True,though i prefer these to the R3/A3 as they still somewhat resemble the original M-400.

I like the M-400R2 better myself, they seem more GE like than the newer M-400 models.

Yeah, I hold nothing against the current M-400/M-400A, but i do prefer the M-400R2/A2 over the M400/A

I'll try not to say anything

shame shame niall.

I know how you feel. Also, this may not be dead, it may just need a new lamp. But try telling that the modern lineman.

a Few Poles down from this one there was a 400 Watt MV GE M400R3 that was also out....it got replaced with a HPS M250R2 a while ago.

There's always a 50/50 chance it's either a defective lamp or the ballast probably may have went which is pretty common with these particular GE fixtures.

does this one have a GE logo on the door? And does it have a "GE signature" rims around the edges (its hard to see in the pic) but those designs can help see which generation this fixture is....if its a 1985 generation or a 1993 or so....They made 3 different generations (changing minor designs) The newest ones did not have either the GE signature rim or the GE logo on the door

now i didn't observe it that closely.

I like the M-400 r2, It was the first fixture type I ever had in my collection. It has a classic design and has a good lighting distribution, definitely better than the M-400 r3. The M-400 r3 FCO has that stupid line on the light distribution on the ground. M-400 r2 FCO has a pretty good and stable light distribution.

Yeah, i've noticed that same dark streak of light on M-400 FCOs too. I've never seen the M-400R2 in FCO.

I was actually told different from Silverliner14B about the GE distributions....he has all he fixtures in CA......

The line could be from the frame of the HPS lamp

could be,but isn't there also a Indention right under the lamp in the reflector?

True, that could be it. I don't see why the big three (GE, AEL, Cooper) have to "improve" their origional designs. They can add newer technoledgy without forming a new luminaire shell. What was wrong with the M-400R2/A2 and FCO companions?

He has a point ^

the M400R2 is sleek the M400R3 is boxy...now its an updated design but what true advantage does it have over the M400R2 aside from a powerdoor version?

the OV-15/OV-25's are still largely the same as the originals....as was the now Defunct OVL

The M-400A2 was the power door version of the M-400R2. They kept that bulky design so that the M-400A2 power/modules could be used on older M-400A lights. but yet the plugs on them were different so they're really not interchangeable without cutting off the plug so who knows lol. The M-400A2 FCO had a great distribution. The M-400R2 FCO i heard was sorta sucky...

Can they go long with a out lamp? would that hurt the ballast?

It depends. With CWA ballasts, a dead or missing lamp will hurt the ballast no matter what type of lamp it is (MV, HPS, MH, PSMH) but other types of ballasts won't get hurt from missing lamps. However, dead, cycling, or missing lamps will hurt the igniters in HPS and PSMH fixtures.

M400R2 FCO's have a better light distribution than Cooper OV-25 FCO's IMO.
