High Pressure Sodium, Metal Halide and Mercury Vapor.

Here we have the 3 kinds of High Intensity Discharge bulbs firing up at once. As you can see, the dimmest one is the mercury vapor when every bulb has reach full brightness, and that's because the HPS beat up the Mercury Vapor bulb in the market like a year and a half ago, but that doesn't means that MV is a bad and inefficient light bulb. Actually, Mercury Vapor is more efficient than incandescent and maybe even halogen.

Thank you for having all three to give comparison 🤘🤠🤙

I’m new here, but I wanted the comparison, cause in my street there’s the dim bluish almost green which I was sure are mercury vapour, and at the intersections there are the orange yellow ones and now I know they are high pressure sodium, and at the soccer field right near my house there are bright almost white lights that take ages to warm up and now I know they’re metal halide. And a few of the broken ones have been replaced with led 🤢

Where I live they still have some High pressure sodium. And the rest is L.E.D except the Home depot and McDonald's has the metal halied. I lived in Sandpoint since 2014 and the whole city used to have the HPS but got replaced in 2016. I go to some camp in November. And I see the Metal halied, hps and mercury vapor street lights

Metal halide seems brighter to me than HPS at the same wattage. The 70w MH was brighter than the 70w HPS. To you, which light seems brighter?

Huh? What? Can't hear you over the tornado

WHAT ARE YOU SAYING??? What is the noise in the background??? Your voice is so weak!
