70w hps ??

[HOMEGROWN4DE]

So I just got given a 70w sodium bulb and was wondering if it's worth buying a ballast to use it, I am using a 250w cfl for flower at the mo but my blue cheese is nearly ready to flower and was wondering if there was any advantages to changing lights???? also does anyone know the lumen output of these bulbs???? any info would be great! thanks

I really don't think that you need a ballast with lower wattage HPS bulbs.

Doesn't it fit into a normal light socket?

yea it's a e27 srcew fitting but I tried that last time and it blew my house fuse! lol I just asumed it would need 1 after that?????

 

[Lil Czr]

That's odd, I guess that circuit was overloaded.

Try unplugging something and see what happens.

I just don't wanna blow the bulb up coz I don't reckon he'l give me another lol

Yes you do! the ignition system is totally different.

ALL mh/hps bulbs use a ballast, no exceptions.

any ideas how much this will set me bk? I'm in the uk so home depot isn't an option lol, the amount of ppl on here that say go to home depot is mad! it sounds like a one stop grow shop! lol

You are right, I was wrong.

oh and is it worth the effort gettin one??

so I went and bought a complete 70w hps light just as a little extra for my baby, do these lights actually make any differance???

I do know that an 250 hps is aprox 30000 initial lumes and 600 are aprox 90000 so my educated gues would be approx 8000 initial lumes. Of course it varies depending on the company that makes the bulb and the shroud you use.

The hps bulbs are unmatched for the flowering phase. Your compact floresents or metal halides I would only use for the veg phase.

amen.

you NEED HPS. not a question about whether it will help.

150watt HPS is ~16,000 lumens. That is, a GOOD bulb. Some random 70w HPS, i would say realistically is 7,000 lumens.

thats GOOD though, thats a ton of light, for just one plant, maybe 2 with the cfl's added.

Hello, i don't mean to hi-jack this thread but i think the question is relevent, I'm thinking about going out to buy a 70W HPS and i was curious if they fit into smaller grow box than their bigger versions... specifically, i hear people hanging 250/400W HPS bulbs at least 18 inches to 25inches away from their plants but would you be able to get the smaller 70W HPS bulb about a foot from your plants or will they receive burning from the lumens and/or the proximity of the lamp?

(p.s. i don't really know what lumen burn is but it seemed like a possibility with so many lumens coming out from a single position, so close)

i always wanted to side light with the 70 watts
