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)

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.

yeah id like to see the picture if thats ok?

Here's the pictures

looks pretty good. thanks

what kind of light was it when you bought it. like brand.

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
