Starting the grow again, need some advice

[Deadly Fear]

The one I was thinking about says 430, am I alright putting it in my 400?

while *some* 430W bulbs (are designed) and will work on 400W ballasts, not *all* are.

i would highly recommend purchasing one that clearly states it will work on 400W ballasts, like the one I linked in the previous post.
thats not a bad investment, $80usd...
again...strictly my opinion, and, im certain there are people out there that might be able to recommend a better and/or cheaper 430W optie.
but the one I linked you to isnt a bad choice at all.

keep em comin, if ya got em.

***edit***
the one you linked me to, doesnt state that it will work in a 400W ballast. only says it fires on 430W ballasts, so id steer clear of that one....

wasnt refering to conversion or the specialty rated 430's but i sure the heck wouldent recommend 600 with 1000's or a 250 in a 600. you get my drift, lol.

Yeah, see what you were saying there hubcap. Here's the 400w version which should work (and is cheaper ).

plantlighting is the best website. I use it for everything except liquids and soils in which case the shipping makes it the same price as my store around here.

im sorry, i dont agree with these statements at all. the, or any, 430 watt bulb IS made for 400 watt ballasts. the only difference between a 400 watt bulb and a 430 watt bulb are differing impedances. a lower impedance(resistance to energy) will allow more watts to flow through. therefore the 430 watt bulb has a lower impedance than the 400 watt. this can, and does, put extra stress on your ballast, requiring it to work harder. therefore, its not the bulb that you need to check for specificity!, its more so the ballast! some cant take the overdrive watts being created and would justifibly so, crap out.

the perfect analogy to this is, car audio. when your powering subwoofers in a car trunk, an amplifier acts as the powerhouse. same predictament with a lamp and its powerhouse ballast. in car audio, the impedance of subwoofers vary amoung models. this is to allow different wattages to flow through with differing combonations of subs! the subs could care less about their specific impedance at any given time, however the amp, has a greater to potential to die as its run at lower impedances.

does this make since to anyone? any physics people?

in an nutshell youre correct, buddin.
im not even going to go into the difference between impedance and resistances. there IS a difference, but, it really doesnt matter when talking these numbers.

look buddin...

most people look into the 430s because they want the added blue spectrum benefits and dont worry about a lil added current. (which is minimal if you crunch the numbers using the specific 400w ballast's 'schematics' and a 120v 60Hz 3 phase power source, ......commonly known as hosehold power in the US....id be surprised if one would be using anywhere close to an added amp of juice from 30w of bulb............so energy draw differences would be minimal......again.....this is ALL ballast related, like we agree on)

I simply recommend people use bulbs that "state" they are for use in a 400 ballast, because, it removes any doubt (all will 'work' not all will work 'good'...like stated....ballast dependant.....digis will prolly adjust better and more efficent, id assume.), and, also, expedites a FREE replacement much faster than "why did you use this bulb in a 400w ballast? its a 430?"
(when you and I both know the difference is minimal)

get my drift? im trying to offer this guy the most understandable and EASY/cheap approach to the grow. IF something should happen to "any ol 430 bulb" in his 400.....it'd be MUCH easier to get a FREE replacement if something went wrong with it. ...........As opposed to asking for a new one when it "doesnt state the product is used for it." (which is the exact answer youll get when returning it.)

there ARE reasons why manufacturers state whether to use their bulbs on a 400 ballast or not.............
and im certain its not ALL gimmickry.

make things simple....(and safe) buy using recommended products.

that was my advice.

"while *some* 430W bulbs (are designed) and will work on 400W ballasts, not *all* are."
is what i said.

maybe i needed to expand a lil bit......
its best to go with a bulb that states its recommened for use in a 400 ballast, so, if it DOES break, or something DOES go wrong with it, it will be free, and easier to replace than one that doesnt clearly state this info.
(just think of the customer service call.... "why did you use the 430 bulb in the 400 ballast? get my drift?)
Keeping in mind not all ballasts are the same.

that work fer ya?
