I have come across a bunch of metal halide
 

They are 400 watt how do I know if they're able to use for tanks ...

If they are good for tanks I'll want to sell them for 25 bucks if anyone is interested

Metal Halide what? Blubs? Ballasts? complete fixtures?
What bulbs? what ballasts? what voltage?

should be good. it's comes down to the bulb in it for spectrum. However 400 watts is a LOT of light. only people with deep tanks would be able to use them without frying most of their inhabitants.

Take a look on the bulb themselves and see if there's a temp rating on them. Eg. 10,000 K, 15,000K 20,000K

Oh ya hahaha I guess I didn't put that in thier just bulbs and they are venture and standard and sylvania

Can't seem to find a temperature for the bulbs but I'll have a better look when I'm not working

dual ended? mogal?

Mogal

New in box?

Not new but I don't believe they have ever been used...I didnt see a spectrum value but I didnt fully look at them yet we got busy and I forgot to bring them home at the end of the day. I'll be able to have a better look at them tommarow

Also I am not really fussy about price I have no use for them so I figure why not help others out a cheep cost.

So I have in packaging

3 - metal arc sylvania m59 400w 36000 lumens(not sure if this is what is needed) not ever fired yet as far as I've been told

And

4- standard m155 400w 4000k that look like they have be fired but do not look burnt out

I can't imagine anyone wanting to use those on a tank. In a workshop or warehouse yes but they would look horrible on an aquarium.

Looks like the bulbs are meant for something else than fish tanks. Maybe store or warehouse usage. 4000k is yellow

Looks like we had the same thought the same minute

Ya they are for street lights I dont use mh so I didn't know what to look for was Gunna toss them so I figured I see

You come to Edmonton very often? No useful for fish tanks, but good for parking lot lighting at my parents office building.

Metal Arc too, don't see those often anymore.

No never go to Edmonton lol sorry but I can still grab them is u want me to hold them pm me if u do we can work out a deal for them all if ud like
