convert a common home security light into a remote ballast grow light

Hey guys i found some info on my quest for more knowledge that seems useful for new growers and others as well looking for hps or Mh.



How do I convert a home security light into a remote ballast grow light?

Contributed by: Spliffco, Inc.

For some reason growlight manufacturers are completely ignoring the small, personal grower. A quick look around Overgrow and you can see some very respectable bud being grown under 150's, and even 70 watt HPS lights. But the smallest ready made remote ballast growlight you can buy is a 250 watter, and they usually cost well over $150 (US).

So, as usual in the medicinal herb growing world, you need to take matters into your own hands.

Here’s how to turn a 150 watt HPS security light available at most Home improvment stores, into a nice remote-ballast grow light.



Materials & Tools:

MATERIALS
Regent GT150H, (About $79)
Heavy Duty extension cord of suitable length
One heavy duty grounded electrical plug end (male)
Electrical box
Electrical box plate
Romex cable connectors (3)
Wire nuts
Bolts, nuts washers
Strip of metal to secure ballast
Project case from Radio Shack ($6.99) #270-253A

TOOLS
5/16 nut driver (for removing parts from the casing -- regular pliers will work)
Philips head screwdriver
Regular screwdriver
Hammer
Power drill and assorted bits
Metal file
Wire cutters
Utility knife or wire stripper
Diagonal Pliers
Pliers

Wiring Diagram
Be careful...



Remove guts

Remove the guts from the casing - bulb socket, ignitor, light sensor socket, ballast. The ballast was glued to the casing. I heated the casing for a couple of minutes on an oven burner (high), and when it was getting too hot to hold, I put it on the floor and wedged a hammer between the ballast and casing and popped it out gently.



REMOVE LIGHT SENSOR

These security lights are designed to automatically turn on when it gets dark, so there is a built in light sensor that needs to be removed.

Remove all wire nuts.

Disconnect the white wire that comes out of the sensor (currently connected to all 3 other white wires).

Disconnect the black wire that comes out of the sensor (currently connected to the black “power in” wire).

The red wire coming out of the sensor is currently connected to the black wire coming out of the ballast. Remove the red wire, and then connect the black wire coming out of the ballast to the black “power in” wire.

Reattach wire nuts (there were 5 originally, now you only need 4).

Refer to the wiring diagram!



WIRE THE SOCKET

The socket on this particular light had some metal wiring connectors that stuck up and made it impossible to attach to the electrical plate without some modification (sorry no photo). Just pull the black and white wires off of the connectors, and cut the connectors down flush with socket base with diagonal pliers. Now loosen the connectors (screws inside the socket), slip the wires under them and tighten them back down. Please use some plastic electrical tape on the end of the socket to prevent any chance of the metal from the connectors making contact with the electrical box cover plate.

Secure the cord in the electrical box with a romex cable connector and wire it to the socket: black to black, white to white, secure with wire nuts. Some electrical boxes have a green screw inside to fasten ground wires, use that if yours has one, otherwise fasten the green ground wire to the box using one of the cover plate screws when you tighten the cover plate.



WIRE THE REMOTE BALLAST

Hopefully you can see the wiring clearly in the photo, but if not, refer to the wiring diagram for details.

You’re going to have to cut some holes in the Radio Shack project box for the power cords and some bolts to hold the ballast, ignitor and ground wires down.

I used a short length of metal (plumbing department) to secure the ballast. The ignitor had a notch that made it easy to bolt down. The ground wires from both electrical cords are screwed to the base of the box.

Cut a short length off the socket (female) end of the extension cord and wire it appropriately (again - see diagram). Wire the remaining electrical cord, including the grounded male plug to the other end of the box.

Use a tie wrap to bundle up the wires in the box and try to keep them away from the ballast, which will heat up during use.



TEST IT!
If you've done everything right, it should light.



Now, build a reflector and you’ve got a nice little custom grow light.

Safety Warnings:
Always wire the male plug to the bulb socket and the female receptacle to the ballast to avoid possible electrocution! Always use an all metal project box which already has ventilation cooling slots, or if your project box has none, please cut adequate cooling slots, or drill several vent holes in the ballast enclosure (project box) to allow the heat to escape the box. Not adding the cooling slots or holes, could result in failure of the insulation and/or the transformer. Also, please be sure the enclosure is located in a well ventilated area to aid cooling.

Just Be CAREFUL and use CAUTION Or this could Happen

The painful truth :

This person lost the use of 3 fingers, which took over 7 months to heal.The thing that worries Overgrow / Growfaq is the fact that most people don't understand, or believe that most of the time this beast kill's and does so without warning.

Most Overgrow members wouldn't want to be put into an electric chair, but will climb into one willingly while wiring a room, opening a ballast, building their own ballasts or other devices, you name it.

Electricity can and will kill you if you don't respect it!

Make Sure you Use the correct Ballast For the Hps with only the right wattage bulb! These are not conversion Ballasts Repeat these are Not Conversion Ballasts do not use MH hallid Bulbs for hps security lights or an Hps Bulb For A MH Security Light hope this helps many of you all out

This is a very inefficient way to actually do this and is MORE expensive than getting a 400 W light kit with a reflector, reliable ballast and solid workmanship.

One example is this. http://www.htgsupply.com/viewproduct...roductID=47929
or look on e-bay.

Cool guide to making someting like this, but it still seems way too inefficient in costs and safety compared to just ordering one from somewhere reputible where you will get more wattage.

Thank you for making this post this is exactly what i have!!
Ive wired it up the first time, all i need to do is make sure everything is tight and secure inside a box and make a safe plug, easally achievable if you have a brain and know how to use your "drill and screwdriver" skills . Thanks

Depends on how you look at it because i can find these security lights for 10-20 Dollars i think this light someone got ripped of on cause there aint no way in hell id pay $80 for that id say it would cost $50-$60 total for all depending on where your buying
