.
Cheers.

The point I was trying to get across is for people to be unique and try things that only a few others have. I never recommended using one, just tried to explain how yellow light works and how it may seem beneficial. The good thing about HID is the assortment of bulbs, they DO make HPS lights that are more full-spectrum, as they do with MH as well. If I get a HPS it is going on my plants, I already have a 400 MH setup.
Thanks for the reply!
