1 ballast 2 bulbs

[BarraCudaTM]

I'm thinking of using 1 single ballast to drive 2 MH bulbs

I know its possible with FL, just want to know whether MH is the same

high wattage ballast are cheaper than multiple low wattage ballast

what do you think?

Is it possible? There are no ballast that are of compatible wattage to drive 2 bulbs.

Maybe 400W to drive two 175W?

[BarraCudaTM]

since there are 1kw bulbs out there, there should be a matching ballast

[Tanzy]

Now I am confused. You want to use a 1000W ballast to power how many bulbs? Four 250W?

[BarraCudaTM]

errr .. just stating an example

[Tanzy]

Then I hope an electrical engineer chimes in on the feasibility of the project. The price of ballasts across the wattages don't vary a lot, neither do bulbs too.

if its possible ... then I can save $$ to buy 1 ballast instead of 2

i really dunno if that's possible to string a ballast for the lights ... ie 1000W ballast for 4 x 250W lights .... so you gonna string them in series or parallel ... if series .... if 1 gets blown ... the rest will not be able to work ... but in parallel , you will need 4 times the current for each light ... so it's quite tricky ... need some electrical guy to sought that out for you !! <_

May not be possible as MH bulbs have certain ballast designed to run them. Between a 1000 watt and 250 watt they will require a different striking voltage as well as current. 4 x 250 watt internal resistance is not the same as 1 1000 watt bulb. Either u burn the ballast, blow the igniter or bulb or do all at the same time or it won't even light up.
