I think I may have lucked into a top notch grow light. Installed in the house we bought is a grow light. Th eprevious owner was an orchid growing MD. Here's the info on the light:

P.L. Light Systems of Canada.

Some numbers: LR48877
June 1993 (date of manufacture?)
PL90N (Model #?)
400 Watt High Pressure Sodium

The bulb is a Son Agro 430 Watt.

I looked online for other PL brand lights, and they all seemed to have the ballast as a separate module from the light bulb holder and reflector. My setup has the ballast and the light bulb socket as one unit, made from aluminum.

I tried the light, it works! It lights up when I plug it in, but after 2 or 3 minutes, it gets REALLY bright, kind of a warm orange or yellow color light. The reflector slides onto a rail that the light hangs from.

Is this perhaps an industrial light, or just an older hobby light? What's it worth?

Lastly, if I plan to grow stuff with this, should I buy a backup bulb in case this one burns out?

Thanks for helping a neophyte!

p.s. I can include a photo if it would help anyone ID this light!
