low pressure bulbs?

I think i have a low pressure bulb can anyone tell me how to tell ?

not sure i understand... you think you have a HPS bulb with not enough pressure?

or you think you have a legit low pressure sodium?

where did you get it?

It won't work.

i think i have a low pressure bulb instead of a high pressure bulb it works it's orange i was curious to know about the odd like baseball shape of it. i got it from a buddy of mine 2 years ago i need to change i know....

scratching head

I'm not sure how to tell. Does it look similar to one of these?

I would look for a model number on the bulb and then search for the number on google.
