[giancarlolandrover]

HPS are goog but the life time the mercury lamp better!

[form109]

the way i see it each ending suffix is an slight change in design,and the general electric m-400's kept the same body shape right up until the m-400-r3/a3 came out.

How do you know the year of the fixture?

[tpirman1982]

They were first made around 1985-1986 until 1997

tpirman GE M400R2/A2s are now back said slaidblade.

[form109]

im Glad of that For Sure!!....i never Understood Why GE made Such a Drastic change...and decided to Base the M400R3/A3 off the AE 125.

HPS fixtures are more efficient but they require 2.2-4kV pulsed ignition current provided by the ballast, so they can be more dangerous.

to be honest i prefer mercury vapour lamps as they give off a soft glow but the HPS lanmps aren't that bad either

[tpirman1982]

Right, but Mercury Vapor lamps are the best, 'cause of their soft flourescent whitish tones.

I hate HPS Light, it's horrible,has a stupid yellow-orange colour, and very low CRI, Merkury Vapor bulbs, are much more better, that horrible HPS

[MrSpike13]

Mercury suck ass! Try Philips Cosmopolis

[Audi100C4Owner]

Shut up !

Mercury Vapor lamps are the best :)

[10x19AnninDefiance]

You suck ass!

[10x19AnninDefiance]

HPS Rocks!

[tpirman1982]

Yeah, me, too!

Brockton uses HPS lamps.

Holbrook, MA uses Mercury Vapor and it's the next town over from Brockton near Avon.

But Boston uses a lot of Mercury Vapor.
