I don't think those bulbs have a ballast in them. Read the box carefully. I believe they need to be installed in a fixture that has it's own ballast. In my experience, if it has a mogul base chances are good it is not a self-ballasted lamp.

FWIW, here is the ballast inside of a 105w CFL that I have (regular, not mogul socket). It's an identical bulb to the 105watter that ebay guy also sells (got mine from 1000bulbs though).



I experimented with various CFL's for a while. Eventually I decided they are fools gold for my circumstances. Sometimes I wish I could get my money back from the CFL's that I now have laying around.

Yup those need the fixture that has the ballast. I got 65w at lowes, after the cord $30 bulb included I will mount so it is fixed and horizontal with mylar on top of box. thinking of using for veg.

Fools gold is right though, in hind site, the hole using cfl's was a waste of money. I have 420 actual watts in flower box, and if it was full could use more. spent over $100 and could have a 400w hps for less. Switching soon just trying to figure how to cool the bulb for less than a cool tube and extra blower.

42 watters are fairly hot too. the built in ballast is probably hotter than the bulb. Pic of the 65 watt light.

Your 65w fixture has a 65w ballast. The socket size doesn't necessarily mean anything. You want a 100w ballast for a 100w bulb. They may light up being driven off a 65w ballast but who knows what intensity or spectrum of light you'd end up with.

$0.02

i looked at the ballast form mine and the 100w lights they where the same . i got mine out of 65w spot light. theirs also a 45? or 47w fluorex light but i think it has a smaller socket?? the one hundred watt bulbs said they where 1000w....and i have two of them :)

1000 watt equivalent light, 100 watts of power usage. a smaller ballast might light the bulb, but it will under-power it and not give you all the light it would normally give off. burning out the ballast is also another possibility.

get a 150 hps for 69.99 that will be better than a 1000 watt cfl

I've thought about getting a cheap hps like this just to get started, but the little lumens for the price, doesn't really seem worth it. how many plants do you think can be grown under a 150 hps? maybe 2 or 3?

yeah 3-4 but you will get far more buds than cfls. there is a guy who vegged and flowered 3 plants with a 150 hps and got close to 2 and half oz a plant.
