Lustra inside

This is my Lustra LPS area light. I got it from my local veterinary clinic. It has been on their near by power pole as long as I can remember and it also has been out of service as long as I can remember too. I got permission from the clinic to take it down to have. So with help from my dad I got it down. Now the light is made by Lustra Lighting and is 35watt Low Pressure Sodium 120volt. This is my first LPS fixture and bulb. If you have any info on Lustra Lighting please tell my Thank You!
