What does that mean where it says it still has some daytime left?

[SpiritsoftheWolf]

@logster1203, ummm it means you can see the whole fixture before it gotten dark -_-

Just to put it out there that's an HPS or High Pressure Sodium lamp.

Mercury vapor lamps put out a bluish light.

[SpiritsoftheWolf]

@syphilistic, that is a mercury vapor lamp, not a High Pressure Sodium, if you still think it's HPS, then answer this, why does it comes on green after ignition, then turns pure white after full brightness, does a HPS comes on green after ignition?

[SilverlinerOV50]

A MV lamp will turn pink when warming up, please tell me what colour the light is from it when fully warmed up.

[SpiritsoftheWolf]

it turns on pink and greenish color after ignition then pure white at full bright

@syphilistic Digital Cameras tend to Incorrectly Render Mercury Vapor Lamps in color...often they will show up as Yellowish or Excessively Green.

Are you sure that's a mercury? Looks like a sodium. Anyway, yup, pretty annoying ballast buzz.

@goorance it's a Lamp...does what any other lamp does...Produce light.

[glasstronic]

I'd shoot it out. problem solved.

[logster1203]

@SpiritsoftheWolf Sometimes a HPS starts out green/white after ignition, then turns to its Amber Color. Mercury Vapors start out green after ignition then go to their bluish/white color.

[logster1203]

@syphilistic If its orange, it could still be a Mercury Vapor. Most mercury vapor lamps are bluish white, some of the new mercury vapor bulbs are different colors, so it can still be a Mercury Vapor.

[goorance]

Can anyone explane me what this "Mercury-vapor lamp" do?

[form109]

@67tr876 it's not the Lamp....Digital Camera's tend to incorrectly render the color of Mercury Vapor Lamps,while white or blue green to our eyes the camera will render it as excessively green or yellow.

[67tr876]

@form109 Well i could be wrong but its just i have not seen a MV lamp with that color. It should be white or a blue green. But not look like HPS.

[form109]

@67tr876 how did you come to the conclusion that this is not MV?
