Unbranded 400w Green MH Here's a 400w green MH lamp going by what the sleeve says, the lamp itself has no indications that's it's green though. The right pic shows it running on a 250w MH ballast in my R47 which is big enough for a 400w lamp if you move the socket all the way in. Keywords: Lamps

Unbranded 400w Green MH

Here's a 400w green MH lamp going by what the sleeve says, the lamp itself has no indications that's it's green though. The right pic shows it running on a 250w MH ballast in my R47 which is big enough for a 400w lamp if you move the socket all the way in.

Surprisingly this thing is pretty green, it's like how clear mercs show up on camera.
GEsoftwhite100watts   [Jan 15, 2013 at 03:11 PM]
Sounds interesting...but greener than a greened-out clear MV?
streetlight98   [Jan 15, 2013 at 07:36 PM]
Is it still as green is it was in this pic?
joe_347V   [Jan 16, 2013 at 02:14 PM]
It sorta looks like a lime green colour instead of the bluish green colour a clear merc has.
streetlight98   [Jan 16, 2013 at 08:56 PM]
Hmm that sounds like it's probably a green MH lamp then, though I've never seen colored MH lamps in person before. I thought the glass was simply colored... Neutral

they have a different fill gas in the arctube, same goes with different kelvins
streetlight98   [Jan 16, 2013 at 10:10 PM]
Hmm metal halide seems quite flexible in terms of light color. If only there was a way to make HPS a little whiter without hurting lamp life, light output, or price... I know GE made some sort of lamp like that but i heard they weren't cheap...
A_lights   [Jan 16, 2013 at 10:37 PM]
yeah i think the name is Phllips cosmopils in Europe at least from what ive read/seen on LG
joe_347V   [Jan 17, 2013 at 02:30 AM]
Yeah I think they also change the composition of the halides in the lamp too.

As for the white HPS lamps I think Eye also makes or used to make them. I heard they're pretty expensive though.
streetlight98   [Jan 17, 2013 at 02:45 AM]
even regular eye lamps are expensive, though they come up with some cool uncommon lamp styles.
GEsoftwhite100watts   [Jan 17, 2013 at 11:43 PM]
And still make good quality lamps, in BT shape to boot! Very Happy
streetlight98   [Jan 17, 2013 at 11:58 PM]
Yep. Eye makes the best quality lamps but with high quality comes a high price. Sylvania makes good quality lamps at a more economical price, though when it comes to LED and CMH i think Philips comes out on top. GE is decent quality too but you get as much for your money as you would withg Sylvania IMO. The only thing is that Sylvania Eco HPS lamps don't always work on Cooper fixtures becuase of the ignitor. That's what it says on the sleeve of my 400W Sylvania Eco HPS lamp. Neutral
GEsoftwhite100watts   [Jan 18, 2013 at 12:03 AM]
Hmm that's odd...
joe_347V   [Jan 18, 2013 at 03:46 AM]
I think Eye is also the only company that still makes 700w ANSI spec mercs. They also made a BT shaped 2000w merc too.

Anyway, I also have a 400w Sylvania Eco HPS but the box dosen't mention anything about Cooper fixtures. The box does say satisfaction guaranteed though. Laughing

ahh mine has a sleeve (it's a utility lamp not a retail lamp). I haven't gotten around to troubleshooting my 400W Westingohuse ballast and i jsut might not get to it at all...
joe_347V   [Jan 20, 2013 at 10:31 PM]
Ahh, I see most of my retail lamps were from the Lowe's clearance while my utility lamps were from Restore. As for your 400w HPS ballast, have you tried changing the cap. I think the cap might be causing the problems.
streetlight98   [Jan 20, 2013 at 11:08 PM]
I think it's the cap too but i haven't gotten around to getting another. Basically i just need to match the voltage and UF ratings on the existing cap?
joe_347V   [Jan 21, 2013 at 02:49 AM]
Hmm, you have to match the uF (or combine to match) but voltage can be the same or higher than the old cap.
streetlight98   [Jan 21, 2013 at 02:25 PM]
Ahh okay thanks. Smile Is that all that needs to be matched? I'll have to get the ratings.
joe_347V   [Jan 22, 2013 at 05:16 AM]
Yeah that's all you need to match. If you can get the ratings here I can see if I can find a eBay link or a 1000bulbs link. Razz
