Hello friends.

I have always been curious about this for years but never really tried to find an answer. Why do we have two different types of 150 watt HPS lamps? There are S55 and S56 lamps. One is 55 volt and one is 100 volt if I remember correctly.

I just always thought of 150 watt HPS being an oddball wattage because of this. I mean we don't have more than one type of any other wattage HPS do we?
