can you run a 200 watt bulb in a 400 watt lilight fixture.

I don't think so, the 200w bulb may not run at the same voltage as the 400w does. Some bulb companies make the lower wattage bulbs run as lower voltage and not the same 277v the 400w run at.
See if you can fine a fact sheet on the bulb and check the voltage. I know you can run a 400w in a 1000w ballast just fine.

NOOOO

no on that, no on the 400 into a 1kw ballast... NOOO non matching bulb/ballasts!

the bulb / ballast wattage MUST match... sure, the light may WORK in a different ballast, but over an extended period of time that growing requires, there is a good chance that, at the least, the bulb will crack or explode, and at the worst, will cause a fire... if you have made it through a whole grow with mismatched bulb/ballast wattages, then you were very lucky IMO

spend the extra few bones to get the proper bulb, and sleep better at night :twocents:

Opps guess the last 5 years of using a 400w MH in an extra 1000w transformer is bad then!!!! O-My-God!!!!

Bull Shit!!!

It's only going to draw as much amps as it takes to light the bulb. Instead of having 20% amperage in reserve (as caculated by the engineer) you have more like 40% so the transformer producess less heat and still put's out the amps.

Have I nice Day!

so are you saying i could use a 200 watt bulb in a 400 watt system, i have a 400 watt sunmaster hps bulb budding my plants and i think its the wrong spectrum to bud with and i want to get a 200 watt bulb so it will be cheaper on hydro

[Trichome Creator]

Depends on what the ballast is rated for. Point blank.

[mightymarijuanabuds]

thats nice and all.. but they are not made to be mismatched like that.

call me paranoid, but i'll stick with matching wattages on my gear

[SOB]

wouldn't the ballast be the same wattage as the light fixture, because the light fixture has 2 stickers on it, 1 sticker has the brand name and wattage which says 1500 watts then theres another sticker on the other side of the fixture that has alot of fine print and 2 blank lines, and on the one line it has the date the light was bought and the other line says 400 watts, i guess i might just get another 400w bulb for budding since i know for sure it will work in this fixture.

No not really, if you can depends on the voltage the bulb requires to ignight. Some don't use the same voltage as others so check the speck sheet so you know before you try. If the voltage is wrong then the bulb may light but it will burn up in about 5 min if you are not careful.

A 200w light bulb? This is just a guess but I say the voltage is not correct. 400w, 600w & 1000w are the same but not a 200w. I'm just guessing here but I bet the 200w is different.

so would i have to match the voltage for the bulb with the voltage of the fixture or the voltage of the ballast because i know the fixture is 600 v but not to sure what the ballast is. and if the ballast is 400 watts then shouldn't it make less noise then 1000 watt ballast would when turned on, im just woundering about the noise thing because i had a 1000 watt light last year and grew with that and it made less noise then the 400 watt light i have now does
