400w hps w/ ballast...119$ new...(PICS)

in poland hps like that but homemade or parts for hps like this will cost something about 40-50$ i make my 150w hps for 25$ and i've got there 17,000 lumens i think that buying lamps like this is stupid because is very simple to do it yourself at home... peace and forgive me for my english language

few days ago i was wrote a worklog about hps building, i can translate it if anybody needs MH lamps, hmm, i never build this but i can find some info and write new worklog about. for this time i know only that some MH can be use with hps electrical configuration (ballast), but rest of MH lamps need different electrical conf

 

Ide really like to know how you made it. Since you might know more than me, whats a ballast? Is it necessary? Could you just replace the 150w bulb with a 400w and be set? I just yesterday start readin some info on indoor growin, sp pardon my noobness.

 

where did you get that set up for 150? i just payed 160 for a 150 watt hps and now i feel like an idiot lol

 

so:
HPS OSRAM nav-t super (son-t plus) 17,000 lumens NEW! is from allegro.pl (something like eBay), that was an auction and i won them and pay for bulb 5$ (bulb + transport)

ballast cost 15$ all, man from allegro sold me that for this small price

rest parts i bought in my town for 5$

heh, i think that's cheap xD

ok, i will write worklog about 400hps, please tell me what voltage u have got in your homes? in europe we've got 230V and u in america?

 

Most houses In US are 120v

 

Yes you got a very good deal on your 400 watt HPS. Yes you need a ballast to run the lights. If the ballast is rated at 250 watts you can NOT put a 400 watt light in there.

 

for 150watts hps bulb u must use 150watts ballast
for 250watts hps bulb u must use 250watts ballast
for 400watts hps bulb u must use 250watts ballast
etc

u can NOT connected 250watts bulb and 150wats bulb and use for them 400watts ballast

u can NOT connected 250watts ballast and 150watts ballast for 400watts hps bulb

 

"the ballast is refurbished, but it has a warranty" it has a warranty because ballast very rarely broken down, refurbished to...

 

i've got a problem:/ in us u've different ballast and i don't know to much about this... but i'll learn and learn

 

"cant i use 400w hps bulb with 400w ballast?" yes. and you can't use different ballast for this bulb, or can't use different bulb for this ballast.

 

I got my light from the same place, except I got the MH/HPS switchable. They are reliable and their prices are very compeititve. For those asking, the vendor's own website is htgsupply-dot-com. Sure it's cheaper to build your own, but like you I don't know nuthin' about wiring ballasts and would rather pay extra to get something pre-built and likewise would prefer brand new to refurbished.

This is their "econo" line, which works just fine. Only problem with their econo line, which I realized after I had bought mine, is that the cord from the lamp to the ballast is hard-wired at both ends. That means that if you want to put the ballast outside of the grow area you can't use a little hole for the cord because you can't unplug it, instead need a big hole to pass the ballast through.
