you want me to do the maths? ok
the cfls are
4x27watts=108watts
4x1750lumens=7000lumens
the hps is
1x70watts=70watts
1x6300lumens=6300lumens
the hps is much more cheaper to run with just a slight lowering of lumens. i see what you mean |

Yup. I was gonna go CFL for the new veg room, but am going with my old HPS 70W. Might add in a couple CFLs On the edges. Though heat can be a reason to go CFL
(I've also noticed the CFLs don't last nearly their rated lifetime)
I ran a test on the 70W'er yesterday, it pulls 83-84 watts and 1.62amps.
(I also wish people would stop talking watts and talk lumens and color. Watts is fine for the HPS/MH since thats the bench mark. Watts is Ac consumption, well power dissipation. I'm running a light, I wanna know the light output) Quote:

i have a question, instead of taking the whole thing appart and potentially ruining it, could i just take off the light cover and just put duct tape or something over the sensor so its always dark which means the light is always on. I probally could wire it but i dont wanna risk messing it up. |

The idea of making it remote ballast is that the ballast produces a lot of heat, move that heat away from the plants and you can move your light closer giving you better yields.
I modified one I have just a few days ago, I'll post pictures if you want. I have one without a light sensor, it's just a ballast, reflector and bulb in a box. All I had to do was open the box, cut the wire to the lamp socket and connect a longer wire. Plugged it in, works great. |

NCI, they're the kind sold at home improvement stores as hps flood lights, this one doesn't have a light sensor so there's less work modifying it. |

ha entropic., thats exactly what i did, i have a 70w security light and i just took extension cords and spliced them in between the socket and ballast to "extend" the length of the socket,, works great
