The old sodium vapor light on the corner of my barn finally quit working the other night. I bought a replacement at TSC. They didn't have any choices, just 1 lightweight aluminum one, that is a 65 watt outdoor florescent, supposed to be as bright as sodium vapor. I needed light, so I bought it...figured I can swap it out later, but need light now.
Let me tell you, it is brighter than the old one ever wanted to be! It is like doggoned daylight out there...for about 4 acres! And all for only 65 watts. I'm pretty sure the old sodium was rated at around 300 or so.
I don't buy much modern stuff, but this time, it is truly an improvement over the old and I am impressed.
