Home Depot 50watt HPS

[greenerway]

Alright... I recently purchased a 50 watt High Pressure Sodium Light from Home Depot and the specs are:
50watts
530mA
120V
60Hz

I cant figure out how to get it running. I went to Radioshack and hooked it up to a normal extension cord and it didn't even flicker. I used an adapter that had 1000mA and with the same results. I'm not much of an electrician so I'm stumped and have googled a bunch of 'how to's and it's not working too well.
Any help would be appreciated. I've got 1 sprouted, 6 started today and 5 tomato plants on the way; so, I need to get this ball rolling.

Thanks

I assume it just plugs into the wall right? There may be something wrong with it. Plug it in and leave it on for a couple minutes and see if anything happens. It takes a minute or two for them to heat up. If that doesn't work, take it back and get another one. I don't know how many plants you plan to grow with a 50 watt hps system but it's not going to be much. I would say the 5 tomato plants will take up all your space if you plan to grow them under the hps. I would get a bigger one for what you have in mind. How big is your grow area? Keep us posted. Hope this helps. Take care and be safe.

I apologize, I was real vague. I am only starting the tomato seeds in the box and then moving them outside. I've got a bunch of CFL's in there and really only planning to grow 1-3 plants with that 50 watt. Its a micro-grow, like I said and a 100 watt would probably catch it on fire.
I just needed to know if the black(neg) and white(pos) wires would light up with the other half of an extension cord. I'll see what happens and let you know.

You have to tape the photo-eye with black electrical tape or something that won't let light into it. It will never turn on with any light on in the room.

Black is hot 120 volt, white is neutral 120 volt. Green is ground.
