is it possible to use high preasure sodium lighting to maintain coral? i know this type of lighting works well for incouraging growth in plants.

I guess the question is why would you want to? You probably could use them, but their Kelvin value is really low, I'm guessing around 5000K. That's close to natural sunlight and you would probably get some good growth but your corals would look really ugly. I've used 6500K before and was amazed at the difference when I went to 10K.

Mount them in your backyard, shining on your salt water pond, for lighting at night.

Put them back on the plants. They encourage flowering. :skeezy:

Sodium bulbs are pretty energy efficient though. That's why you see them used a lot for street lighting. In addition, the yellow color doesn't attract bugs as much as white lights do.

BTW, if you are going to throw them away, they are a hazardous waste. They contain mercury. Take them to the city household hazardous waste site.
