Last night it was a 250w Merc. Today its a 400w HPS
This GE M400 FCO 400w HPS replaced an old ITT/T&B fixture that had a browned-out lens and dim merc in it. Turns out that despite the yellow 400 sticker, it's actually a merc!
My electrical company continued to replace mercs until 2nd quarter of 2008....the last mercs to be was the GE M-400A3 with sag lens (and you could see the coated lamps) and the GE M-250R2s with sag lens and the AE 115 with a sag lens also!
Actually jace we used M400R3's for the 400w mercs! Which was really dumb as the capacitors are horrible so instead of changing a door to upgrade we have to change the whole fixture.
The caps in the R3's are a different brand! I'll have to look to remember the brand but their not GE! Yes they are bad, if we get 3-5 yrs out of them were lucky! The R2's hold up pretty well!
